Soluble collagen is a large, water-loving protein typically extracted from cattle hides or marine sources like fish skin. In cosmetics, it works purely as a humectant and film-former. Despite the marketing that surrounds the word "collagen", its molecule is far too large to penetrate skin so it can't rebuild the collagen in your dermis. Instead, it sits on the surface and binds water to help reduce transepidermal water loss and leave skin feeling soft, plump, and temporarily tightened. Suppliers commonly recommend using it around 3-6% though industry data shows concentrations are often much lower (down to a fraction of a percent). This ingredient has been found safe to use in cosmetics with no reported irritation, sensitization, or phototoxicity. Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation. You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
