Bioactive collagen peptides in Colway and Colway International cosmetics are peptides obtained from fish skin (Fish - Scale Collagen Peptides - FSCP), which are an ideal source of collagen. Collagen is a key ingredient in maintaining skin elasticity, and reducing its content causes wrinkles and sagging skin.
The callous layer of the epidermis acts as a physical barrier for many cosmetic ingredients, so their action is limited only to the upper layers of the skin. In the case of FSCP peptides, studies have shown that they penetrate the keratinized layer of the epidermis into its deeper layers and further - into the dermis. FSCPs in the epidermis and dermis are able to activate fibroblasts and accelerate collagen synthesis, thus significantly improving skin characteristics such as hydration and relative elasticity.
