A night serum that clears breakouts and smooths skin texture
La Roche-Posay Effaclar Ultra Concentrated Serum is an exfoliating serum for oily, acne-prone adult skin. It combines glycolic acid, salicylic acid and LHA to remove dead cells, unclog pores and refine texture, with 2% niacinamide to calm the skin. Blemishes, blackheads and marks look reduced over time, and fine lines look softer.
The texture
A clear, watery serum that absorbs in seconds with no sticky feel. A few drops cover the face.
Who it suits
- Adults with persistent spots and blackheads
- Oily skin with enlarged pores
- Uneven texture and post-breakout marks
Worth knowing before you buy: the formula contains alcohol and fragrance, and its acids can sting dry or reactive skin. Start every other evening and use a sunscreen during the day.
