AI summary — not a quote
BHA exfoliants are highly recommended for their ability to clear inside the pores and manage sebaceous filaments. Users emphasize that while the product is effective for resurfacing, consistency is more important than frequency, with most suggesting a limited application of one to three times per week.
Pros
- Effectively clears inside the pores
- Helps reduce the appearance of sebaceous filaments
- Acts as an effective chemical resurfacing agent
- Works well as a supplemental treatment in routines containing niacinamide or oil cleansers
Cons
- Potential for irritation if used daily or too frequently

Once a week, use BHA exfoliant with clean cotton pads.
Regardless of that I would get started on a good skin routine of cleanser/BHA exfoliant/Vitamin C serum/moisture/sunscreen and peptides/retinol/moisture at nights.
✅ BHA exfoliant 2-3x per week
✅ BHA exfoliant — Clears inside the pores
niacinamide, salicylic acid, benzoyl peroxide (face wash, not just on pimples), bha exfoliant (weekly), and oil cleansers help a lot.

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.
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.
