COSRX BHA Blackhead Power Liquid is an exfoliating treatment designed to minimise blackheads and improve skin clarity. With regular use, it helps reduce the appearance of blackheads and refines pore size, leaving skin smoother and clearer. Its gentle BHA (beta hydroxy acid) formulation is ideal for tackling congestion without over-drying or irritating the skin. 
It also helps skin to rebuild its moisture shield. Niacinamide allows tackling dark spots caused by acne and hyperpigmentation. 
COSRX BHA Blackhead Power Liquid provides a noticeable improvement in skin texture by reducing blackheads, refining pores, and promoting a more balanced, clearer complexion. It leaves skin feeling refreshed, smooth, and visibly brighter over time, making it a great addition for oily or combination skin types looking to control congestion. 
Please make sure you will follow the below guidance:
Must be used with sunscreen in daylight.
Do not use BHA products if you are allergic to aspirin.
Do not use BHA liquid with any other highly concentrated AHA, BHA or Vitamin C products.
Size: 100ml

Due to having Oily skin I need to use BHA toners at least twice a week. I've tried so many from cult favourite Paula's choice BHA to Glow Recipes BHA toner and sadly this one doesn't compare to those two. This is definitely a more gentle BHA and perfect for those starting to use a BHA exfoliator.

Ive heard a lot of great things about this product for a few years now but only got round to buying it recently. Ive only had one chance to use it because Im starting with once a week and will slowly increase my usage. I cant really say if its effective yet but the morning after using it, there was a bit of skin peeling on my palms (I didnt bother with cotton wool) so hoping that this is a sign of how effective it is at exfoliating! Couldnt give it five stars because I havent used it for long enough.

Just started to use but I must say Iove the way my skin felt afterwords. I've combination skin and anything that's too harsh breaks me out even more, cause of my sensitive skin this helps me exfoliate without irritating my skin and unclog my pores especially around my T-Zone.

Having had 36 years of oily / combination skin, this product is a game changer. I have been using this now for over 2 weeks and I have noticed that my skin is less oily during the day, I have fewer blackheads on my nose and my complexion is looking even. I use it daily and apply it to my face like a serum. It is a watery texture which absorbs into your skin quickly and dry with a soft texture. No sticky residue. Full recommend this product.

This is a must have for anyone who is suffering from acne, oily skin, acne scars, blackheads and hyperpigmentation. I'm pretty new to k beauty, stumbled upon this after going through tons of recommendations from beauty influencers on YouTube. Im 40yrs old and still battling with acne, and I've been through accutane treatments as well as many other alternative medicines. Started using cosrx products after so many great reviews and I'm amazed! Spent so much money on expensive products and nothing has come close to healing my skin as the cosrx range has. I've built myself up to using this once a day (used this more than recommended in the beginning as I was used to chemical peels) I cleanse first, use this serum second and dont feel the need to follow with moisturiser as it's amazing at keeping the face hydrated. On days I do feel dry I may dab on the ultra hydrating moisturizer which has birch sap which is another amazing product. My make up goes ontop so well. I dont even bother to use primer on my acne craters anymore! And its stays put all day! The key to not getting too dry (this product could do that) is finding a good moisturising routine for the night time, I would not recommend using this twice a day every day. On a night time i use the cosrx propolis range toner, iunik propolis serum, followed by cosrx propolis cream. I have used these products for 2months now and the results are AMAZING, my hyperpigmentation is a lot better, I hardly break out and if I do it doesnt last long and scars fade and heal quickly. I wish I had taken pictures in the beginning but I eally didn't think after everything I had tried that this would actually work! K beauty is the future in skincare and it doesn't get the hype it should, it's no frills packaging, reasonable pricing and basic natural ingredients is what makes them unique. So many acne products have so much s**t in them. You won't regret chucking out every product you own and replace them with korean products.

I love this product! I did a lot of research before purchasing but glad I ended up choosing this product - I have only used it once but had very visible improvements of blackheads on my nose (I took before/ after photos!). Next time I use it I'll use slightly more product on the cotton pad and leave on my nose for a couple of minutes - rather than just brushing over my nose as suggested on pack. Great service by SKINSIDER too! Can't complain :)
