La Roche Posay Effaclar Ultra Concentrated Serum 30ml

Discover clearer, smoother and more refined-looking skin with La Roche-Posay Effaclar Ultra Concentrated Serum, an advanced daily peeling serum specially formulated for adults with acne-prone skin.

Designed to target persistent imperfections, post-acne marks and visible pores, this lightweight exfoliating serum combines three powerful exfoliating acids — Salicylic Acid, Glycolic Acid and LHA — with soothing Niacinamide.

The concentrated tri-acid complex helps unclog pores, remove dead skin cells and support natural skin renewal. Niacinamide helps soothe the skin and support its protective barrier, balancing the exfoliating action of the formula.

Its fast-absorbing, non-sticky texture leaves skin feeling smoother, fresher and more refined without a heavy finish.

Suitable for adult acne-prone skin, this serum is designed to address recurring blemishes, blackheads, uneven skin texture and visible post-acne marks.
