Collagen: Hype vs. Reality for Skin Health

A prominent skin expert has cautioned consumers about the widespread use of collagen supplements, suggesting they are not the 'miracle cure' often advertised. Despite their popularity in the UK, where 10% of adults have tried them, new research indicates mixed results.

A meta-analysis of numerous trials found some improvements in skin hydration, elasticity, and wrinkles. However, higher-quality studies, particularly those without pharmaceutical funding, showed no significant benefits, leading to conclusions of insufficient evidence for anti-aging effects.

Dr. Conal Perrett explains that the digestive system breaks down ingested collagen into amino acids and peptides. These are then used by the body for various functions, not exclusively for skin repair. He stresses that marketing claims should be viewed with caution.

Instead of relying solely on supplements, Dr. Perrett advocates for foundational health practices. These include a varied diet with ample protein and Vitamin C, alongside consistent sun protection, as being more critical for maintaining skin health and protecting existing collagen.
