COSRX AHA 2% BHA 2% Blemish Treatment Serum with 60 Pre‑Soaked Cotton Balls — Targeted Spot Treatment & Sebum Control

COSRX AHA 2% BHA 2% Blemish Treatment Serum with pre-soaked pure cotton balls is a targeted spot treatment that helps clarify clogged pores and soothe post-acne discoloration.

This kit combines a gentle, low-dose chemical exfoliant serum (AHA 2% + BHA 2%) with 60 individually usable pure cotton balls to let you treat blemishes precisely, reduce whiteheads and blackheads, and limit unnecessary contact with surrounding healthy skin. Formulated to be free of parabens, phthalates and sulfates, the system aims to deliver exfoliation and sebum control while minimizing irritation and contamination from frequent product handling.

How does the AHA 2% + BHA 2% formula work on blocked pores?

The AHA component lifts and dissolves surface dead skin cells, while the BHA penetrates into oily pores to loosen sebum and debris. Together they encourage clearer pores without aggressive mechanical scrubbing, which helps reduce the formation of blackheads and whiteheads over time.

• AHA 2% gently exfoliates the skin surface to improve texture.
• BHA 2% (salicylic acid) works inside pores to dissolve sebum and debris.
• Low concentrations suitable for daily targeted use, not full-face over-exfoliation.
• Pre-soaked cotton balls allow precise application to individual blemishes.

Can I use these cotton balls for sensitive or acne-prone skin?

The cotton balls are 100% pure cotton and designed to limit product wastage and contact with unaffected skin, lowering the chance of irritation. The formula is kept at modest AHA/BHA percentages and the product is free of common irritants, but you should always patch-test first and avoid combining with other strong actives.

• Hypoallergenic, dermatologist-tested formulation.
• Paraben-, phthalate- and sulfate-free to reduce sensitizing ingredients.
• Apply to spots one at a time to avoid over-treating surrounding skin.
• Discontinue if excessive redness or stinging occurs; consult a professional if needed.

How do I use the pre-soaked cotton balls for best results?

Use the cotton balls as a quick, hygienic way to deliver the serum directly onto blemishes: cleanse, dry the area, then press a single cotton ball onto the spot until absorbed. Repeat once daily or as tolerated; avoid layering multiple strong exfoliants at the same time.

• Cleanse and pat the skin dry before application.
• Apply one cotton ball per blemish to avoid cross-contamination.
• Allow product to absorb; follow with moisturizer and sunscreen during daytime use.
• Do not rub vigorously—press and hold for even absorption.

What results should I expect and how quickly?

Results vary by skin type and severity, but you may notice reduced congestion and smoother texture within a few weeks of consistent, targeted use. The goal is to speed recovery of blemishes and lower the appearance of blackheads and whiteheads without unnecessary irritation.

• Initial reduction in surface flakiness and shine within days.
• Improvement in clogged pores and fewer new whiteheads/blackheads over weeks.
• Fewer product touches and lower contamination risk thanks to single-use cotton balls.
• Complement with sunscreen to protect renewed skin after exfoliation.

Who is this for: Suitable for anyone wanting a convenient, low-concentration chemical exfoliant for spot treatment—particularly people with oily or combination skin prone to blackheads and whiteheads who prefer hygienic, single-use application. Not recommended for very dry, severely irritated skin or for users already on multiple strong exfoliants; patch-test if you have sensitivity concerns.
