What it is + why it's regulated

Tretinoin, also known as retinoic acid and its salts, is a form of vitamin A used in some prescription skin treatments for conditions like acne and aging. In cosmetics, it is banned in the European Union under Regulation (EC) No 1223/2009, Annex II. This means it cannot be added to any cosmetic product sold in the EU, such as creams, lotions, or serums. The ban exists because tretinoin is a potent substance that can cause skin irritation, sun sensitivity, and other side effects when used without medical supervision. It is also classified by some health authorities as a possible developmental toxicant, meaning it could harm a developing fetus if absorbed in high amounts. The EU Cosmetics Regulation prioritizes consumer safety by restricting ingredients that pose risks in everyday products.
