La Roche-Posay Effaclar Dual Acne Face Wash — 4% Benzoyl Peroxide Gel with LHA, Fragrance-Free 6.76 fl oz

La Roche-Posay Effaclar Dual is a dual-action facial cleanser that combines 4% benzoyl peroxide with micro-exfoliating LHA to cleanse oily, acne-prone skin while helping reduce blemishes and smooth skin texture.

This targeted acne wash pairs a proven acne-fighting ingredient with a gentle chemical exfoliant to address excess oil, surface dead skin, and breakouts in one step. Formulated to be fragrance-free, non-comedogenic, and suitable for sensitive skin testing, the gel cleanser aims to remove impurities and promote a more even-looking complexion without heavy oils or parabens.

How does this cleanser treat existing blemishes?

The 4% benzoyl peroxide component works to reduce acne-causing bacteria on the skin's surface, helping to clear active blemishes over regular use. Because benzoyl peroxide can oxidize oils and address plugged pores, it contributes to faster resolution of pimples when used as directed.

• 4% benzoyl peroxide to target acne-causing bacteria
• Gel formula rinses thoroughly to remove debris from pores
• Suitable for routine morning or evening cleansing

What role does LHA play in improving skin texture?

Micro-exfoliating LHA (lipohydroxy acid) gently loosens dead skin cells and smooths rough patches without harsh scrubbing. Its targeted exfoliation helps prevent pore clogging and encourages a more refined surface, which supports clearer-looking skin over time.

• 0.1% LHA provides controlled chemical exfoliation
• Refines skin surface to reduce the appearance of uneven texture
• Less abrasive than physical scrubs, suitable for sensitive areas

Will this face wash dry out or irritate sensitive skin?

The formulation is fragrance-free, oil-free, and non-comedogenic, designed to balance acne effectiveness with gentler support for reactive skin types. Users prone to dryness or sensitivity should introduce the product gradually and follow with a dermatologist-approved moisturizer to maintain hydration.

• Fragrance-free and paraben-free for reduced irritation risk
• Oil-free gel texture that rinses clean without residue
• Tested on sensitive skin; patch testing recommended for new users

How should I fit this wash into my acne care routine?

Use the cleanser as your primary face wash once or twice daily, depending on tolerance and dermatologist guidance. After cleansing, apply any prescribed topical treatments and a moisturizer, finishing with SPF in daytime routines to protect treated skin.

• Apply to damp skin, lather gently, then rinse thoroughly
• Follow with moisturizer and daily sun protection for daytime use
• Avoid combining with other strong exfoliants unless advised by a clinician

Who is this for: Effaclar Dual 4% Benzoyl Peroxide Face Wash is intended for people with oily or acne-prone skin who want a single-step cleanser that addresses both active blemishes and surface texture.
