Collagen has surged in popularity in the skincare world over the past several years thanks to its ability to support healthy hair, skin and nails. Research suggests that when the body has more collagen, skin can look and feel smoother, bouncier and more youthful, so collagen masks have become a staple in many age-supporting beauty routines.
“Collagen is the most abundant protein in the body,” says board-certified dermatologist Dr Rina Allawh. “It’s responsible for keeping skin strong and firm and plays an important role in wound healing.”
The body gradually produces less collagen with age and skin reflects that change. Dr Allawh explains that after around age 20, the skin produces about 1% less collagen each year. More noticeable changes often appear in the 30s and 40s, when fine lines and wrinkles begin to show.
Because of this, many people choose to add collagen to their diet or skincare routine, including in mask form. Collagen helps skin hold on to water and stay moisturised, giving it a smoother, plumper appearance, Dr Allawh adds. That makes a collagen-infused hydration mask sound promising.
But does applying collagen on the surface of the skin really prompt it to make more of this essential protein? Dermatologists weigh in.
What are collagen masks, exactly?
Collagen masks are creams, gels or sheet masks applied to the face that include collagen as one of the key ingredients. They are left on the skin for a set amount of time so the formula can sit on the surface and hydrate. The aim is to support smoother, bouncier-looking skin and soften the appearance of lines, wrinkles and sagging.
When collagen is applied topically via a mask, the big question is how well it can move beyond the very top layer of skin. “The concern is whether or not the collagen protein will penetrate the top layer of skin,” Dr Allawh says. For that reason, she recommends looking for products that list hydrolysed collagen or collagen amino acids, which are more likely to be absorbed. If a product simply lists “collagen” on the label, it may contain larger molecules that are less able to sink into the skin.
Hydrolysed collagen is collagen that has been broken down into smaller chains of amino acids, so it can be taken up more easily by the upper layers of skin. It also acts as an antioxidant, notes a 2020 review.
As the skin soaks up these amino acids, the aim is to give the skin the building blocks it needs for collagen production. “There isn’t a lot of great data out there in the scientific literature about how effective collagen masks are. We know hydrolysed collagen can penetrate the upper layers of skin to stimulate new collagen in skin, but we still need more studies that analyse how effective this is,” Dr Allawh says.
One small study of 60 middle-aged women, found that those who applied a topical hydrolysed collagen product for one month had higher skin moisture levels and better elasticity than those using a placebo. Another group in the same study consumed oral collagen and, after 90 days, had a reduction in pore size. These results are encouraging, but larger, longer-term studies are still needed to understand how much difference collagen-infused skincare can realistically make.
Do collagen masks have any side effects?
Topical collagen itself is unlikely to be a skin irritant, says Dr Allawh. Most collagen masks, however, contain extra active ingredients to boost anti-ageing results. These can include antioxidants such as vitamin C or botanical extracts, and those additions may trigger side effects in some skin types. Even though they are “natural,” they can still be irritating, Dr Allawh notes. Added fragrance is another common culprit for redness and stinging.
If a collagen mask causes immediate tingling, burning or visible redness, it is best to remove it straight away. A light cooling sensation followed by very mild tingling is more typical.
Always follow the instructions on the packaging and remove the mask at the recommended time. For best results, Dr Allawh suggests cleansing first with a gentle, fragrance-free face wash, applying the collagen mask as directed, then sealing everything in with a thin layer of moisturiser.
Do other products effectively boost skin’s collagen?
The best-studied topical ingredient for stimulating collagen production is a retinoid (or the milder over-the-counter form, retinol), a vitamin A derivative, says Dr Allawh. Retinoids have been shown to counteract wrinkles, sagging, discolouration and rough texture in clinical studies. Because retinoids can be irritating, some people use bakuchiol, a plant-derived alternative that research suggests can offer similar benefits with less sensitivity.
Dr Allawh also recommends using a vitamin C serum. Vitamin C helps defend against environmental damage that accelerates skin ageing, can help lighten areas of discolouration and supports collagen synthesis.
For more targeted results, a dermatologist may suggest in-clinic treatments such as lasers or radiofrequency devices. Many of these options have minimal downtime and work by heating the deeper layers of the skin to stimulate new collagen and elastin.
Finally, protecting the collagen already present in the skin is essential. Daily use of a broad-spectrum SPF facial sunscreen or moisturiser is one of the most effective ways to slow collagen breakdown and support smoother, firmer-looking skin over time.
