AI summary — 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
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

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.

I started with the one from good molecules and I’m using the one from the ordinary right now both work exactly the same !
good molecules azelaic acid used daily.
Good molecules azelaic acid is good and I find it more effective than the ordinary.
My current skincare routine is 5% benzoyl peroxide wash every other day,good molecules azelaic acid, Byoma hydrating serum, and vanicream moisturizer.
At night I USED to wash twice with the CeraVe facial cleanser, followed by the Good Molecules azelaic acid, differin gel, and then CeraVe daily moisturizer.
