COSRX Niacinamide + BHA Blackhead Exfoliant Toner 100ml — 2% Niacinamide, 4% BHA for Pore Refining & Brightening

COSRX Niacinamide 2% + BHA 4% Blackhead Exfoliant Toner is a lightweight Korean toner designed to refine pores, reduce blackheads, and brighten skin tone through daily gentle chemical exfoliation.

This exfoliant toner combines 4% BHA (Betaine Salicylate) with 2% niacinamide and willow bark water to target congested pores and surface dead skin. The formula is water‑based and low‑irritation, intended for regular use as part of an evening routine to help smooth texture and support a clearer, more even complexion. It is labeled hypoallergenic, free from parabens, sulfates, phthalates, and not tested on animals.

How does this toner reduce blackheads and clear pores?

The 4% BHA works by dissolving the build‑up inside pores and loosening surface dead skin, while niacinamide helps regulate oil and improve tone. Regular application helps prevent recurrence of visible blackheads and keeps pores feeling cleaner over time.

• Betaine salicylate (4%) penetrates oil-filled follicles to clear debris.
• Niacinamide (2%) supports oil balance and visible pore refinement.
• Willow bark water enhances exfoliation with plant-derived salicylates.
• Daily, gentle formula avoids harsh scrubbing or physical abrasion.

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

Use after cleansing and before heavier serums or creams. Apply in the evening for best results: saturate a cotton pad and gently sweep across areas with blackheads or enlarged pores; allow the liquid to absorb. Follow with targeted treatments and moisturizer.

• Use nightly or as tolerated, starting with every other night if you’re new to acids.
• Saturate a cotton pad and wipe—do not rinse off—so the active ingredients penetrate.
• Apply sunscreen during daytime after use to protect new skin cells.
• If tingling occurs, reduce frequency or apply on alternate nights until acclimated.

Is this toner suitable for my skin type and sensitivities?

The formulation is intended for all skin types, including oily and combination skin prone to blackheads. Because it uses willow bark water and a gentle derivative of salicylic acid, it aims to minimize irritation, but those with very sensitive or barrier‑compromised skin should patch test first.

• Oily and combination skin: effective at clearing and controlling congestion.
• Dry or sensitive skin: start slowly and monitor for irritation.
• Acne-prone skin: complements spot treatments but avoid mixing with strong retinoids without guidance.
• Not a physical extractor—works chemically to dissolve pore buildup.

What results can I expect and how long until I notice them?

Immediate effects often include a cleaner, less sticky skin surface and reduced visible congestion. Consistent nightly use typically shows clearer pores and smoother texture over several weeks; individual results vary based on skin condition and adherence.

• Short term: fresher-looking skin and reduced surface oiliness within days.
• 4–6 weeks: visible reduction in blackheads and smoother pore appearance for many users.
• Maintain results by continuing regular exfoliation and sun protection.
• Discontinue if persistent irritation or severe redness occurs.

Who is this for? This COSRX exfoliant toner is aimed at people who want a chemical approach to blackhead control and pore refinement without abrasive scrubs. It's suitable for shoppers seeking a gentle, daily acid toner to integrate into a K‑beauty routine—especially those with oily, combination, or congestion‑prone skin who are comfortable using BHAs and niacinamide. If you have extremely sensitive skin or are using other strong actives, introduce it slowly and consult a skincare professional if unsure.
