Collagen

Collagen is a protein that is a critical component of skin’s extracellular matrix, or ECM. It is the most abundant protein in the human body. Collagen provides structure and support for skin’s basic architecture, in addition to defining cell behaviors and tissue function. Collagen depletion – either through the natural process of growing older or repeated environmental assault – is one of the key factors leading to signs of visible ageing.

When applied directly to skin, collagen’s largest benefit is as a humectant, binding water to help skin retain moisture. It does not, however, build new collagen. Its high molecular weight means it isn’t able to penetrate skin, and beneath the surface is where it would work optimally to restore skin firmness.

However, this doesn’t mean you can’t promote collagen! There are other ingredients, among them key targeted peptides, that help to restore collagen within skin, improving the look and feel of firmness.
