PSORIASIS

  • Coal Tar can be maintained as a safe treatment in dermatological practice.
  • Two double-blind, randomized, clinical evaluations were conducted to investigate the anecdotal belief that tachyphylaxis occurs in long-term treatment of scalp seborrheic dermatits and dandruff when using a single pyrithione zinc-based product. Evaluation of data showed a consistent benefit for all products at all time points; therefore, no evidence of decreased benefit over time was found within 48 weeks of treatment.
  • Traditionally used in an ointment vehicle for psoriasis, clobetasol propionate 0.05% is also available in spray, foam, lotion, and shampoo formulations, which may provide for improved convenience and acceptance with similar efficacy, safety, and tolerability as the traditional ointment and cream formulations. For patients who prefer a less messy vehicle, adherence and outcomes are likely to be better with the formulations other than the traditionally recommended ointment.
  • Topical vitamin B12 offers a new therapeutic approach for eczema (atopic dermatitis) and psoriasis, and may be suitable for long-term therapy as no long term adverse effects have been reported.
  • Salicylic acid has been used alone as a treatment for psoriasis, but is most commonly used to increase the penetration of other topical preparations, primarily corticosteroids. In this small study, the use of 6% salicylic acid gel in conjunction with tacrolimus ointment showed statistically significant improvement for the treatment of plaque psoriasis compared with the use of salicylic acid alone.

"For patients with localized psoriasis, and for many of those with moderate psoriasis as well, the mainstay of treatment is still topical therapy. The quality of life is greatly affected in such patients, and they often express high levels of dissatisfaction with current treatment options. Safe, convenient, and effective topical regimens, such as combination therapy with topical tacrolimus and salicylic acid, can be of great benefit in this large population."

  • "Methotrexate has been used as an effective systemic chemotherapeutic drug for psoriasis by dermatologists for over 30 years. Nevertheless, pharmacokinetic data indicate that oral methotrexate can cause a decrease in red and white blood cell and platelet counts and can also cause severe liver damage, diarrhea, and stomach irritation, as dose-related drug-induced side effects. Such indications have limited its prescription by physicians. However, [Syed and Nordstrom of the Department of Dermatology, University of California-San Francisco, and researchers from three other locations note that] if its incorporation in a gel as a topical agent, in a proper dosage. imparts better results without the cited side effects, then such a formulation appears to justify a clinical evaluation. Furthermore, published data have indicated that 70% of patients prefer topical therapy for treating psoriasis."

"Methotrexate 0.25% in a hydrophilic gel is well tolerated and significantly more effective than placebo as a patient-applied topical medication to treat psoriasis vulgaris."

  • "Methotrexate 0.25% in a hydrophilic gel is well tolerated but is not very effective in controlling the lesions of psoriasis on the palms and soles; however, a higher concentration in a different base with better penetration could possibly provide better results."
  • Tiwari, Kumar, et al. published a case report of topical methotrexate delivered by iontophoresis for the treatment of recalcitrant palmoplantar psoriasis. In a 46 y.o. male with well-defined bilateral palmar plaques of 6 years duration which were resistant to several therapies, the right palm was treated, as it had more severe lesions. Iontophoresis was performed using cotton gauze soaked in 4 to 6 ml of methotrexate disodium solution 10 mg/ml, once a week for four weeks. The researchers reported 75% improvement after four weeks of therapy. Iontophoresis allows high concentrations of drug to be delivered to a limited area, and may offer a method of reducing total drug accumulation and reduced side effects.

PRURITUS

  • Pramoxine Reduces Uremic Pruritus

    Wake Forest University School of Medicine conducted a randomized, double-blind, controlled comparative trial in a community hemodialysis center to evaluate the efficacy of 1% pramoxine hydrochloride lotion versus control lotion in the treatment of uremic pruritus in adult hemodialysis patients. Pramoxine 1% lotion was applied twice daily to all affected areas of pruritus for 4 weeks, resulting in a 61% decrease in itch intensity. “This safe, convenient and effective topical lotion may potentially benefit the large number of patients affected by pruritus associated with end-stage renal disease.”

  • Hydroxyethyl Starch-Induced Pruritus Relieved by Menthol/Camphor Lotion

    Hydroxyethyl starch (HES) is a key component of many colloid volume expanders used in hypovolemic shock and otologic disease. Pruritus is a common side effect. Although classically refractory to treatment with corticosteroids and antihistamines, some benefit has been achieved with topical capsaicin, ultraviolet light therapy, and oral naltrexone.

