Ko'zen
For a soothed skin

Sensitive, fragile and irritated skin types are characterized by cutaneous hypersensitivity. This results in sensations of discomfort,stinging and tightness, particularly in the face. These skin types rapidly develop excessive reactions to external stress factors (pollution, wind, temperature variations, frequent use of cleansing products, etc.),causing inflammation and even irritation.

Ko'zen is a plant-origin active ingredient obtained from quince leaves, rich in polyphenols. It protects the skin from daily stress factors and excessive inflammatory reactions, for a skin soothed and comfortable.
