Benefits of Collagen for SkinWhile collagen is beneficial to the entire body, it is most noticeably beneficial to the skin. This is because as a person ages, 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! (3)
Even more exciting:
Additionally, after 8 weeks of intake a statistically significantly higher content of procollagen type I (65%) and elastin (18%) in the BCP-treated volunteers compared to the placebo-treated patients was detected.
This means that supplemental collagen appears to help the body’s own production process improve, as procollagen is the precursor to collagen in the body.
This study also showed that collagen consumption can increase skin elasticity and moisture, which also declines during the aging process.
It is important to note that this study used the hydrolyzed (peptide) form (the blue lid), which is a more easily digestible form of collagen. I’m not aware of any studies that directly compare gelatin and collagen for their ability to improve skin, so for skin health, I use the peptide form.
