Hoemany ml is thecosrx bha blackhead toner

The COSRX BHA Blackhead Power Liquid is packaged in 100 ml, a standard, long-lasting size ideal for trying the product. This amount lets you evaluate results over several weeks with a conservative routine. Start with 1–2 drops on clean skin at night and adjust only if your skin tolerates it well.

The toner relies on a BHA-based formula that exfoliates inside pores to dissolve excess oil and dead skin cells, reducing blackheads. A balanced, skin-friendly pH supports effective exfoliation while minimizing irritation, helping pores look smoother over time.

Beginners start with 1–2 nightly applications per week, applying after cleansing and before moisturizer. Pros can use 2–3 times weekly if tolerated, always finishing with sunscreen in the day. Avoid layering with strong actives on the same night to prevent irritation.

Patch test on a small skin area for 24–48 hours before full use to check for irritation. Avoid combining with vitamin C, niacinamide, or other exfoliants on the same night unless your routine is well tolerated. Store in a cool, dry place away from direct sunlight to preserve efficacy.

Oily and combination skin with visible pores or blackheads typically see the best improvements, along with those seeking smoother texture. Expect gradual changes in clarity over several weeks with consistent use and proper sun protection.

Avoid over-exfoliating by using the product too often or layering too many active acids. Don’t skip sunscreen, as BHA increases sun sensitivity. If irritation occurs, decrease frequency or pause use and reintroduce gradually. Apply to clean, dry skin and wait before layering other products.
