I've only used this once so far and the difference in my skin after one use was incredible. I already had a noticeable reduction in blackheads.

I am using this product since last year and my skin is really clear, i don't get pimples and my blackheads are smaller ! i put this on my skin every night and it hydrates my skin and leaves it smooth and it has a good smell !

This is so gentle and non irritating. It doesn't leave your face overly dry or contain any harmful ingredients. This is also Malassezia safe which is amazing since most skin care products at least have glycerin. Cosrx definitely nailed it on this one. Contains Willow bark instead of water as first ingredient.

I don't use this for blackheads but instead for angry red cystic acne that have not surfaced. It really helps to bring the pimple to a head.

Though it does leave my skin sticky, I do recommend this at night only! My skin is combination oily on the T-Zone. Blackheads a lot on the nose! This does the most amazing job for my nose. I wear a lot of make up and the primers tend to clog up the pores therefore blackheads do form. This does it job to treat it !!!! Love it

I had acne and black spots since I was 9. A year ago I introduced this product on my korean routine beauty, and ITS SIMPLY MAGIC. At first, I dindn't noticed any change, but progressively, you will note that you have less and less blackspots. Now, one year later, it's the third time I'm buying this product. No more to say. It worths every single penny.

I love this power liquid. I used this after the toner from the same brand. After using this combo i started to noticed that i have less breakouts and my acne scars are quite fading. I also noticed that i have less blackheads and whiteheads. It's watery, with a bit of smell but not prominent it will be gone after a few seconds, not sticky and doesn't sting at all. God for oily acne prone skin like me. Definitely would repurchase and highly recommend this.

I have oily acne prone skin. This has helped me to get rid off the blemishes and acne scars. My skin is so soft and smooth after using this. Remember the sun screen when you are using this!

Love this treatment! It really does dissolve blackheads, way better than ripping them out with a Bioré strip or one of those awful black masks.

I really crave this product. My closed comedones finally are disappearing using this product three/four time a week. I have a really sensitive skin and this product doesn't irritate and doesn't cause redness. A must-have in every beautycase!! After finishing the cleansing step, apply the toner, wait until it dries and then use the cosrx's BHA. Wait at least 20 minutes before to apply the rest of your routine.
