COSRX BHA Blackhead Power Liquid is a leave-on exfoliating treatment made for blackheads, clogged pores, excess oil, and rough skin texture.

It uses betaine salicylate, a BHA ingredient, to help clear dead skin buildup and sebum inside the pores. The formula also includes willow bark water and niacinamide, making it suitable for oily and combination skin that needs pore care and smoother-looking texture. Product listings position it for blackheads, dead skin cells, sebum, pore congestion, and oil control.

For Routisca, this should be treated as an exfoliating treatment, not a daily toner. It is best used slowly at night, especially for users who already understand basic skincare.

Made for this climate

Why it works in Bangladesh

Good fit for oily and clogged-pore skin in Bangladesh’s humid weather because it targets excess sebum, blackheads, and pore buildup. Not ideal for over-cleansed, dry, or damaged skin.

Application

How to use it

1 Use at night after cleansing and toner.
2 Apply a small amount to areas with blackheads or clogged pores.
3 Start 1–2 times per week, then increase only if your skin tolerates it.
4 Follow with moisturizer.
5 Use sunscreen every morning while using exfoliating products.

Routine placement

Where it fits

Night: Cleanser → Toner → COSRX BHA Blackhead Power Liquid → Moisturizer

Use only a few nights per week. On other nights, keep the routine simple with cleanser, hydrating toner or serum, and moisturizer.

Morning after use: Cleanser → Moisturizer → Sunscreen.

Realistic expectations

What to expect, and when

Week 1 to 3

You may purge — existing congestion surfaces faster. This is normal and passes.

Week 4

Blackheads on the nose and chin visibly reduce.

Week 6 to 8

Pores look smaller and skin feels smoother.

Start twice a week, not daily. Going too fast is the single most common reason people give up on this product.

Good to know

This might not be for you

Avoid if your skin is very dry, very sensitive, peeling, sunburned, or barrier-damaged.
Do not use in the same routine with other strong exfoliants, retinoids, or harsh acne treatments at the beginning.
Not ideal for complete beginners unless introduced slowly.

Authenticity

How to know it's genuine

Sourced through verified importers, never grey-market resellers.

Genuine COSRX bottles carry a laser-etched batch code on the base. The liquid is clear and slightly viscous with a faint natural scent from the willow bark — that smell is normal, not spoilage.
