A great simple, skin balancing cleanser! Doesn't dry out my skin and is perfect for when my skin is finally back to "normal" after a bad breakout and I want to switch from a salicylic acid cleanser to a more gentle cleanser.


Old time favorite -- cleans well and leaves your skin feeling clean, not stripped, and honestly, this is one of the OG low pH cleansers after SU:M37's Rose Cleansing Stick (peeps, when BT was W2 Beauty, that was crazyyy sold out) -- fortunately, I can say this cleans better for my skin than the RCS, and it's in a squeeze tube, which is great for my laziness in the shower.


I went to the store multiple times looking for this cleanser because of all the great reviews but they were always sold out until one day! Super gentle cleanser, I use it everyone morning and my skin feels squeaky clean without drying my face. Glad I was able to get my hands on this cleanser


I'm glad you were able to finally get this! Its an HG for me!


This cleanser is very mild but cleans really well. It doesn't foam up a lot compared to the other cleansing foams. I love how this cleanser doesn't strip away the natural moisture from my skin. This is always my go-to cleanser!


I have dry skin so many cleansers make my face feel like tissue paper, but not this one, this one doesn't dry out my skin at all, and reduced my breakouts. Love this cleanser.


I love this cleanser. I have sensitive and combination skin. This cleanser doesn’t irritate my skin, break me out, and it doesn’t strip my skin of its natural oils and moisture. Hands down my favorite cleanser and I’ll never use anything else.


Woo-hoo for the holy grail! This was the first cleanser I switched to when I first learned about low pH cleansers, and I haven't looked back! Yes, I also like the Innisfree 5.5 Blueberry Cleanser, and I even dabble with a slightly higher pH cleanser (6.5-7) for the summer when my skin gets super oily (gasp), but I will always have a backup COSRX Low pH Cleanser in my bathroom. It's just so reliable and so good; it never strips my skin, it leaves my skin feeling hydrated but clean, and I personally love the tea tree smell. I plan... Read more


Great product!
