This comprehensive review, published in the *Aesthetic Surgery Journal Open Forum*, provides strong evidence supporting the benefits of oral collagen supplementation for both skin health and joint wellness.
The study highlights that collagen, a key structural protein in the body, naturally diminishes with age and can be further degraded by environmental factors like UV exposure, pollution, and poor diet. When ingested, collagen is broken down into peptides that act as signals to stimulate tissue regeneration, encouraging the production of new collagen and improving skin firmness and hydration. Unlike topical collagen, which may only function as a moisturizing agent due to its large molecule size, oral collagen—especially hydrolyzed forms—is more effective in delivering these benefits.
While dermatologists are cautiously optimistic about the findings, they caution that many claims about collagen supplements are overstated. The study emphasizes the importance of choosing high-quality, well-researched products and using them consistently for optimal results.
