It is often derived from fish or bovine sources and works as a nice moisturizer and humectant that helps the skin to hold onto water. To understand a bit more what Hydrolyzed Collagen is, you have to know that proteins are large chains of amino acids connected with so-called peptide bonds. These bonds can be broken up when a water molecule is added and the resulting thing is a mix of shorter length amino acids, also called peptides. So Hydrolyzed Collagen is not really collagen, it is rather an undefined and varying mix of largish peptides. Based on a manufacturer's data, the whole, soluble collagen has an average molecular weight of 300 000 Da, while this chopped up mixture has an average MW of 12 000 Da (still pretty big). Expand to read more The main thing of these largish peptides is to act as water-binding agents, and to make the skin nice and smooth (aka emollient). Hydrolyzed Collagen is also often used in cleansers as it can make harsh surfactants milder and in hair conditioners as it improves the flexibility and manageability of hair. If you wanna know more about collagen in cosmetics, we have a shiny explanation about soluble collagen here >> It's a sweet tasting sugar substitute that helps your skin to hold onto water when used in cosmetic products. It also helps to thicken up products and give them a bit more slip. Works best between a concentration of 5-20% Boosts the skin’s own collagen production Fades pigmentation and brown spots If used under sunscreen it boosts its UV protection Extremely unstable and oxidizes very easily in presence of light or air Stable in solutions with water only if pH is less than 3.5 or in waterless formulations Vit E + C work in synergy and provide superb photoprotection Ferulic acid doubles the photoprotection effect of Vit C+E and helps to stabilize Vit C Potent Vit. C serums might cause a slight tingling on sensitive skin It’s the - sodium form - cousin of the famous NMF, hyaluronic acid (HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here. The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water. As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephen writes on reddit "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution". In spite of this, if you search for "hyaluronic acid vs sodium hyaluronate" you will find on multiple places that sodium hyaluronate is smaller and can penetrate the skin better. Chemically, this is definitely not true, as the two forms are almost the same, both are polymers and th what‑it‑does emollient | moisturizer/humectant moisturizer/humectant irritancy, com. antioxidant | skin brightening | buffering skin-identical ingredient | moisturizer/humectant
