COSRX 35% AHA BHA PHA LHA Peel — 30 ml concentrated weekly chemical exfoliant for smoother, brighter skin

This concentrated peeling gel combines multiple acids in a single formula to accelerate surface exfoliation and pore clearing while supporting barrier resilience. Designed as a weekly treatment, the product aims to reveal smoother, brighter skin by loosening dead cells and helping remove built-up sebum and debris. Because of its potency, it should be used with care—patch testing and following the recommended exposure time are essential steps.

How quickly will I see texture and brightness improvements?

Visible smoothing and a brighter appearance can be noticed after a single use for many people because the gel mechanically and chemically removes surface dead skin. Results vary by skin condition and previous exfoliation routine; those with heavier buildup may need several weekly sessions to reach their desired outcome.

• Single-use: immediate removal of flaking, revealing fresher surface.
• 1–4 weekly uses: progressive refinement of texture and tone.
• Complement with sunscreen daily to protect newly revealed skin.

Is this safe for sensitive or acne-prone skin?

The formula pairs AHA, BHA, PHA and a small amount of LHA to target different layers and concerns while PHA supports barrier protection. However, the overall 35% concentration is potent; sensitive or inflamed skin types should proceed cautiously and consider a patch test or consulting a skincare professional before facial use.

• Patch test recommended 24 hours prior to facial application.
• Limit to once weekly to minimize irritation risk.
• Avoid use on broken, sunburned, or actively irritated skin.

How do I use the peel safely and effectively?

Apply to clean, dry skin, steering clear of the eye area and lips, then leave on for up to 10 minutes before rinsing thoroughly with lukewarm water. Use only once per week and follow with gentle, hydrating products and daily SPF to protect the refreshed skin surface.

• Use on clean, dry face; avoid mucous membranes and open wounds.
• Limit contact time to a maximum of 10 minutes as directed.
• Rinse well and follow with soothing, non-irritating moisturizers.

What are the active acids and what do they do?

This peel blends multiple acid types so each addresses a different concern: AHA works on surface dead cells, BHA penetrates pores to help clear sebum, PHA offers a gentler exfoliation and supports barrier integrity, and LHA contributes targeted resurfacing. The synergy aims to refine pores, smooth fine texture and improve the look of uneven tone without relying on mechanical scrubbing.

• AHA (majority): loosens and removes outer dead skin cells.
• BHA: oil-soluble, helps clear clogged pores and excess sebum.
• PHA: hydrates while providing milder exfoliation and barrier support.
• LHA: low concentration for targeted resurfacing and tone improvement.

Who is this for? COSRX 35% AHA BHA PHA LHA Peel is intended for experienced exfoliant users with dull, rough, oily, or congested skin who want a concentrated weekly treatment to accelerate cell turnover and pore clearing. If you are new to chemical peels, have very sensitive or compromised skin, or are unsure about interactions with other active treatments, start with a professional consultation or gentler alternatives first. Always follow patch testing instructions and protect treated skin with daily sunscreen.
