New Umbrella Review Finds Collagen Supplements Help Skin Elasticity and Osteoarthritis — But Not Wrinkles or Workout Recovery
A 2026 umbrella review led by Anglia Ruskin University analyzed nearly 8,000 participants across 16 systematic reviews and 113 trials, finding collagen supplements improve skin elasticity, hydration and ease osteoarthritis symptoms but not wrinkles or workout recovery.
Key takeaways
- Evidence supports modest improvements in skin elasticity and skin hydration with regular hydrolyzed collagen use.
- Clear benefit for reducing osteoarthritis pain and stiffness, suggesting a potential adjunct to standard care.
- No meaningful effect on skin roughness/wrinkles, post-exercise muscle recovery, soreness, or tendon mechanical properties.
- Quality varies: higher-quality, independent trials often show smaller or no effects; more rigorous long-term studies are needed.

What was done
Researchers at Anglia Ruskin University pooled 16 systematic reviews and 113 randomized controlled trials covering nearly 8,000 people to evaluate collagen supplements. The results were published in Aesthetic Surgery Journal Open Forum. See coverage in Women’s Health and Professional Beauty.
Why researchers took a broad look
Collagen is the body’s most abundant protein and supports skin, bones, tendons, cartilage and other connective tissues. Natural collagen production declines with age, and supplement sales have surged with broad marketing claims. To separate marketing from evidence, the team conducted an umbrella review — a study of studies — and intentionally included trials without known industry funding. Reporting and expert reactions appear in Women’s Health and Professional Beauty.
What the review found: skin benefits
The most consistent signals were for skin elasticity and hydration. Several trials of oral, hydrolyzed collagen — peptides broken into absorbable fragments — showed gradual improvements in skin firmness and moisture over weeks to months. Researchers noted peptides can appear in blood within an hour and may help signal the body to support its own collagen production.
Co-author Jose Francisco Lopez-Gil described collagen as “foundational dermal support” rather than a quick wrinkle remedy.
Skin roughness and wrinkles
Despite gains in elasticity and hydration, the pooled trials did not show meaningful change in skin roughness, a proxy for visible wrinkle depth and surface texture. In short: don’t expect collagen tablets or powders to erase fine lines quickly. Benefits tend to accumulate slowly and may be subtle. Trials often varied in controlling UV exposure, smoking, sleep, hormones and other product use, complicating direct attribution.
Joint and musculoskeletal effects
The review reported clear evidence that collagen supplementation can reduce osteoarthritis pain and stiffness. Some randomized trials showed symptom improvement for people with osteoarthritis, suggesting collagen may be a useful adjunct to standard care. However, evidence for improvements in muscle mass, tendon structure or athletic performance was mixed or absent.
Specifically, the review did not find meaningful benefits for post-exercise muscle recovery, soreness, or tendon mechanical properties such as strength and elasticity. Athletes should be cautious about using collagen specifically to speed workout recovery.
Quality, funding and study limitations
Authors noted earlier positive findings were sometimes tied to lower-quality or industry-funded studies. Higher-quality, independent trials tended to show smaller or no effects. Experts recommended more rigorous, long-term trials that better control lifestyle factors. For context, a 2023 analysis from Harvard Health Blog found mixed results and suggested added ingredients (like vitamin C) may explain some benefits attributed to collagen alone.
Practical takeaways for consumers
- For skin elasticity & hydration: modest improvements are possible over months with consistent hydrolyzed collagen use.
- For wrinkles: collagen did not significantly reduce skin roughness; manage expectations and prioritize sun protection and healthy habits.
- For osteoarthritis: collagen may ease pain and stiffness as part of a broader treatment plan — consult your doctor first.
- For workout recovery: current evidence does not support collagen as an effective recovery aid; use proven recovery strategies instead.
Implications for San Diego
San Diego consumers and businesses should align marketing and advice with the evidence: local retailers, wellness clinics and spas can emphasize modest skin elasticity and hydration benefits and potential osteoarthritis relief, while avoiding claims about rapid wrinkle removal or faster athletic recovery. Health providers and community programs should highlight cost-effective alternatives — sunscreen, balanced diets (adequate protein and vitamin C), smoking cessation and medical care — especially for lower-income residents.
San Diego research hospitals and universities might also contribute higher-quality local trials, for example studying interactions between collagen use and high sun exposure typical of the region.
