my skin is not particularly acne-prone, but i have tiny pores and so i'm very prone to closed comedones. now that i've used this product, i don't think i can be without it!

BHA's are great for closed comedones because they are able to penetrate oil on the skin and get deep into the pore to clear it out. since it penetrates even thick oil, it stops debris from collecting inside the pores and therefore prevents buildup that causes pimples and clogged pores. i've tried other BHA's before, but my skin is so sensitive and dry that ones i've used in the past were too harsh for me, and painful to use. this one however is a completely different story. there's no sting, and not even any drying, and it helps so much at keeping comedones at bay while i use the AHA to purge what i already have. i'm really so grateful to CosRx for this, it's such a lifesaver.

-however! it's very important to use actives correctly, so please read this if you've never used them before!

to get the most out of an active like BHA or AHA and get the absolute best results, you need to use them properly.

• first of all, your skin must be PH balanced for the products to effectively exfoliate. this means wash your wash with water and then wait about 10 minutes, or use a PH balancing toner. (the CosRx BHA/AHA one is my favorite for this!!)
• apply the BHA before any AHA, and once applied, allow it to set into the skin for 15-20 minutes so to give it time to do its magic.
• if you use AHA, you can apply it after the BHA has been sitting for 15-20 minutes and then also let the AHA sit for that long. then you can go on with the rest of your routine.
• and last but not least, don't use actives daily. this BHA is super gently and i know some people who can get away with using it daily, but you don't want to risk overexfoliation. my routine is goes (Day 1) BHA only (Day 2) BHA and AHA (Day 3) No actives, use a sheet mask or moisturizing mask instead. and then repeat!
