L-Phenylalanine has demonstrated its effectiveness, not just in treating vitiligo, but also in other cases of hypopigmentation caused by burns, traumas or skin diseases such as pityriasis alba, tinea versicolor, and post-inflammatory hypomelanosis, generally caused by inflammatory dermatosis (psoriasis, atopic dermatitis, etc).
L-Phenylalanine is an essential amino acid in the production of melanin. Our bodies cannot produce it alone, which is why administration directly to the skin (Fenadul Gel) and orally (Fenadul Capsules) will effectively enhance melanin production.
Speeding up the repigmentation of depigmented areas will be reinforced if we combine L-Phenylalanine with sun exposure or UVB phototherapy. At Abedul Productos Farmacéuticos we market a UVB-nb phototherapy lamp for use in the home, which comes with a handbook explaining the different exposure times depending on the phototype of the skin.
Administering L-Phenylalanine increases tolerance of hypopigmented areas (more sensitive to burns) to sun exposure, allowing the skin to tan correctly.
Phenylalanine inhibits the production of antibodies against melanocytes, and activates melanocytes that have altered with sun radiation, stimulating the production of melanocytes from pigmented areas to depigmented areas.
For optimum results, take the oral supplement (Fenadul capsules) 45 minutes before sun exposure, and apply the gel (Fenadul Gel) 30 minutes before, massaging the depigmented area until it is fully absorbed.
The use of Fenadul is not recommended during pregnancy, breastfeeding, or in the case of kidney failure, liver failure or phenylketonuria, as well as in patients with a history of skin cancer or undergoing radiotherapy treatment.
