Study Shows Collagen Supplements May ‘Promote Skin Health’
Collagen supplements are not a “quick fix” for wrinkles, according to experts, but they offer “legitimate” benefits.
The new research from Anglia Ruskin University (ARU) analyses evidence from 16 reviews and 113 trials involving almost 8,000 patients worldwide.
The review found that long-term supplements can improve skin elasticity and hydration and reduce arthritis symptoms, such as joint stiffness and pain.
However, they did not have any significant effect on skin roughness.
It states that the products should be reserved for people seeking “holistic” skin maintenance.
and found that supplements represent a “legitimate” additional anti-ageing treatment for women.
Those who have undergone menopause or suffer from UV-damaged skin may benefit from these supplements.
“Collagen may be best positioned not as an anti-wrinkle ‘quick fix’ but as a foundational dermal support for individuals seeking overall skin maintenance,” the researchers said.
The supplements therefore support an “inside-out model of skin rejuvenation”, the study found, acting as “agents of deep tissue regeneration” rather than as a “superficial cosmetic aid”.
‘Bold Claims’
Professor of public health at ARU, Lee Smith, stated: “Those marketing the product often make bold claims regarding collagen supplementation.”
For instance, manufacturers have made ‘promises’ that collagen supplementation leads to significant, rapid, and comprehensive anti-ageing.
“Collagen is not a cure-all, but it has reliable benefits when used consistently over time, especially for skin and osteoarthritis.
“Our findings show clear benefits in key areas of healthy ageing while also dispelling some of the myths associated with its use.”
He added, “If we define anti-ageing as a product or technology designed to prevent ageing, I believe our findings support this claim for some parameters.
“For example, improvements in skin tone and moisture are associated with a more youthful appearance.”
cost implication
But according to Shefali Loth, a nutritionist at the consumer group Which?, consumers should be mindful of the cost.

Responding to the study, he said, “Collagen supplements are often marketed with anti-ageing claims, but the scientific evidence to support them is limited.
“It is worth remembering that there are currently no approved health claims for collagen supplements on the Nutrition and Health Claims Register.
“The cost of taking collagen can add up quickly. Most supplements cost at least £25 per month for daily use, and studies show that they need to be taken consistently for best results.
“Consumers should be cautious about brand claims and weigh the potential benefits versus costs before committing to long-term use.”
The study authors acknowledged that more analysis is needed on factors such as the dosage of collagen and how long it is taken, and whether body composition affects its effectiveness.
The review was published in the Aesthetic Surgery Journal Open Forum.
