Collagen supplements come with many claims including: reduced signs of aging, such as firmer skin and fewer fine lines and wrinkles; improved skin hydration, resulting in smoother, softer skin; and stronger hair with reduced thinning and hair loss.
Despite the many claims propagated on social media, Dunnick emphasizes that there is very little data supporting the benefits of oral collagen supplementation.
The takeaway:
Collagen supplements are widely marketed for improving skin hydration, elasticity, and signs of aging, but current research shows only modest short-term benefits. According to Cory A. Dunnick, MD, professor of dermatology at the University of Colorado Anschutz School of Medicine, evidence supporting long-term improvements remains limited. For skin health and healthy aging, proven strategies such as sunscreen use, exercise and avoiding smoking remain more effective than collagen supplementation.