    A man with severe symptoms and refractory course was treated with a topical lotion containing 0.5% camphor and 0.5% menthol, which was dramatically successful.

    A randomized, double-blind, placebo-controlled trial showed a combination of menthol and phenol to be beneficial in mustard-gas induced pruritis.

  • Naltrexone for Post-Burn Pruritus and Severe Generalized Pruritus in Biliary Atresia

    “Severe pruritus is one of the many complications that burn survivors endure as a consequence of healing or healed burn or donor site wounds, [and] continues to be a clinical challenge that is inadequately addressed by traditional therapies. The success of naltrexone, an opioid antagonist, in treating pruritus in other patient populations, supported the concept that it may also be effective in burn survivors.” Opioid antagonists have been shown to suppress pruritus in patients with chronic cholestasis, uremia, atopic dermatitis, and chloroquine-induced itching.

    “Naltrexone is a well-tolerated medication with little adverse effects [and] may be an effective adjuvant treatment in the management of cholestatic pruritus in the pediatric population.”

Two studies used a topical formulation of 1% naltrexone (or placebo) for 2 weeks to treat patients with localized and generalized atopic dermatitis with severe itching. More than 70% of the patients using the 1% naltrexone cream experienced a significant reduction of pruritus. The cream containing naltrexone had an overall 29.4% better effect than placebo.

  • The following studies evaluated a topical formulation of 1% naltrexone to treat patients with localized and generalized atopic dermatitis with severe itching, and more than 70% of patients using the 1% naltrexone cream experienced a significant reduction of pruritus.
  • Itching Relieved with Topical Naltrexone

Pruritus is a very common and distressing skin problem. More than 70% of patients with localized and generalized atopic dermatitis with severe itching who used topical naltrexone 1% cream experienced a significant reduction of pruritus.

  • Aquagenic pruritus is an intense prickling sensation that develops in affected individuals immediately after contact with water at any temperature. Endogenous opiates, like naltrexone, can modify pruritus by influencing the peripheral and central sensation of itch, and have been found to be successful in suppressing the perception of pruritus from many diverse origins including aquagenic pruritus.

SUN PROTECTION/PHOTOAGED SKIN/WRINKLES

Topically applied antioxidants exert their benefits by offering protection from damaging free radicals produced when skin is exposed to ultraviolet light or allowed to age naturally. Appropriate formulation and use which is supervised by a knowledgeable healthcare professional will maximize the benefits while minimizing any potential side effects of these therapies.

Coenzyme Q10 (ubiquinone, CoQ10) is an important antioxidant that is taken to strengthen immune and cardiac function. The processes of aging and photoaging of the skin (due to sunlight) are associated with an increase in cellular oxidation, which may occur as the body’s own levels of CoQ10 decline. A reduction in wrinkle depth was shown following topical application of CoQ10 0.3%, and results indicated that CoQ10 has the efficacy to prevent many of the detrimental effects of photoaging. Wrinkles around the region of the eyes (“crow’s feet”) may be reduced by long-term application of CoQ10.

Vitamin C has been incorporated into a variety of cosmeceuticals designed to protect and rejuvenate photoaged skin. Ascorbyl Palmitate (Vitamin C Ester) is a lipid soluble, neutral pH, non-acidic (thus, non-irritating and non-stinging) form of Vitamin C which can reach cells within the skin rapidly in amounts greater than can be achieved by water soluble Vitamin C (L-Ascorbic Acid).

Alpha Lipoic Acid (ALA) is a powerful antioxidant and scavenger with anti-inflammatory properties that promotes optimum efficiency for production of energy and removal of intracellular waste products, essential for cellular healing and elimination of wrinkles and facial scars. Twelve weeks of treatment with a cream containing 5% ALA improves clinical characteristics related to photoaging of facial skin.

Topical niacinamide 5% (vitamin B3) reduces yellowing, wrinkling, red blotchiness, and hyperpigmented spots in aging facial skin.

Topical application of 0.01% estradiol and 0.3% estriol markedly improved elasticity and firmness of the skin, substantially decreased pore sizes, increased skin moisture, and decreased wrinkle depth.

Topical 2% progesterone increases elasticity and firmness in the skin of peri- and postmenopausal women.

