COSRX BHA Blackhead Power Liquid — Honest Review

Lightweight BHA exfoliant for blackheads, clogged pores, and texture—what it does, who it suits, and whether it’s worth buying.

Short verdict: A gentle, effective BHA exfoliant that’s excellent for oily and combination skin. Not an overnight miracle, but consistent use reduces blackheads and smooths texture.

What it is

This COSRX formula is a leave-on chemical exfoliant that uses BHA to penetrate and dissolve pore buildup. It’s popular for clearing blackheads while remaining gentle on the skin.

How to use

  1. Cleanse and pat skin dry.
  2. Apply a thin layer (use 2-3 drops or a single pump, depending on packaging) after toner.
  3. Start 2x/week and build to nightly if tolerated.
  4. Follow with moisturizer and always apply SPF in daytime.

Who should try it

Works best for: oily, combination, and congested skin types. If you have very sensitive skin, patch-test first or consult a dermatologist.

Pros & Cons

✔ Pros: reduces blackheads, lightweight, good value, beginner-friendly strength.
✖ Cons: possible initial purge, slower visible change (3–6 weeks), not ideal for severe sensitivity.

Tips for best results

  • Introduce slowly — twice weekly for 2 weeks, then increase as tolerated.
  • Always finish with a hydrating moisturizer to keep barrier healthy.
  • If you experience irritation, reduce frequency or pause until skin calms.

My overall rating

4.2 / 5 — Gentle, effective, strong value
Expected visible improvement: 3–6 weeks

Recommended if your main concern is clogged pores and blackheads and you prefer a leave-on chemical exfoliant over physical scrubs.

Final thought

For many people, COSRX BHA Blackhead Power Liquid is a reliable step-up from basic cleansers or scrubs. It’s gentle, plays well under other skincare steps, and gives visible pore improvements when used consistently.
