What it is
Collagen is a protein that keeps skin firm, elastic and youthful. As we age, natural collagen production declines, leading to sagging and wrinkles. Collagen-boosting ingredients, such as retinoids, peptides and vitamin C, help maintain skin structure.
Some opt for collagen supplements, though evidence varies. Protecting existing collagen with SPF and antioxidants is key to preserving a youthful complexion.
Does Collagen in skincare Work
Topical collagen products are often marketed as a way to improve skin elasticity and hydration, but they don’t work the way users think because of the science of molecule size and skin absorption.
Collagen molecules are too large to penetrate the outermost layer of the skin, the stratum corneum. The stratum corneum is designed to act as a protective barrier, preventing large substances from entering the deeper layers of the skin. As a result, collagen applied topically cannot reach the dermis to effectively stimulate collagen production and provide structural benefits.
Instead, topical collagen products can provide a temporary smoothing or hydrating effect on the skin’s surface by forming a film, which helps retain moisture. While this may lend the skin a temporarily more plumped appearance, it does not address deeper skin concerns such as of elasticity and collagen degradation.
For meaningful results, I recommend ingredients such as retinoids, which stimulate collagen production, and procedures including microneedling and laser therapy that target the dermis directly and far more effectively.
