A cocktail of active ingredients acting in synergy, in order to "brighten" the skin and create a uniform colour. The cocktail includes 3 biomimetic peptides (Oligopeptide-34, -51, -58), vitamin C (AA2G) and a-Arbutin. The peptides act as messengers. This is accomplished by their binding to specific cell receptors, in order to provide the orders for the performance of processes. Specifically, Oligopeptide-34 reduces the formation of melanin, the action of tyrosinase in melanocytes, as well as the transfer of melanosomes to new keratinocytes. Oligopeptide-51 'decolourises' freckles and spots, increases the levels of moisture and forms a uniform skin tone. Oligopeptide-58 protects skin from the sun, reduces spots and uniformly "brightens" the skin. In addition, Οligopeptide-34 & -51 act as 'boosters' enhancing the overall activity of the cocktail. The action of the peptides is enhanced by the presence of AA2G, which contributes to the suppression of melanin formation in melanocytes, as it degrades the existing granules and inhibits the formation of new melanin granules to the skin. Finally, a-Arbutin 'blocks' the biosynthesis of melanin in epidermis, offering uniformity of the skin tone and locally reducing freckles and spots.
