Can we apply Collagen skin care products on face? The answer is no.
Collagen is an insoluble, fibrous protein that is too large a molecule to penetrate the skin. No matter how much is present in a cosmetic, it WILL NOT GET INTO YOUR SKIN.
The collagen found in most skin care products is derived from animal skins and ground-up chicken feet! Whilst it is a major body component, the form used in cosmetics is foreign and does not even get absorbed through the skin, much less help "rebuild it" as some products claim. When applied to the skin, most collagen products form a film layer, which can stop oxygen transport, suffocating the skin.
