BHA Blackhead Power Liquid, 3.38 fl oz (100 ml)

The COSRX BHA Blackhead Power Liquid is hands down one of the best products I’ve used for minimizing blackheads and keeping my skin smooth. It’s gentle but effective—no stinging or dryness, just gradual, visible results. I apply it 2–3 times a week and have noticed fewer breakouts, tighter pores, and a more even texture overall. It absorbs well and layers nicely with the rest of my routine. If you're dealing with blackheads, congestion, or rough skin, this is 100% worth trying. Just be sure to use sunscreen, as BHA can increase sun sensitivity! 🌞

I’ve been using it for several weeks, and it has significantly improved my skin. This gentle exfoliating toner combines 2% niacinamide with 4% betaine salicylate, a milder derivative of salicylic acid, making it suitable for those with sensitive skin . It has a lightweight, watery texture that absorbs quickly, leaving my skin feeling refreshed and smooth. With consistent use, I've noticed a reduction in blackheads and an overall improvement in my skin's texture and clarity .

I have been using this BHA liquid for a few weeks and I really like it. It helps keep my pores cleaner and makes my skin feel smoother. It is gentle on my skin and does not have a strong scent. The texture is light and absorbs well. I use it 2–3 times per week and noticed fewer blackheads and less congestion. The bottle size is good and lasts a long time. I would definitely purchase it again. ⭐⭐⭐⭐⭐

Excellent exfoliating toner! Helps reduce blackheads and smooth skin texture without being too harsh. Absorbs quickly and leaves skin clearer and more refined with regular use. Gentle yet effective—highly recommend!

i am intimately familiar with many a pore refining product, but i'm actually very impressed with this one!! cosrx is truly ol reliable if you will, but i notice my pores are significantly refined after using this on targeted areas each night for a few weeks (in addition to 2x per week gentle clay masks & 1-2x per month pore refining sheet mask). i use it once a day (at night) in between toner & the cosrx snail serum guy. i apply it to my nose, chin, and in between my eyebrows & let it dry before applying the next step. recommend boots

ve been using COSRX BHA Blackhead Power Liquid for a few weeks, and I can already see a difference. It helps reduce blackheads and keeps my pores cleaner. The texture is lightweight and absorbs quickly without feeling sticky. It’s gentle on the skin but still effective — no irritation for me. My skin looks smoother and more even, especially in the T-zone. I also noticed less congestion over time.

I picked this serum up to help with rosacea as the ingredients were still beneficial for my type of skin, but tbh didn’t see the difference I wanted to with this serum

It may feel slightly oily and a bit too runny at first, but it’s actually not an oil—it absorbs quickly into the skin and doesn’t leave any shine. It works wonderfully as a serum under additional skincare or a day cream. I use it twice a day.

COSRX BHA Blackhead Power Liquid has been a game-changer! It gently exfoliates without irritation, helping clear clogged pores and reduce blackheads. My skin feels smoother and more balanced after regular use. The lightweight formula absorbs easily and doesn’t feel sticky. Great quality and really effective—highly recommend for clearer, healthier-looking skin!
