The occurrence of skin spots is due to an uneven production of melanin. Melanin develops from an amino acid, tyrosine, through the action of an enzyme, tyrosinase. In normal conditions, the process of epidermal regeneration allows the darkened skin to return spontaneously to its original color once the stimulus that induced the production of melanin is over. However, the production can sometimes be excessive and continuous, thus giving rise to melain stains. This formulation was designed to act by blocking the tyrosinase enzyme: the results are supported by effectiveness testing on differently origined blemishes like solar lentigo, freckles, dyschromia and pregnancy chloasma. It is both effective on dyschromia and localized skin spots such as chloasma, melasma, sun spots and Postinflammatory Hyperpigmentation.
