I use this everyday and I am in the process of incorporating this into my daughters routine. We have just had really good results. I use this, the Cosrx AHA power liquid, vitamin c, and a retinoid product. I have a spare on standby because we seriously cannot run out of this. I use products from several manufacturers or companies but I stick to Cosrx for this and AHA.

Love this stuff. I have gone through a couple of bottles. Perfect for my sensitive skin. Definitely have seen a decrease in blackhead and clogged pores. I always have a back-up bottle. Also this has been amazing for my daughters back acne. Definitely recommend.

Psst - Thanks to kimmy I have tried this on my legs after shaving. OMG! It works SO well. Use it on areas where I get bumps and ingrowns. It is gentle enough for the bikini line!!! No seriously. It has been awesome to use this summer. Even more of a holy grail now than every before!

Waaaah!!! I'm so glad it works this well for you, too! It was such a huge game changer for me. Sometimes when I use it I feel like I'm waking up from a dream to the absolute marvel of the reality of this product, all over again 😂

I lovelovelOVE this product! A staple skincare product for sure! The texture is so light and sinks in so fast! Also, my sensitive skin doesn't get irritated at all, which surprised me, after I've unsuccessfully tried Paula's Choice BHAs before this one.

Another amazing way to use this is to apply it on freshly shaved and/or epilated/waxed skin. Ever since I've started doing that (paired with occasional gentle physical exfoliation in growth-direction) my red bumps and ingrown hairs have completely disappeared. Seems like a miracle, tbh. Can't recommend this one enough.

Great idea! I hadn't thought of using a BHA after shaving. I will have to try it.

OMG I need to try this! And I am going to let my daughter know. She struggles with bumps and ingrown hairs. May be a game changer!

Good luck to you both! I apply the BHA after every gentle physical exfoliation in the shower, so about 2 to 3 times a week, and then wait half an hour before following up with a light gel-cream on top. It also works great on the bikini zone, and wearing looser clothing in the trouble-prone areas has also contributed to it all being less iriitated.

I love this so much!

That is a great idea! Gotta get my daughter to try that!

So far I like this! I’m surprised at how much it does not irritate my sensitive skin. I’m new to k beauty and am used to harsh American products wreaking havoc in order to get clear skin. This is so gentle but effective. I’m starting with only once per week and using Jude Chao’s method with clay mask and oil cleanser afterward. Must read article, too, if you haven’t!

As Sheryl said this product truly is a holy grail product, within two uses the blackheads in my nose are gone.

The BHA liquid is effective for the 3 step pore cleanse. I haven’t been able to regularly use it without washing off though as it makes my skin feel sensitive. :(

Love this product! I use it almost every morning to keep my pores clear as I'm oily/combo and am very prone to congestion. A lot of other BHA products can feel oily or greasy on the skin and this one absolutely does not. It also is gentler than traditional salicylic acid so it's great for people who are more sensitive or need a gentler alternative for whatever reason.

I use this as an active and have been using it for almost a year now. From what I've read, I definitely think it's important to use a low pH cleanser beforehand if you want to maximise the results. I also use a pH adjusting toner before to make sure my skin is prepped. I don't use cotton pad with it. Instead, I just pump it into my palm and spread it onto my face. I leave it for about 20 minutes for it to do its job, and then I continue on with the rest of my routine (hydrating... Read more

I have blackheads on my nose and the sides of my nose and chin are sensitive so I'm careful while using this because it can irritate the skin. I use it every other day, sometimes 2 days straight depending on how my skin is acting. I use this every time I do a peel off mask on my nose!

I have just ordered this product after reading so many good reviews... can't wait to see if it really help with blackheads.
