Collagen supplements help slow down the ageing process, especially skin and hair

Collagen supplements show promising evidence for slowing skin aging, but research is still developing, and there is minimal evidence regarding hair specifically.

Skin Aging

Multiple studies indicate that oral collagen supplements can reduce wrinkles and improve skin health. A systematic review of randomized controlled trials found that both oral and topical collagen supplements help delay the aging process, with improvements in skin moisture, elasticity, and hydration[1]. One analysis of 26 studies found that taking 1–12 grams of collagen daily for 4–12 weeks led to improvements in skin elasticity and hydration[2]. Clinical research has demonstrated more substantial results; for example, one study showed approximately three-quarters of treated women experienced anti-wrinkling effects and increased dermal density and elasticity after 7 days of treatment, with patients showing 60–80% skin improvement from baseline[1].

The mechanism appears to involve collagen providing essential components for maintaining skin structure while also triggering fibroblasts to produce elastin and hyaluronic acid[1].

Limitations and Caution

However, important caveats exist. A Tufts dermatologist emphasizes that oral collagen supplements may not be as effective for skin aging as commonly believed[6]. Another expert source notes that while research on collagen supplements for anti-aging shows "promising signs," evidence remains "not yet conclusive"[3]. Additionally, the Cleveland Clinic indicates that scientific research is lacking for most collagen claims[7].

Hair

The search results provided contain no specific evidence addressing collagen's effects on hair aging, representing a significant gap in the available information.