DMAE (2-dimethylaminoethanol, deanol), when applied topically to the skin, may improve the appearance of sagging skin, boost the effects of other antioxidants, increase smoothness, reduce fine lines and give facial muscles a leaner look. In a randomized clinical study, 3% DMAE facial gel applied daily for 16 weeks has been shown to be safe and efficacious in the mitigation of forehead lines and periorbital fine wrinkles, and in improving lip shape and fullness and the overall appearance of aging skin.

Antioxidants such as vitamins E and C, coenzyme Q10, alpha-lipoic acid, glutathione, and others can reduce signs of aging.

Alpha-lipoic acid (ALA) 0.5% and proanthocyanidin (PA) 0.3% administered transdermally in a cosmetic formulation supplemented with 2% benzyl alcohol as a penetration enhancer, significantly enhanced collagen synthesis and deposition.

Topical Application of Phytonadione, Retinol and Vitamins C and E to Reduce Infraorbital Dark Circles and Wrinkles of the Lower Eyelids

Infraorbital dark circles and wrinkles of the lower eyelids are cosmetic problems that worsen with age. Fifty-seven healthy adult volunteers with dark under-eye circles and wrinkles were enrolled in an open label study to determine whether a gel containing 2% phytonadione, 0.1% retinol and 0.1% vitamins C and E is effective in reducing dark under-eye circles and wrinkles of the lower eyelids. The gel formulation was applied twice daily to the lower eyelid site for 8 weeks. Hemostasis, pigmentation and wrinkles were evaluated by a physician and by the patients after 4 and 8 weeks of treatment. Topical application of the gel decreased not only hemostasis but also wrinkles after 8 weeks of treatment. Of 57 patients, 27 (47%) had reductions in hemostasis. However, pigmentation was not clearly removed by this gel.

Protection and Reversal of Photodamage with Topical Antioxidants

Topical vitamins C and E, as well as topical selenium, protect skin against sunburn, suntan and skin cancer and also reverse the mottled pigmentation and wrinkles of photoaging. However, only certain forms of these antioxidants are stable and active after percutaneous absorption. Benefits of topical application are that the skin attains far higher levels of each antioxidant than can be achieved by taking these vitamins orally and topical application arms the skin with a reservoir of antioxidants that cannot be washed or rubbed off, protecting the skin for several days after application.

Topical application of niacinamide (such as in a 2% cream) has a stabilizing effect on epidermal barrier function, seen as a reduction in transepidermal water loss and an improvement in the moisture content of the horny layer, and it may be used as a treatment adjunct in atopic dermatitis. In aging skin, topical application of niacinamide improves the surface structure and pigmentary disorders, smoothes out wrinkles and inhibits photocarcinogenesis.

Niacinamide can be combined with other active ingredients such as DMAE, sodium hyaluronate, benzoyl peroxide, or metronidazole in a customized medication that can be used as anti-wrinkle or anti-aging therapy or to treat acne or rosacea

Estrogen Therapy to Prevent or Reverse Skin Aging

Declining estrogen levels are associated with a variety of cutaneous changes, many of which can be reversed or improved by topical or systemic estrogen supplementation. Studies of postmenopausal women indicate that estrogen deprivation is associated with declining dermal collagen content, diminished elasticity and skin strength, loss of moisture in the skin, epidermal thinning, atrophy, fine wrinkling, and impaired wound healing. Keratinocytes, Langerhans' cells, melanocytes, sebaceous glands, collagen content and the synthesis of hyaluronic acid are under hormonal influence. Estrogen may attenuate inflammation in psoriatic lesions. Alone or together with progesterone, estrogen prevents or reverses skin atrophy, dryness and wrinkles associated with chronological or photo-aging. Estrogen and progesterone stimulate proliferation of keratinocytes while estrogen suppresses apoptosis and thus prevents epidermal atrophy. Estrogen maintains skin moisture by increasing acid mucopolysaccharide or hyaluronic acid levels in the dermis, and accelerates cutaneous wound healing.

Low estrogen levels that accompany menopause exacerbate the deleterious effects of both intrinsic and environmental aging. Estrogens clearly have a key role in skin aging homeostasis as evidenced by the accelerated decline in skin appearance seen in the perimenopausal years.

At Yale University School of Medicine, the effects of long-term hormone replacement therapy (HRT) on skin rigidity and wrinkling at 11 facial locations was assessed using the Lemperle scale by a plastic surgeon who was blinded to HRT use. Skin rigidity at the cheek and forehead was measured with a durometer. Demographics including age, race, sun exposure, sunscreen use, tobacco use, and skin type were similar. Rigidity was significantly decreased in HRT users compared to nonusers at both the cheek and forehead. Average wrinkle scores were lower in hormone users than in nonhormone users. The study concluded that long-term postmenopausal HRT users have more elastic skin and less severe wrinkling than women who never used HRT, suggesting that hormone therapy may have cosmetic benefits.

