About the Product

This multi-acid peel combines four types of exfoliating acids—AHA, BHA, PHA, and LHA—to tackle texture, congestion, and dullness in one weekly treatment. AHAs and BHAs work at different depths to resurface skin and clear pores, while PHAs and LHAs offer gentler exfoliation with less irritation potential. It's a stronger formula, so it's best suited for those already comfortable with acid exfoliation.

Who is This For?

Ideal for anyone with experience using chemical exfoliants who wants a more intensive treatment. Especially helpful for oily or combination skin dealing with texture, clogged pores, or dullness, but works well for resilient skin types looking to level up their exfoliation routine.

Key Benefits

  • Targets multiple concerns at once—texture, congestion, blackheads, and dullness
  • Clears out pore buildup while smoothing the skin's surface
  • PHA adds gentle exfoliation with hydrating properties
  • Designed as a weekly treatment so you get results without overdoing it

Key Ingredients

  • AHA (Alpha Hydroxy Acid) — Exfoliates the skin's surface to improve texture and encourage cell turnover
  • BHA (Beta Hydroxy Acid) — Goes deeper into pores to dissolve oil and clear congestion
  • PHA (Polyhydroxy Acid) — A gentler exfoliating acid that also helps skin retain moisture
  • LHA (Lipohydroxy Acid) — A slow-release derivative of salicylic acid that exfoliates gradually with less irritation
FAQs

Q: Can beginners use the COSRX AHA BHA PHA LHA 35 Peel?
A: This peel is formulated for experienced users familiar with acid exfoliation; beginners should start with lower-concentration acid products before progressing to this treatment.

Q: How often should I use this peel?
A: Use once per week maximum in your PM routine; more frequent use may cause irritation or compromise the skin barrier.

Q: Can I use retinol on the same night as this peel?
A: Do not use retinol or other active ingredients on the same evening; wait at least 24–48 hours before applying retinoids or other potent actives.

Q: Is this peel suitable for sensitive skin?
A: This product contains a high concentration of multiple acids and is not recommended for sensitive or reactive skin types.

Q: When will I see results?
A: Most users notice smoother texture and clearer pores within 2–4 weeks of consistent weekly use.

Q: Who should avoid this product?
A: Those with sensitive, reactive, or compromised skin barriers should skip this peel, as well as anyone currently using prescription retinoids or other strong actives without consulting a dermatologist.

Q: Do I need to wear sunscreen after using this peel?
A: Yes, acids increase sun sensitivity, so apply SPF 30 or higher every morning—especially important in the days following use.

How to Use

Cleanse face thoroughly and pat skin completely dry. Conduct a patch test on a small area before first use. Apply a generous, even layer to the face, avoiding the eye area and lips.
