Cosrx BHA Blackhead Power Liquid
Reddit take
AI summary of the Reddit excerpts below — not a quote
The Cosrx BHA Blackhead Power Liquid is widely regarded as a gentle, entry-level chemical exfoliant effective for clearing clogged pores and improving skin texture. Unlike more aggressive BHA treatments, it uses betaine salicylate, making it a popular recommendation for those with sensitive skin or those new to acids. While generally well-received, users emphasize that it requires consistent use over several weeks to see results and can still cause significant dryness or peeling if over-applied.
Pros
- Gentle formula suitable for sensitive skin and beginners
- Effective at clearing forehead bumps and congested pores
- Contains niacinamide which helps with skin texture
- Less irritating than high-strength salicylic acid treatments
- Works well as a leave-on treatment compared to wash-off cleansers
Cons
- Can cause skin peeling and extreme dryness if used daily or too frequently
- May cause an initial 'purging' period or breakouts for some users
- Some users find it too weak for significant oil control compared to stronger BHAs
- Results are not immediate, often requiring 6-8 weeks of consistent use
Caveats
- Frequent reports of skin barrier damage when users ignored the 2-3x weekly recommendation and used it daily
- Users recommend alternating days with other actives like retinol to minimize irritation
- It is a 'gentle' BHA (betaine salicylate), which may not be powerful enough for very resilient or extremely oily skin types
Best for
- Sensitive skin types needing pore maintenance
- Beginners to chemical exfoliation
- Treating blackheads and minor skin texture issues
Avoid if
- You have very resilient skin and require a high-strength (2%+) salicylic acid for severe oiliness
- You are prone to over-exfoliating and cannot stick to a 2-3x weekly schedule

I think the only thing you might benefit from might be some gentle chemical exfoliation like Cosrx BHA blackhead power liquid (gentle BHA + niacinamide) or The Ordinary's 10% lactic acid serum w/ hyaluronic acid.
The Cosrx BHA Blackhead Power Liquid is a fantastic, gentle K-beauty option.
COSRX BHA Blackhead Power Liquid → 2×/week instead of Kiehl’s
Example: COSRX BHA Blackhead Power Liquid Why: This is the key step for forehead bumps and clogged pores. It goes inside pores and clears them.
I bought these products and started using them: (not daily) Cosrx BHA Blackhead Power Liquid
You'd get way better results from a leave-on BHA treatment 2-3x/week (like Paula's Choice 2% BHA or COSRX BHA Blackhead Power Liquid) than from a wash-off product.
BHA treatment beyond just the cleanser—like COSRX BHA Blackhead Power Liquid 2-3x/week on the congested areas.
K-beauty options people with similar concerns like: COSRX BHA Blackhead Power Liquid (1–2x per week for texture)
plus adding a gentle exfoliating toner like COSRX BHA a couple times a week helped so much with texture without being harsh.
I would probably keep Cosrx BHA power liquid in the am and the retinol in the pm to reduce chance of irritation.