In another study, the dermal collagen of 15 postmenopausal women who had received systemic estrogen replacement was analyzed before and after using a topical 0.01% estrogen treatment. Epithelial and dermal thickness improved after topical estrogen therapy. Facial skin collagen significantly increased after 16 weeks of treatment. Systemic estrogen levels did not significantly increase after topical therapy.

The effects of topical 0.01% estradiol and 0.3% estriol compounds were measured in preclimacteric women with skin aging symptoms. After treatment for 6 months, elasticity and firmness of the skin had markedly improved; wrinkle depth and pore sizes had decreased by 61 to 100%; skin moisture had increased; and wrinkle depth decreased significantly.

A low-dose, topical gel form of diclofenac sodium has been developed in Europe for pain relief and reduction of redness after sunburn.

TOPICAL ANESTHETICS

Topical anesthesia is needed for common procedures such as suturing, wound cleaning, and injection administration. The ideal topical anesthetic would provide complete anesthesia following a simple pain-free application, not contain narcotics or controlled substances, and have an excellent safety profile. The combination of topical anesthetics lidocaine and tetracaine and the vasoconstrictor epinephrine has been used successfully for anesthesia prior to suturing linear scalp and facial lacerations in children. A triple-anesthetic gel containing benzocaine, lidocaine, and tetracaine ("BLT") has also been reported to be effective when applied prior to laser and cosmetic procedures. Convenience of application without need for occlusion is an advantage of these topical anesthetics.

The following article concludes: "LAT gel (4% lidocaine, 1:2000 adrenaline, 0.5% tetracaine) worked as well as TAC gel (0.5% tetracaine, 1:2000 adrenaline, 11.8% cocaine) for topical anesthesia in facial and scalp lacerations. Considering the advantages of a noncontrolled substance and less expense, LAT gel appears to be better suited than TAC gel for topical anesthesia in laceration repair in children."

The following article reported that a triple-anesthetic gel containing benzocaine, lidocaine, and tetracaine ("BLT") applied prior to treatment with a 532-nm KTP laser resulted in significantly lower pain scores than with 3 other topical anesthetics at 15, 30, 45, and 60 minutes after application.

Topical piroxicam 0.5% gel was associated with fewer inflammatory side effects than was EMLA cream, because of its anti-inflammatory effect after the procedure.

PLANTAR WARTS

The primary objective of a current multicenter, randomized controlled trial conducted by the Department of Health Sciences, University of York, UK is to compare the clinical effectiveness of two common treatments for verrucae: cryotherapy using liquid nitrogen versus salicylic acid. The primary outcome is complete clearance of all verrucae as observed on digital photographs taken at 12 weeks.

Topical 5-fluorouracil (5-FU) 5% with tape occlusion produced complete eradication of all plantar warts within 12 weeks of treatment in 19 of 20 patients. It was concluded that use of topical 5% 5-fluorouracil cream for plantar warts is safe, efficacious, and accepted by the patient.

A medical record review was conducted by the Podiatry Division, Department of Orthopedics, Cabrini Medical Center, New York, NY to determine the clinical outcome and average time to resolution of verruca plantaris (plantar warts) in 20 patients treated with twice-daily applications of topical fluorouracil (5-FU) combined with topical 17% and 40% salicylic acid. Twice-daily application of topical fluorouracil and salicylic acid is a safe and effective treatment for verruca plantaris.

Therapy with 10% KOH was found to be effective and safe in the treatment of molluscum contagiosum (MC) in children, although a stinging sensation was reported by most children during the trial and some developed hyper- or hypopigmentation after treatment at the site of the lesions.

In an attempt to reduce the side effects (stinging sensation & hyper- or hypopigmentation) found with use of 10% KOH, a new trial of 20 children used a less concentrated KOH solution (5%) for treatment of molluscum contagiosum (MC). The 5% KOH aqueous solution proved to be as effective as and less irritating than 10% KOH, and spared children from more aggressive physical modalities of treatment.

These studies showed that 5% imiquimod cream and 10% KOH solution are equally effective in treating molluscum contagiosum, although KOH has a faster onset of action.

