Products containing peptides have been used for centuries in facial and body care. There is good reason for the many legends telling of the positive effects of such products on the skin. It is now known that the principal agents responsible for this famous skin care effect are bioactive peptides, wherein tripeptides are one of the main active ingredients.
However, despite their potential skin care properties other currently available peptides for cosmetic products may have the disadvantage of: instability of cosmetic formulation, high price for synthetically manufactured peptides and the lack of scientifically proven effectiveness.
