Seasonal toner - FIGHTS BLACKHEADS

I love this product. I rely on this toner to deep clean my pores. During summer months in the East Coast, humidity opens my pores and the disgusting dirty air fills in... Get the picture... I don't like to see black dots around my nose and chin. This Cosrx BHA Blackhead Power Liquid works! I don't recommend using this at daytime, only use at night. I also use this on my body where I sometimes get body acne.

Too harsh

I used it only once and it gave me a sunburn into my skin. I did not see any effect besides the irritation and peeling off.

Strong, but good

If you have sensitive skin this is a good thing to use if your face reacts quickly to BHA. It is gentle enough to use multiple time a week, but don't use it every night or twice a day. I experienced peeling around my nose. While using it only 3 times a week I have noticed fewer black and white heads. My pores are visibly smaller (but not gone cause that is a genetic characteristic) and not congested either.

It actually works.

I’ve had blackheads on my nose since my teen years. I’ve tried multiple products Over the years to rid my skin of them with minimal success . This Corsrx product actually works. Since using it I’ve seen dramatic improvements. I still have some tiny blackheads, but they are much smaller and less visible. I see an improvement in skin texture too. I’ve only been using this product a few weeks. I’m hopeful with continued use blackheads will no longer be an issue for me. Best blackhead treatment I’ve ever used. The consistency is slightly heavier than water and slightly oily. It does not burn or irritate my skin whatsoever. So, I’ve been using daily rather than once or twice a week per directions. I’m not sure if this is a good idea, but I just love how effective it is, and can’t help myself from putting it on my nose each day.

I miss this product

Years ago, Cosrx stopped making this stuff because of the contents and a change in korean drug laws. I was very sad. But I recently found this site, and realozed that Cosrx went back to making this product so I bought 2 bottles immediately. This stuff is amazing.

already seeing results!

I’ve only used it about three times so far and followed the directions to use it once a week at first and I can already see a difference in my skin. My pores look smaller and I have visibly less blackheads. My skin’s overall complexion looks much smoother as well!

so far so good!

so I don't think it's been a life changer for me but it's definitely more powerful at eliminating blackheads than any other product I've used! I still have some stubborn blackheads on my nose though that aren't going away, but perhaps you have to use it multiple times before seeing all the results.

Glowing and blackheads are reduced

For starters I adore Ohlolly seriously everything on this site is curated and the owners stand by it so you cant’t go wrong with whatever you choose. I had tried weekly 2% BHA treatments in the past and find that a lower concentration more often does more for my skin. My skin is glowing, pores are smaller and my blackheads are reduced.

Black heads on my nose are gone

I followed the instructions, and after using it the second time after a week, my blackheads on my nose are gone! Needs a very small amount.

Good

I no longer have severe acne, but I switched to BHA because I have issues with blackheads and clogged-large pores. I do think this has helped. I was using the AHA exfoliatior before this one. The BHA did cause me to break out because my skin was going through a "purging" stage. After a month of adjustment, the acne resided and my skin healed pretty well. The product is good just be aware that it may cause your skin to flare up.

Literally not a single blackhead left on my face

This is the best skincare product I have ever used. Period. I have written rave reviews for a few other products on this site because Korean beauty literally changed my life, but this one specifically knocked me right off my feet. Literally the first night that I used it, all of the acne on my face that was in the process of healing was completely flat. Like this stuff made my skin skip a week of healing overnight. Absolutely insane. Over the course of a week, every single blackhead on my face was completely dissolved and erased. I have had hormonal cystic acne plus T-zone blackheads for over 10 years, and this product cured it all in one week. This product is straight up a miracle. I will never stop using it as long as I love and its still made.

Excellent texture, good for sensitive skin

I switched to this from the harsh exfoliating pads my dermatologist recommended after they started itching/burning and I couldn't be happier. I also prefer this to the Paula's Choice 2% BHA. Although I've only tried a few, this is my favorite exfoliant! I use it two to three mornings a week directly after washing and wait about 25 minutes to apply my sunscreen moisturizer so that my skin's pH can renormalize. I've had a little purging but nothing too crazy. Over all I'm a very happy camper.

AMAZING

This product is honestly the single most important part of my skin care routine. It cleared my skin so effectively and gently (I had tons of breakouts on my forehead and cheeks) I use this product in conjunction with the AHA 7 from CosRx and my breakouts reduced within three days and are now completely gone. 100% worth the money. I would honestly pay five times the amount for this product.

Bye bye blackheads

I’ve been using this for a few weeks and I swear it looks like my blackheads are slowly melting away. This product is gentle and surprisingly works!

Decent bha

I had already been using a different bha before I started this one, so I can't really vouch for it's ability to unclog pores. But I *can* say that my pores didn't get worse when I made the switch to this brand of bha, despite it being gentler than the other brand. I also really like that this bha gets absorbed into my skin super fast, and I appreciate not having to wait around forever for it to sink in.

Blackheads Gone!

I have always struggled with tiny blackheads on my nose and this product as cleared them right up while improving the overall quality of my skin. I normally have sensitive skin and was scared to try BHA but I had no issues with this product. I started using it twice a week and now use it every other day.

Seriously mind-blowing

I have had black heads on my chin and nose for 12 years (since I was 14). Literally overnight my blackheads were reduced. I could physically feel them being more flush with my skin and more cleaned out when I touched my face. I have super sensitive skin (rosacea and eczema among other things) and I have not had flare ups or break outs since using it. I haven't found my skin being irritated by the BHA. My skin feels smooth and moisturized after each use. I have been using this stuff for about two weeks and I'm already experiencing the clearest skin of my adult life. Pure magic in a bottle.

anti-inflammatory but drying

This is a high-quality BHA, which from my experience is on par with (if not superior to) the Paula's choice BHA in terms of efficacy. The anti-inflammatory properties are fantastic, as I have already used it to spot-treat some pesky nodulocystic acne on my chin. It definitely sped the process of healing along, and even stopped the progression of one in its tracks; however, I am now left with peeling/flaking of my skin in those areas. I, like some of the other reviewers, have also tried using this as part of the fifty shades of snail/Liah Yoo method for reducing the appearance of sebaceous filaments... with minimal results, but that is probably because I am less prone to comedonal acne and sebaceous filaments than I was in my early 20s. This method may work better for people who have that gritty/sandpapery type of non-inflammatory acne. All in all, I will probably purchase again since it is an affordable and effective spot treatment for my skin type.

Best serum for calming and reducing breakouts.

I've been on the hunt for the best product that. claims to help pimples and breakouts and I find this one to be the best at calming and helping the recovering process. Plus, it's really hydrating as well. Which is a plus. :)