Cantharidin in a collodion vehicle has been used by dermatologists as a treatment for molluscum contagiosum and warts since the 1950s. Cantharidin lost FDA approval in 1962 because its manufacturers failed to submit data attesting to cantharidin's efficacy. However, in 1999, the FDA included cantharidin on its "Bulk Substances List" of drugs which although not available as commercial products, were approved for compounding on a customized basis for individual patients.

Because of cantharidin's potential for toxicity, the FDA has proposed that cantharidin should be limited to "topical use in the professional office setting only." Severe blistering can result from improper use, and ingestion, especially by children, can be fatal. Treatment of mucous membranes is contraindicated and placement of cantharidin near the eyes and eyelids should be avoided to prevent scleral erosion.

Caution: The treatment of plantar warts with cantharidin is NOT recommended and may have a higher rate of significant complications including lymphangitis and refractory lymphedema.

Squaric Acid Dibutylester (SADBE) for Cutaneous Warts in Children

Warts are a common pediatric skin infection and clearance may be enhanced by contact sensitizers, such as squaric acid dibutylester (SADBE). Contact immunotherapy with SADBE is relatively safe and an effective alternative in the management of multiple and resistant cutaneous warts in children.

PIGMENTATION ABNORMALITIES

Grimes et al of the Division of Dermatology, University of California, Los Angeles, sought to determine the efficacy and safety of continuous therapy followed by a maintenance treatment regimen during a period of 24 weeks with a TC cream containing hydroquinone 4%, tretinoin 0.05%, and fluocinolone acetonide 0.01%. The study concluded that TC cream is safe in the treatment of moderate to severe melasma for up to 24 weeks when used intermittently or continuously.

The purpose of this study was to evaluate the efficacy of trichloroacetic acid as well as glycolic acid associated with kojic acid in the treatment of cutaneous hyperpigmentations. This study concludes that both peelings can be considered effective.

Patients with vitiligo have low catalase levels in their epidermis in association with high levels of hydrogen peroxide. Topical application of a UVB-activated pseudocatalase cream can successfully remove epidermal H2O2 resulting in a remarkable repigmentation.

Researchers concluded that "although hydroquinone showed a better response, ascorbic acid may play a role in the therapy of melasma as it is almost devoid of side-effects; it could be used alone or in combination therapy."

Melasma is a circumscribed brown macular hyperpigmentation of areas of the face and neck that are exposed to light, and is aggravated by sunlight, birth control pills, and pregnancy. This study demonstrates that a cream containing hydroquinone, glycolic acid, vitamins C and E, and sunscreen is a safe and effective treatment therapy for melasma.

The antioxidant N-acetyl cysteine (NAC) has an antiproliferative effect on human keratinocytes and NAC has been used topically to satisfactorily treat lamellar ichthyosis.

Topically applied NAC can prevent skin irritation resulting from radiotherapy and protects from sun-induced erythema.

NAIL INFECTION/REMOVAL

Treatment of Fingernail Lichen Planus

Nail lichen planus most commonly occurs during the fifth and sixth decade of life and can be notoriously recalcitrant to many forms of treatment. Prevost and English of the University of Pittsburgh Department of Dermatology reported a case of successful treatment of destructive inflammatory lichen planus of the nails with combined topical therapy of tazarotene gel and clobetasol gel, without the occurrence of potential adverse affects of systemic treatments.

Although surgical excision is the most popular method for removing nails, the use of concentrated urea plasters applied under occlusion may be superior. The use of urea plasters has inherent advantages - they are inexpensive, several nails can be treated in one session, and the procedure is essentially painless. Various synergistic combinations and topical medications with penetrant enhancers can be compounded for antifungal therapy. Topical medications usually have a lower adverse drug-reaction profile than systemic medications.

Management of onychomycosis, a fungal infection of the fingernails and toenails, usually consists of systemic antifungal medications, topical therapy (e.g., urea ointment, desiccating solutions, keratolytics, vital dyes), or surgical intervention (e.g., nail plate avulsion, laser therapy). Topical prescription antifungal preparations, containing the active ingredient of your choice, may be less likely to cause the serious systemic side effects that can occur with oral antifungal therapy and can provide a more economical alternative, as lower doses are needed when the medication is applied topically at the site. Penetrant enhancers can be included in the preparation to improve the effectiveness of topical antifungals.

MOLLUSCUM CONTAGIOSUM

Resistant warts and molluscum contagiosum have been treated successfully with compounded topical medications, avoiding discomfort associated with freezing, scraping, electrocautery and laser therapy.

