Fenadul gel helps reduce vitiligo spots by repigmenting the affected areas. Depigmented skin should be cared for both externally, with specific topical preparations, and internally, through the intake of dietary supplements that complement a varied diet. The Fenadul line includes oral and topical photosensitizing products that provide depigmented skin with the essential amino acid L-Phenylalanine, which is essential in the treatment of vitiligo. L-Phenylalanine is one of the components necessary for the formation of melanin. An extra dose of this component can help people with skin pigmentation problems increase the production of melanocytes. It can be used for the treatment of vitiligo combined with both natural sun exposure and artificial exposure through home phototherapy treatments (ultraviolet rays). Fenadul Gel provides the skin with L-Phenylalanine, which helps accelerate tanning.
