This was really gentle and hydrating and that's about all I can say for it. Unfortunately, this didn't seem to do much for me. I see much better results using Stridex (though less often, since it's far more potent). This was disappointing since I had seen so many good reviews and would have loved to incorporate a gentle acid to use every day.


when can i use this in my 10 step program?


I use it right after washing my face, then wait 15 minutes, then do the rest (first essence etc.).


A great blackhead product! I was skeptical about this at first, but it showed me results so quickly. My blackheads and pores shrunk majorly. It controlled the oil on my nose, but kept the rest of my face moisturized! It was the first product that I knew I could count on for my blackheads!


This stuff is a miracle worker. doesn't dry out my skin and clears my blackheads.


I've used this stuff for ages and really love it. It's gentle enough to not irritate my dry irritable skin, and helps with gentle exfoliation and removal/prevention of buildup.


This stuff is great. I apply a thin layer 1-2x a week at night and the next day my skin is smoother and softer, and when I oil cleanse all sorts of grits come out. Also it lasts forever - you don't need much per application. I've had the same bottle for months. WIll repurchase.


Agreed that it lasts a long time! I’ve had my current bottle since late May!


This is really helping control oil. I use it most days at night now and follow with Purito green level toner in seven skin method plus serum, cream, and sometimes sleeping mask. I take breaks from it for several days though post using an AHA to avoid over exfoliating.


I should add, I’ve cut back AHA use significantly to once per month and just use BHA to control oil.


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!
