what does collagen do for your skin
1) Skin Health. Some studies have found that collagen peptides can improve skin elasticity. In a 2014 study in Skin Pharmacology and Physiology, for instance, women aged 35 to 55 years took collagen supplements or a placebo once daily for eight weeks.
There are at least 16 types of collagen, but 80-90% of the collagen in the body consists of types I, II, and III. Type I collagen fibrils are stronger than steel (gram for gram). Collagen is most commonly found within the body in the skin, bones and connective tissues. The word collagen is derived from the Greek kolla, meaning glue. Collagen gives the skin its strength and structure, and also plays a role in the replacement of dead skin cells.
