Actives in formulation

摘要

Looking around this year's in-cosmeticsshow, one could be forgiven for thinking that cosmetics were composed entirely of natural ingredients, as each stand exhibited its latest extracts and actives from botanical sources.Active materials are predominantly aimed at anti-ageing products in an attempt to minimise the visible effects of ageing on skin. This may be achieved by providing an immediate tightening effect: a longer term rebuilding of the extracellular matrix leading to firmer skin, by providing antioxidants to combat free radical damage and by soothing, moisturising and adding beneficial oils to improve its barrier properties.
