Supplements for Skin

What the Research Shows

Research on skin supplements shows varying levels of effectiveness depending on the ingredient. Collagen supplements currently have moderate evidence suggesting they may improve skin elasticity and hydration, though results often vary by the type of collagen used. Other common additions, such as biotin or hyaluronic acid capsules, have weak or insufficient evidence to support claims that they significantly improve skin quality when taken orally rather than applied topically. Many popular skin supplements lack rigorous, large-scale human trials, making it difficult to determine definitive benefits. Evidence for antioxidants like Vitamin C and E is generally strong for overall health, but their specific impact on skin aging via supplementation remains conflicting. Because many studies are funded by supplement manufacturers, the current body of research is limited by potential bias and a lack of standardized dosing across trials.
