Collagen powders are made of hydrolyzed collagen peptides, which are basically just short-chain amino acids. These are small enough to actually be absorbed by the body (collagen itself is too large of a molecule to be absorbed, which is why powders are hydrolyzed and therefore digestible). Once in the body, these peptides have been shown to promote, support, and maintain your skin cells’ fibroblasts.* Fibroblasts are actually the parts of your skin cells that produce collagen and elastin.
OK, translation? Healthy fibroblasts mean healthy collagen levels. This all matters for dermal density because collagen is the main structural protein in the skin. And if you are better able to maintain your collagen levels, which unfortunately decline significantly as we age, then you can improve your skin barrier function. In fact, research shows that taking collagen supplements can support dermal density.*
In mindbodygreen’s grass-fed collagen+, however, you also have loads of antioxidants to better support your skin and protect it from free radical damage. First, there’s vitamin C, which has been shown to help collagen production synthesis, stabilize the collagen you already have, and, of course, protect skin from environmental aggressors like UV or pollution.* (It also comes formulated with vitamin E to help maintain the former antioxidant’s efficacy.)
Finally, there’s hyaluronic acid. This is actually naturally present in the body—it, too, starts to decline with age. Its main role is to hold in moisture in the skin, as a naturally occurring humectant.* Since dermal thickness is closely related to hydration, keeping skin hydrated is also of the utmost importance.*
