COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner 100ml — pore-clearing, gentle formula

COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner is a lightweight Korean toner designed to exfoliate pores, reduce blackheads, and even skin tone with a blend of BHA and niacinamide.

This 100 ml toner pairs 4% BHA (betaine salicylate) with 2% niacinamide to target congested pores and dull texture while supporting a balanced, clearer-looking complexion. Formulated with willow bark water and gentle ingredients, the formula slips into the skin to help loosen trapped oil and dead skin without harsh scrubbing. It’s presented in COSRX’s minimalist packaging and intended for incorporation into an evening routine or twice-daily use depending on tolerance.

How does this toner clear blackheads without over-drying?

The 4% BHA acts as a lipid-soluble exfoliant that penetrates sebum-filled pores to dissolve buildup, while willow bark water and the low-irritation formulation reduce surface flaking. Niacinamide helps support skin tone and barrier function so the skin is less likely to respond with excess oil production. Many users notice smoother texture and fewer visible clogged pores within weeks when used consistently.

• 4% betaine salicylate for pore-penetrating exfoliation
• Willow bark water for natural exfoliating support
• Niacinamide 2% to help even skin tone and strengthen barrier
• Formulated to minimize irritation for regular use

When and how should I use this product in my routine?

Apply after cleansing and before heavier serums or creams. Saturate a cotton pad or pour a few drops into your palms and gently sweep over areas with blackheads or enlarged pores. Start with every-other-night use if you’re new to chemical exfoliants, and increase frequency as your skin tolerates it.

• Use after cleansing, morning or night depending on skin sensitivity
• Apply with cotton pad or fingertips, focusing on congested zones
• Expect a brief tingling; discontinue if persistent irritation occurs
• Always follow with broad-spectrum SPF during daytime use

Will this toner suit sensitive or oily skin?

Although the formula contains a potent concentration of BHA, COSRX balances it with soothing botanicals and a moderate niacinamide level to reduce the chance of over-drying. Oily and combination skin types often benefit from the pore-clearing action, while sensitive skin users should perform a patch test and introduce it gradually. The product is labeled hypoallergenic and free from parabens, sulfates, phthalates, and animal testing.

• Oily/combination skin: helps unclog pores and control texture
• Sensitive skin: patch test and start slowly to check tolerance
• Normal/dry skin: use less frequently or layer with hydrating products
• Clean formulation reduces risk of common irritants

Who is this for: This toner is a fit for anyone looking to reduce blackheads, refine enlarged pores, and smooth skin texture without physical scrubs. It’s particularly well-suited to oily and combination complexions or those beginning a chemical exfoliation regimen who want a product that pairs targeted BHA action with niacinamide’s balancing benefits. If you are using retinoids, have very reactive skin, or are pregnant, consult a professional before adding active exfoliants to your routine.
