Probably not — at least not the way the tub implies. The largest recent review of the evidence found that once you set aside the low-quality and industry-funded trials, oral collagen showed no measurable effect on skin aging. The levers that hold up are less interesting: daily sun protection and a topical retinoid.
TL;DR
A 2025 meta-analysis in The American Journal of Medicine pooled 23 randomized controlled trials and concluded there is currently no clinical evidence that collagen supplements prevent or treat skin aging. The positive results clustered in the lower-quality, industry-funded studies. Collagen is also digested into amino acids before it is absorbed, so swallowing it does not deliver collagen to your face.
What does collagen actually do in your skin?
Collagen is the structural protein that gives skin its firmness. It sits in the dermis, the layer beneath the surface, woven together with elastin. Your body produces less of it as you age, and UV exposure accelerates the breakdown — which is why the side of your face that faces the car window tends to age faster than skin you keep covered. Less collagen means thinner, looser skin and lines that stay put after your face relaxes.
Does swallowing collagen put collagen in your face?
No. Collagen is a protein, and digestion breaks proteins down into amino acids and short peptides before anything crosses into your bloodstream. As the dermatologists reviewing this evidence have pointed out, collagen has to be broken down to be absorbed, so consuming it does not actually deliver collagen to the tissue that needs it. Your body allocates those amino acids wherever it wants; none of them arrive labeled "face."
What did the research actually find?
The 2025 meta-analysis by Myung and Park looked at 23 randomized controlled trials covering about 1,474 people. The initial pooled numbers looked encouraging — improvements in hydration, elasticity, and wrinkle scores. Then the authors sorted the trials by quality. The high-quality studies showed no significant effect in any category; the improvements came entirely from the low-quality ones.
Why do so many collagen studies look positive?
Because of who paid for them. The analysis found that industry-funded trials tended to report benefits while independently funded trials did not, and that the industry-backed studies were more likely to be methodologically weak. That matters here because most claims on a supplement label trace back to one of those trials. Supplement makers have pushed back, arguing that "collagen" covers a wide range of ingredients and doses — a fair point, and an unresolved one.
So what routine actually supports aging skin?
The unglamorous answer is sun protection plus a retinoid, applied consistently for years. Sunscreen is the single most effective anti-aging step because it slows the UV-driven collagen breakdown that is doing most of the visible damage; a morning moisturizer with SPF, like Tiege Hanley's AM at SPF 20, makes that a one-step habit rather than a separate product you forget. Retinoids are the other well-supported category, and SUPER SERUM carries a retinoid in the form of retinyl palmitate alongside peptides and sodium hyaluronate. If you want the longer explanation of why that ingredient class earns its reputation, we covered how retinol works for men separately, and what peptides do for your skin is worth reading if you are comparing topical options to a powder.
Putting those pieces together on your own is where most guys stall. Level 3: The Anti-Aging Routine bundles them — cleanser, scrub, the SPF 20 morning moisturizer, night moisturizer, eye cream, and SUPER SERUM — so the two steps with evidence behind them are already in the lineup and in the right order. It is a slower payoff than a scoop of powder in your coffee, which is rather the point.
Is there any reason to take collagen anyway?
Possibly, as a protein source. Adequate protein supplies the raw materials your body uses to build connective tissue, and collagen powder is protein. The caveats are that supplements are not reviewed for safety before they reach shelves, most oral collagen products lack third-party verification or clear ingredient disclosure, and marine-sourced versions carry some risk of methylmercury contamination. If you enjoy it and it fits your budget, it is unlikely to hurt you — just do not treat it as a substitute for the two steps above.
Frequently asked questions
How long would collagen take to work if it did work?
Most trials ran 8 to 12 weeks, which is the standard window for seeing measurable change in skin hydration or elasticity. If you have been taking it for three months and nothing has changed, more time is unlikely to be the missing variable.
Is topical collagen better than oral collagen?
Not really, for a different reason. Collagen molecules are generally too large to penetrate the outer layer of skin, so topical collagen mostly acts as a surface moisturizer. Ingredients that are proven to influence collagen in the dermis, such as retinoids, work by signaling your own cells rather than by supplying the protein directly.
Do vitamin C and protein matter for collagen production?
Yes, in the sense that your body cannot build collagen without them. Vitamin C is a required cofactor in collagen synthesis and protein supplies the amino acids. That is an argument for eating reasonably, not an argument that extra amounts will push production above normal.
What single change makes the biggest difference to how my skin ages?
Wearing broad-spectrum SPF every morning, including on overcast days and days you expect to be indoors. UV exposure drives the majority of visible skin aging, and it is the one variable you fully control.
Should I stop taking collagen?
That is your call, and worth raising with your doctor if you take it for joints. The evidence for skin benefits is weak, but the supplement is low-risk for most healthy adults. The practical move is to stop expecting it to do the job sunscreen and a retinoid do.
