Fenadul capsules help you regenerate the spots caused by vitiligo by repigmenting the skin. Taking care of depigmented skin should be done both externally, with specific topical preparations, and internally, through the intake of food supplements that complete a varied diet. The Fenadul Line has oral and topical photosensitizing products that provide depigmented skin with the essential amino acid L-Phenylalanine, essential in the treatment of vitiligo. L-Phenylalanine is one of the components necessary in the phases of melanin formation. An extra contribution of this component in people who have skin pigmentation problems can encourage melanocytes to generate more pigment. It can be used for the treatment of vitiligo combined with both natural and artificial sun exposure (ultraviolet rays). Phenylalanine is not phototoxic, has no important side effects and induces tolerance to sun exposure in depigmented areas that usually tend to burn, therefore allowing its use in pediatric age.
