It is difficult to say whether it is better to take collagen internally as part of a beauty product or in capsule form. The benefits of collagen supplements have not been extensively studied, so it is hard to recommend them for improving joint and cartilage health. As for cosmetic products claiming to contain collagen, they may not fully reverse the effects of aging on elasticity. Instead, choosing a good, non-pore-clogging moisturizer suited to your skin type can help maintain healthy and youthful-looking skin.
