So I’ve been binge watching Married At First Sight as a pandemic coping mechanism, and one thing stands out to me: all of the beefy newly-wed dudes on that show seem to have big old canisters of collagen peptides on top of their fridge. It got me thinking: what exactly is a collagen peptide, and does consuming it help you achieve the aesthetics of an Athenian god?
Of course, as someone who writes about all-things-skincare, I’m familiar with all of the popular myths about collagen-infused products. I’ve heard it before: collagen plays a role in our body beyond our skin, so adding an extra serving to your diet supposedly has all sorts of health benefits.
I hate to break it to you, but here’s the truth: even though collagen supplements are a go-to dietary supplement for many, we don’t know if they have any benefits for your skin — we need more research first. But here’s what we know so far.
Collagen is the protein that helps give our body structure. With its fellow protein, elastin, it gives our skin its, well, elasticity. In the skin, it helps maintain strength and firmness. And it’s the most plentiful protein in our body, helping to build and connect our bodies (bones included).
Peptides and proteins are both made up of the same building blocks: amino acids. The difference between them is that a peptide contains up to 50 amino acids while a protein has 50 or more.
Collagen peptides (also known as hydrolyzed collagen) are essentially broken down pieces of collagen proteins. They’re often sold as a powder-based dietary supplement that you can mix into whatever you’re already drinking — or eating! (Collagen peptide soup, anyone?)
Does eating more collagen = younger looking skin? We don’t know for certain — yet.
In 2018, a double-blind, placebo-controlled study on edible collagen found that it can potentially be used to improve “skin hydration, elasticity, and wrinkling.” But you don’t need to buy a special supplement to get the benefits of oral collagen! You can also get collagen from eating protein-rich foods (think meats, cheese, eggs, and beans).
That said? The collagen in our bodies gradually breaks down over time. And we can only control some of the causes for this breakdown. It’s like I always say: reverse aging isn’t truly possible unless you have a time machine.
Eating collagen can only do so much — it gets broken down by the digestive system into individual amino acids, which then get absorbed into the rest of our body. In other words, collagen peptides might not do more than eating an extra helping of beans.
If you think you’d benefit from an extra helping of collagen, talk to your in-person medical provider about what makes sense for you!
Even though you can eat collagen it might be more beneficial to try to stimulate collagen production through topicals. But — irony! — topical collagen isn’t really an effective skincare ingredient. Collagen molecules in skincare products are far too large to be absorbed into the skin, so topical collagen products are likely of no benefit.
Instead, be sure to practice sun safety to help protect your skin from UV damage, which can lead to collagen loss and signs of premature aging. Also, seek out skincare products with these collagen-stimulating ingredients:
Vitamin C treats firmness and wrinkles by acting as a shield against aging. It also promotes collagen growth, fights wrinkles, and helps clean up the damage from UV rays.
Vitamin C is a great option if you’re building your skincare routine with fully over-the-counter products (as opposed to ones prescribed by your dermatology provider). I use a vitamin C serum, since I can just add a couple drops to my SPF to get the antioxidant benefits my skin craves.
Tretinoin is a prescription-strength retinoid that’s often considered the gold standard in stimulating collagen production, treating and helping prevent wrinkles, and even clearing up acne. It’s only available through a prescription, but if you can’t get to an in-person doctor, teledermatology is an option!
