Collagen for Skin Health
Collagen supplements are studied for skin hydration and elasticity, but evidence varies with study quality. A benefit or a fixed result cannot be promised for an individual product.
The Science Behind It
A 2025 review of 23 trials found benefits in pooled results, but not in the high-quality studies or studies without pharmaceutical-company funding. This does not establish that every collagen product improves skin.
