Wound healing and skin ageing – the growing evidence for collagen supplementation

Collagen supplements are widely marketed for improving skin health and integrity, while reducing the visible signs of ageing. However, until recently peer-reviewed literature has been lacking to substantiate the clinical benefits and potential applications of collagen.

To understand the uses, efficacy and doses of collagen, two recent systematic reviews analysed the available research. They found that collagen supplements have benefits in wound healing, potential uses in medically diagnosed skin conditions and skin anti-ageing effects.
