COSRX BHA Blackhead Power Liquid 100ml

COSRX BHA Blackhead Power Liquid 100ml is a Korean liquid exfoliant designed to help unclog pores and reduce the look of blackheads, making it a practical addition to any routine focused on clearer skin. The formula centres on salicylic acid, a beta-hydroxy acid that works inside the pore lining to dissolve excess sebum and dead skin cells that build up in Bangladesh's year-round humidity. This makes it especially useful for skin that tends to look congested or bumpy under the face and nose area.

What is COSRX BHA Blackhead Power Liquid 100ml and how does it work

COSRX BHA Blackhead Power Liquid 100ml is a leave-on liquid exfoliant that uses 4% salicylic acid to help clear and refine the appearance of enlarged pores and blackheads. Unlike surface-level scrubs, salicylic acid is oil-soluble, meaning it can penetrate the pore lining where it gently breaks down the mixture of oil, dirt and dead skin cells that form a blackhead. The formula also includes niacinamide, which helps calm any potential irritation while supporting the skin's barrier, and witch hazel extract, traditionally used to help mattify and soothe oily zones.

Best for

• Oily skin that looks shiny by midday, especially across the T-zone
• Frequent or stubborn blackheads on the nose and chin area
• Enlarged pores that appear more visible under humid conditions
• Skin prone to whiteheads and mild congestion
• Combination skin that needs targeted treatment on oily zones only
• Mature skin showing early signs of clogged pores along the sides of the nose

COSRX BHA Blackhead Power Liquid 100ml is generally well-tolerated, though very sensitive skin should patch test behind the ear or on the jawline before full-face application, particularly if you are new to chemical exfoliants.

How to apply it

1. After cleansing, pour a small amount (about the size of a 5p coin) into your palm or directly onto a cotton pad
2. Smooth evenly over the T-zone and any areas prone to blackheads, avoiding the immediate eye area
3. Use once daily in the evening to begin with, building to twice daily if your skin tolerates it well
4. Always follow with a moisturiser suited to your skin type to maintain barrier balance
5. In the morning, apply sunscreen to any treated areas — salicylic acid can increase sun sensitivity, and Bangladesh's strong UV makes daily protection essential

What to expect over time

Results from COSRX BHA Blackhead Power Liquid 100ml are not instant. With consistent use, you may notice fewer new blackheads forming within two to three weeks, while existing ones gradually soften and clear. Pore appearance often refines over four to six weeks, though this depends on how congested your skin was to begin with. The lightweight texture absorbs quickly without residue, making it easy to keep using through humid months when heavier products might feel uncomfortable. Like all skincare, the best outcomes come from patience and daily use rather than expecting dramatic overnight changes.