Therapy with 10% KOH was found to be effective and safe in the treatment of molluscum contagiosum (MC) in children, although a stinging sensation was reported by most children during the trial and some developed hyper- or hypopigmentation after treatment at the site of the lesions.

In an attempt to reduce the side effects (stinging sensation & hyper- or hypopigmentation) found with use of 10% KOH, a new trial of 20 children used a less concentrated KOH solution (5%) for treatment of molluscum contagiosum (MC). The 5% KOH aqueous solution proved to be as effective as and less irritating than 10% KOH, and spared children from more aggressive physical modalities of treatment.

Studies showed that 5% imiquimod cream and 10% KOH solution are equally effective in treating molluscum contagiosum, although KOH has a faster onset of action.

HEAD LICE AND SCABIES

Concerns about emerging resistance and the potential harm of using permethrins have prompted a search for effective pediculicidal therapies that are not harmful to children with repeated use. An herbal formulation has been shown to be effective for head lice. Ivermectin can also be compounded for topical application or as an oral dose titrated for each patient for the treatment of head lice and scabies.

Twenty six male and female patients aged 5 to 17 years had head lice infestation confirmed by eggs presence and received treatments with a single 200 microgram/kg oral dose of. At day 14 after treatment, 20 had responded to the treatment (77%), and 6 patients (23%) presented with a complete disappearance of eggs and all clinical symptoms. At day 28, 7 patients appeared clear of infestation (27%), but 4 of the 6 patients with no eggs at day 14 presented with signs of reinfestation. This study suggests that ivermectin is a promising treatment of head lice, and a second dose at day 10 may be appropriate.

Two hundred scabies patients were randomly allocated to receive either oral ivermectin in a single dose of 200 micrograms/kg body weight, or 1% lindane lotion for topical application overnight. Patients were assessed after 48 hours, two weeks and four weeks. After a period of four weeks, 82.6% of the patients in the ivermectin group showed marked improvement; only 44.44% of the patients in the lindane group showed a similar response. Oral ivermectin is easy to administer as a single oral dose, induces an early and effective improvement in signs and symptoms, and compliance is accordingly increased.

CHEMICAL PEELS

Chemical peelings with kojic acid, glycolic acid, and trichloroacetic acid, either alone or in combination, are effective therapy for diffuse melasma and localized hyperpigmentations (lentigo).

The purpose of this study was to evaluate the efficacy of trichloroacetic acid as well as glycolic acid associated with kojic acid in the treatment of cutaneous hyperpigmentations. This study concludes that both peelings can be considered effective.

A cream containing 4% hydroquinone, 10% buffered glycolic acid, vitamins C and E, and sunscreen is safe and effective in the treatment of melasma.

Although hydroquinone showed a better response, ascorbic acid may play a role in the therapy of melasma as it is almost devoid of side-effects; it could be used alone or in combination therapy.

ATHLETE'S FOOT

Various synergistic combinations are used for antifungal therapy. Research points to the practicality "of using ibuprofen, alone or in combination with azoles, in the treatment of candidosis, particularly when applied topically, taking advantage of the drug's antifungal and anti-inflammatory properties."

ACNE

We can compound customized formulations which contain numerous medications to provide a synergistic effect for treatment of resistant acne.

VITILIGO

Treatment Options for Vitiligo

Pseudocatalase Cream

Vitiligo is a spontaneous irregular depigmentation of skin. Patients with vitiligo have low catalase levels in their epidermis with high levels of hydrogen peroxide. Pseudocatalase cream is an externally applied UVB-activated product that can lead to recovery of the oxidative damage in the epidermis and remarkable repigmentation.

Topical Phenylalanine

Melanocytes may still be present in long-standing (>25 years) depigmented skin of patients with vitiligo. L-phenylalanine uptake and turnover in the pigment forming melanocytes is vital for initiation of melanogenesis. Phenylalanine hydroxylase activities increase linearly with inherited skin color yielding eightfold more activities in black skin compared to white skin.

Camacho and Mazuecos performed an uncontrolled retrospective survey of a group of 193 patients (171 participants after screening) with evolving vitiligo who were treated with oral (50 or 100 mg/kg daily) and topical (10% gel) phenylalanine plus sun exposure . When the study closed, 100% repigmentation was achieved in 122 patients on the face, 35 on the trunk, and 33 on the limbs. Patients who were treated during the months of high solar radiation (and therefore also used the topical phenylalanine) achieved greater repigmentation. No side effects were reported.
