These “mini-proteins” are active molecules which increase the thickness of the skin by stimulating collagen production, or replacing collagen you’ve lost as a result of aging. Collagen is what gives youthful skin its plump, taught appearance. As we age collagen production slows down, so if we use signaling peptides to tell the skin to make more collagen, our skin acts younger, and wrinkles are lessened. Some peptides (neuropeptides) block the signal from the nerve to facial muscles, and have a relaxing effect on the muscle. This results in temporary smoothing effects, similar to Botox®.
