Collagen May Improve Elasticity, But Won’t Prevent Wrinkles
A review of 113 trials with about 8,000 participants finds daily collagen can improve skin elasticity and hydration over time but does not prevent wrinkles; it may also ease joint pain, though it is not a cure-all. Benefits come with consistent use and vary by supplement type (marine, bovine, vegan) with no clear winner. Diets rich in vitamin C and zinc support collagen production, and more dermatology-focused studies are needed to confirm these effects.
