That quest for a poreless, glass-like complexion can feel endlessly frustrating, especially when stubborn blackheads and congestion seem immune to your current routine.

The journey to find the perfect exfoliant is riddled with potential pitfalls. You’re searching for a formula powerful enough to deeply purge pores and dissolve the glue-like sebum that causes breakouts, yet gentle enough to avoid the dreaded tightness, redness, or moisture barrier compromise. There’s nothing more disheartening than investing in a product that promises a revolutionary clear-out, only to be left with skin that feels sensitized, stripped, and looking exactly the same as before. This cycle of trial, error, and disappointment makes the search feel both overwhelming and futile.
Fortunately, your search ends here. We’ve undertaken the meticulous research and comparative analysis so you don’t have to navigate the crowded market of Korean BHA brands alone. This comprehensive roundup cuts through the noise, breaking down the top-performing toners, serums, and liquids from beloved brands.

Buyer’s Guide: 3 Key Factors to Consider
Skin Concern & Formula Focus
Identify your primary goal. Are you targeting stubborn blackheads or overall acne and texture? For intense blackhead focus, a formula like the COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner is ideal. For a multi-acne solution that includes cleansing and moisturizing, a system like the SOME BY MI 30 Days Miracle line is more comprehensive.
Skin Sensitivity & Exfoliant Strength
Know your skin’s tolerance. BHA (Salicylic Acid) is great for oily, acne-prone skin, while AHA/PHA are gentler and help with surface texture and hydration. If you have sensitive skin, a milder introductory toner like the COSRX AHA/BHA Treatment Toner is a safer start than a high-potency formula.
Product Type & Routine Integration
Consider where the product fits in your routine. A toner is a versatile first treatment step, a cleanser offers a non-irritating wash, and a cream provides lasting treatment and hydration. For best results, you might use the SOME BY MI Acne Clear Foam and SOME BY MI Miracle Cream together for a consistent, targeted approach.
Frequently Asked Questions
Q1: Can I use a BHA product every day?
A1: It depends on the product’s strength and your skin’s tolerance. Gentle formulas like the COSRX AHA/BHA Treatment Toner can often be used daily, but potent exfoliants like the COSRX Niacinamide + BHA Blackhead Exfoliant should be introduced slowly, starting with 2-3 times per week.
Q2: What’s the difference between AHA, BHA, and PHA?
A2: BHA (Salicylic Acid) is oil-soluble, perfect for clearing pores and blackheads. AHA (like Glycolic Acid) exfoliates the skin’s surface to improve texture. PHA is a larger, gentler molecule that provides light exfoliation with extra hydration. Products like the SOME BY MI 30 Days Miracle line combine all three for a multi-action effect.
Q3: Will these products make my skin purge?
A3: It’s possible when first using chemical exfoliants, as they accelerate skin cell turnover. A period of increased breakouts (purging) for 2-4 weeks is normal, especially with targeted treatments like the SOME BY MI Miracle Toner. If irritation or redness occurs, reduce frequency.
Q4: Can I use these BHA products with other actives like retinol?
A4: It’s best to proceed with caution. Using strong BHA products and retinol together can compromise your skin barrier. Alternate them on different nights, or use your BHA toner in the morning and retinol at night. Always listen to your skin and prioritize hydration.
Q5: Are these Korean BHA products suitable for sensitive skin?
A5: Many are formulated to be gentle. Look for products with soothing ingredients alongside the exfoliants. The COSRX AHA/BHA Treatment Toner is a great mild option, and the SOME BY MI products often include calming ingredients like tea tree and snail mucin to balance the exfoliating acids.
Final Verdict: Which One Should You Buy?
Our top pick for a dedicated, powerful treatment is the COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner for its focused efficacy on blackheads and congestion. For a holistic acne-care system, the SOME BY MI AHA BHA PHA 30 Days Miracle lineup—especially the Toner and Cream used together—is the best choice for managing breakouts, oil, and texture while maintaining skin comfort in 2025.
