La Roche-Posay Effaclar Ultra-Concentrated Serum 30 ml

When your skin suddenly starts to “act up” — breakouts, blackheads, and post-acne marks appear — you want a product that truly works, quickly and effectively. This is exactly how La Roche-Posay Effaclar Ultra-Concentrated Serum 30 ml is positioned. Behind its minimalistic bottle lies not just a serum, but a powerful concentrate of active ingredients that works almost like an at-home peel.

This high-potency peeling serum is specifically developed for adults with oily, acne-prone skin. It combines a triple-acid complex with niacinamide to target imperfections, post-acne marks, and enlarged pores.

Key Benefits

Visible reduction of imperfections:
Clinically proven to reduce pimples by up to 45%, blackheads by 21–50%, and post-acne marks by 49% after 4 weeks of use.

Anti-aging effect:
Helps smooth skin texture and reduce the appearance of fine lines.

Pore refinement:
Deeply cleanses pores from excess sebum and dead skin cells, making them less visible.

Texture:
Lightweight, non-sticky gel texture that absorbs quickly into the skin.

Key Ingredients

The formula features a three-acid complex:

• Salicylic Acid (1.5%) — unclogs pores and prevents excess sebum buildup


• Glycolic Acid (3.5%) — boosts cell renewal, improves radiance, and reduces post-acne marks


• LHA (0.45%) — a gentle exfoliating derivative for smoother skin texture


• Niacinamide (Vitamin B3) — soothes irritation and strengthens the skin barrier


• La Roche-Posay Thermal Spring Water — known for its soothing and antioxidant properties

How to Use

• When: Once daily, preferably in the evening


• How: Apply 2–3 drops to clean skin, avoiding the eye area


• Sun protection: Always use sunscreen (minimum SPF 15) in the morning during use


• Adaptation: For sensitive skin, start every other day and gradually increase frequency

Important to Know

This is not a gentle everyday moisturizer — it is an active treatment. A slight tingling sensation during the first applications is normal, as the acids begin working immediately. With consistent use, skin becomes smoother, pores less visible, and breakouts gradually decrease.
