Hydroxyproline
Hydroxyproline is a naturally occurring amino acid that helps support the skin’s collagen structure, giving it a firmer, smoother and more youthful appearance. Commonly used in anti-ageing creams and serums, it is a favourite ingredient for those looking to improve skin elasticity and hydration.
How it works in skincare
In skincare formulations hydroxyproline works by supporting the skin’s natural collagen network, helping to improve firmness and elasticity while enhancing moisture retention. It is readily absorbed and integrates well into both water-based and oil-based cosmetic products, making it a versatile addition to daily moisturisers, eye creams and targeted anti-ageing treatments popular with British consumers.
