Unipertan

Active ingredient in many tanning accelerators composed of tyrosine, protein, riboflavin and adenosine triphosphate (ATP). The body converts tyrosine to melanin, ATP assists in the conversion, and the protein aids in the products absorption. Unipertan formulations contain either animal proteins (P-24) or vegetable proteins (VEG-242). Its efficacy is based on the assumption that the tyrosine is able to penetrate the skin, which has not been convincingly demonstrated. However the absorption of UV rays is enhanced when the skin is moist.
