Three meta-analyses compared

ReviewSizeFinding
de Miranda 2021, Int J Dermatol19 RCTs, 1,125 participants (95% women, ages 20–70)Improved hydration, elasticity and wrinkles at ~90 days
Pu 2023, Nutrients26 RCTs, 1,721 peopleImproved hydration and elasticity
Am J Med 202523 RCTs, 1,474 peoplePositive overall — but studies not funded by companies, and high-quality studies, showed no significant effect

Why the results disagree

The newest review split the studies by who paid for them. Industry-funded studies drove the positive results; the independent and high-quality studies found no significant effect.

Collagen masks and creams

Topical collagen — like the BIODANCE overnight mask (#S04) or medicube's collagen cream (#S03) — works as a moisturizer: it hydrates and forms a film that slows water loss. It isn't shown to build collagen in your skin. Enjoy it for that.

Stronger-evidence basics

Daily sunscreen (#S09) and a retinoid (#S19) have stronger evidence for skin aging than collagen. See choosing a sunscreen and menopause skin care.
