Which skincare ingredients are banned or restricted in the EU?

Over 700 substances are banned in EU cosmetics, including certain UV filters, preservatives (like BHA), colorants, and botanical extracts. Restricted ingredients include salicylic acid (max 2%), glycolic acid (max 10%), hydroquinone (banned), and formaldehyde (banned). Your reformulation must substitute these with EU-approved alternatives like niacinamide, azelaic acid, or EU-compliant preservative systems.
