While collagen is beneficial to the entire body, it is most noticeably beneficial to the skin. This is because as a person age, the epidermic (outer layer of skin) thins and loses elasticity in a process known as elastosis. As this happens, a person tends to show more signs of aging and acquire more wrinkles.
The good news is that these changes do not seem to be permanent or irreversible. In fact, a double-blind placebo study conducted last year found that women who took collagen hydrolysate (the peptide form) regularly for 8 weeks saw a 20% reduction in wrinkles!.*
