A better life for sensitive skin.


Is there a term from the field of dermatology and cosmetics that you do not understand? Would you like to know what it means? View the full definition from the La Roche-Posay glossary.

Free radicals

Cells produce excess free radicals as a result of a variety of stresses. They are unstable oxygen molecules that use electrons and other molecules to self-stabilise. A chain reaction is then caused, leading to skin ageing.

This word belongs to the category Signs of age, wrinkles, firmness.
