La Roche-Posay Effaclar Salicylic Acid Serum, 30 ml - LHA + Glycolic Acid for Pore Refining & Acne‑Prone Skin

La Roche-Posay Effaclar Salicylic Acid Serum is a lightweight exfoliating treatment designed to clear acne blemishes, refine enlarged pores and improve skin texture without heavy residue.

This concentrated serum combines a salicylic acid derivative (LHA) with glycolic acid and hyaluronic acid to gently renew the skin surface, reduce the appearance of pores and support a clearer, more even complexion. Fragrance-free, non-comedogenic and formulated for oily, blemish-prone skin, it’s intended for controlled, progressive use to minimize irritation and maximize visible smoothing.

How quickly will I notice fewer blemishes and clearer skin?

Visible improvements often appear after a few weeks of consistent use, though timelines vary by skin type and severity of breakouts. Begin gradually to allow skin to adapt and reduce the chance of sensitivity; benefits accumulate with nightly application as directed.

• Start using every other night during week one, then nightly as tolerated.
• Use 2–3 drops to cover the whole face—small amounts are effective.
• Combine with SPF during daytime—AHA ingredients can increase sun sensitivity.

What ingredients make this serum effective for oily and textured skin?

The formula pairs LHA (a salicylic acid derivative) for targeted micro‑exfoliation with glycolic acid to accelerate surface renewal, while hydrolyzed hyaluronic acid helps maintain hydration. Alcohol denat. speeds absorption and leaves a non-greasy finish; the product is free of parabens and added fragrance.

• Capryloyl salicylic acid (LHA): exfoliates and refines pore appearance.
• Glycolic acid: promotes cell turnover and smoother texture.
• Hydrolyzed hyaluronic acid: supports moisture without clogging pores.

How do I fit this serum into my morning and evening routine?

Use the serum in the evening after cleansing and before heavier treatments; in the morning, pair it with a broad‑spectrum sunscreen (SPF 15 or higher) to protect renewed skin. If layering with other actives, introduce gradually and watch for signs of irritation.

• Evening: apply 2–3 drops to clean, dry skin—avoid the eye contour.
• Morning: wear sunscreen every day while using this product and for one week after stopping.
• Introduce alongside retinoids or other acids slowly to minimize over‑exfoliation.

Is this serum suitable for sensitive or acne-prone skin?

The formulation was developed for oily, blemish‑prone complexions and is non-comedogenic and fragrance-free, but it contains AHAs/BHAs that can increase irritation for very sensitive skin. A patch test and gradual introduction are recommended; discontinue if persistent redness or discomfort occurs.

• Not recommended for very sensitive skin without prior dermatologist advice.
• Patch test behind the ear or on the inner forearm before full-face use.
• If sensitivity appears, reduce frequency or consult a dermatologist.

Who is this for: La Roche-Posay Effaclar Salicylic Acid Serum targets people with oily, textured or blemish-prone skin who want a lightweight, dermatologist-developed exfoliating treatment to refine pores and even skin tone. It’s suited to users willing to introduce active acids progressively and to follow sun protection guidance while the skin renews.
