Does Collagen Work?

Does Supplementing with Collagen Improve Skin?

While there are a lot of naysayers on the internet denying that collagen helps improve skin, we dig into what the scientific journals have published on collagen to put this question to bed, once and for all!

Studies show that Collagen supplementation is effective in enhancing skin health, particularly in reducing signs of aging such as wrinkles and loss of elasticity. While most findings are positive, results can vary based on collagen source, dosage, and individual skin conditions.

Study 1: Nutrients (2019)

  • Experiment: A randomized, placebo-controlled trial involving 72 women aged 35 and older. Participants took a daily collagen peptide supplement or a placebo for 12 weeks.
  • Results: The study showed significant improvements in skin elasticity and hydration in the collagen group compared to the placebo group. Wrinkle depth was also reduced.
  • Conclusion: Collagen supplementation can enhance skin elasticity and reduce signs of aging.

Study 2: Skin Pharmacology and Physiology (2014)

  • Experiment: Double-blind, placebo-controlled study with 114 women aged 45-65. Participants received 2.5 g or 5 g of collagen peptides daily for 8 weeks.
  • Results: After 8 weeks, the collagen groups showed increased skin hydration and elasticity compared to the placebo. The higher dose group experienced more pronounced effects.
  • Conclusion: Oral collagen peptides significantly improve skin hydration and elasticity.

Study 3: Journal of Drugs in Dermatology (2019)

  • Experiment: A systematic review and meta-analysis of 11 studies with a total of 805 participants examining the effects of collagen supplementation on skin health.
  • Results: The analysis found that collagen supplementation led to improvements in skin hydration, elasticity, and dermal collagen density.
  • Conclusion: Collagen peptides effectively enhance skin appearance and may counteract aging-related changes.

These studies provide strong evidence that collagen supplements can improve skin health, particularly in terms of hydration, elasticity, and wrinkle reduction.

 

Additional Findings for Futher Reading

  1. Collagen supplementation is linked to improved skin hydration, elasticity, roughness, and density. Studies indicate benefits in reducing wrinkles and enhancing skin texture (Bolke et al., 2019).
  2. Collagen peptides support skin health by promoting collagen synthesis and reducing degradation. They enhance skin elasticity and hydration by influencing the extracellular matrix (Zhao et al., 2021).
  3. Numerous randomized controlled trials (RCTs) confirm collagen's role in improving skin health, showing significant results in reducing signs of aging (Asserin et al., 2015).
  4. Systematic reviews and meta-analyses conclude that oral collagen supplementation is effective for skin anti-aging, supporting both short-term and long-term benefits (de Miranda et al., 2021).
  5. Studies also explore collagen from different sources, including marine and animal-derived, showing varied but consistent positive outcomes (Evans et al., 2021).
