This lightweight salicylic acid acne treatment serum clears acne blemishes and helps prevent new breakouts, while also visibly reducing pores, fine lines, and post-acne marks.
This serum includes Triple Acid Complex, a blend of 1.5% salicylic acid, glycolic acid, and micro-exfoliating lipo-hydroxy acid for optimal efficacy. This formula also includes Niacinamide and La Roche-Posay Thermal Water to help soothe skin and minimize skin irritation.

KEY INGREDIENTS

How Does Effaclar Serum Target Acne?

Frequently Asked Questions

Effaclar Serum should be applied after cleansing and followed by a moisturizer in the morning and evening. If using during the daytime, apply daily sun protection*.

Here is a simple routine to integrate Effaclar Serum :

Step 1: Cleanse (AM/PM) – Begin by washing your face with a purifying cleanser, such as Effaclar Medicated Gel Facial Wash, to remove excess oil and impurities.
Step 2: Treat (AM/PM) – Apply Effaclar Serum evenly to clean, dry skin.
Step 3: Moisturize (AM/PM) – Follow with a lightweight, oil-free moisturizer like Toleriane Double Repair Moisturizer Matte to hydrate and protect the skin barrier.
Step 4: Protect (AM Only) – Finish your morning routine with a broad-spectrum daily sunscreen, such as Anthelios UV Control Sunscreen SPF 50.

Yes, Effaclar Serum can be combined with other skincare products, but it is important to pair it with a gentle moisturizer and always use sunscreen* during the day, as exfoliating acids can make the skin more sensitive to the sun. Avoid using other strong exfoliants in the same routine to prevent irritation.
