COSRX AHA BHA PHA LHA 35% Peel Exfoliating Gel 30ml — Weekly Wash-Off Multi-Acid for Dull, Congested Skin

COSRX AHA BHA PHA LHA 35% Peel is a potent wash-off chemical exfoliant that dissolves dead skin, clears clogged pores and refines texture in a single weekly treatment.

This concentrated peeling gel blends multiple acids and a vitamin complex to accelerate surface renewal without physical scrubbing. Designed as a short-contact treatment, it targets dullness, uneven texture and pore congestion. Because the formula is strong, it’s intended for occasional use and requires a prior patch test to ensure skin tolerance.

How does this multi-acid peel work on rough, congested skin?

The peel combines exfoliating molecules that act at different skin layers: AHAs loosen bonds between dead cells on the surface, BHA penetrates and helps dislodge sebum inside pores, PHA supports barrier resilience, and LHA targets discoloration and texture. Used as a brief rinse-off treatment, it accelerates cell turnover for smoother, clearer-looking skin without manual abrasion.

• Contains 35% total acids with targeted percentages for layered action.
• Wash-off format reduces prolonged acid exposure compared with leave-on products.
• Improves surface brightness and helps reduce visible pore congestion.

Is this safe for sensitive or reactive skin types?

Because of its high acid concentration, the product can be irritating for sensitive or compromised skin. COSRX formulates the peel with PHA and a vitamin trio to help cushion irritation, but a patch test and conservative application are essential. If redness or burning occurs, discontinue and rinse thoroughly.

• Patch test on the body 24 hours before facial use.
• Apply only to clean, dry skin and avoid eyes and lips.
• Limit to one short application per week to reduce irritation risk.

What’s the proper way to use this peel for best results and safety?

Dispense a generous layer onto dry, cleansed skin, keeping clear of the eye area and lips. Leave the product on for up to ten minutes, then rinse thoroughly with lukewarm water; do not exceed the recommended contact time. Follow with sun protection the next day, since exfoliation increases sun sensitivity.

• Use once weekly as a short-contact wash-off treatment.
• Rinse fully after a maximum of 10 minutes to stop acid activity.
• Apply sunscreen the following day to protect newly revealed skin.

Which skin concerns will users likely notice improving first?

Visible changes typically include a brighter surface, softer texture and reduced appearance of clogged pores after a few treatments. Because it speeds exfoliation, users often see quick smoothing effects; deeper concerns like scarring or advanced hyperpigmentation require consistent, long-term skincare beyond a single peel.

• First improvements: surface glow and smoother texture.
• Medium-term: clearer pores and more even tone with repeated use.
• Not a substitute for prescription care for severe concerns.

Who is this for? The COSRX 35% Multi-Acid Peel suits people with oily, combination or dull textured skin who want a powerful, once-weekly chemical exfoliant. Avoid if you have very sensitive, eczema-prone or broken skin, and always consult a dermatologist before combining with other strong actives. When used properly—patch tested, applied briefly and followed by sun protection—it’s a fast-acting option to refresh and refine the skin’s surface.
