Collagen Extract Best Humectant Anti-Ageing Hydration Collagen Extract at a glance Usually animal-derived Cannot penetrate skin’s surface and cannot promote collagen production Helps prevent water loss and promote hydration In cosmetics, is also used as a texture enhancer Collagen Extract description Collagen extract is collagen (a type of protein that provides structure and support for skin’s architecture) that is usually derived from tendon, skin, cartilage and bone of animals. When it is used in cosmetics, it goes through a purification process to ensure the end product is simply collagen. Though internally collagen is tasked with maintaining skin’s firmness and elasticity, when applied topically it does not have the same benefit (not even close). This is due to collagen extract’s large molecular weight, which prevents it from penetrating skin’s surface to impact the fibroblasts beneath. This does not mean that collagen extract isn’t skin-beneficial when used in cosmetics. It still functions as an effective humectant, preventing trans-epidermal water loss (TEWL), leaving skin looking refreshed, hydrated, and more supple. Collagen extract is also used as a texture enhancer in some cosmetics preparations. Use levels range from 0.5–5%, depending on the desired formulary goals.
