A Holistic Nutritionist On How She Approaches Collagen Support 

Recently I was discussing the emerging field of regenerative dermatology with two women in the space: board-certified dermatologist Julie Russak, M.D., and board-certified holistic nutritionist Jennifer Hanway. (Tune in to the convo here.)

Regenerative dermatology—and the ethos beyond their practice—focuses on how to restore vitality to the body and skin at the cellular level, using the latest and greatest research on whole-body health. And to do so, there's not a one-size-fits-all approach—nor is there one modality that will magically fix skin concerns. 

It's about how products, nutrition, lifestyle, and even in-office treatments work together for a better outcome. One such example we discussed was collagen. Collagen is a structural protein in the skin that gives it firmness and lift.

Like most things in the body, it declines with age (as well as due to things like UV exposure, diet, and lifestyle habits). And this loss contributes to fine lines, sagginess, and textural issues. 

Treating something holistically isn't just for feel-good vibes: There's an art and science to it. The gist is that you can't properly treat a concern by addressing one singular pathway if other parts of the system aren't functioning properly. 

"[You can use topicals and treatments] to stimulate collagen production in the skin, but if you're inflamed, then you're not going to be able to regenerate that collagen," says Hanway.

"Or if you have too much sugar in the diet, any collagen that's getting regenerated is just going to get broken down again. Or if the gut health is impaired, then you're not going to have those raw materials. Finally, if you're not putting in those raw materials—like amino acids—then you have nothing to build with."

You can't just apply a serum to aggravated skin and hope for the best—you need to find the root cause of the inflammation, which can be from stress, too strong of beauty products, environmental aggressors, or diet.

Similarly, your body can only produce what it has building blocks for. Amino acids, for example, are the building blocks of collagen and elastin.
