If I could give this cleanser 0 stars I would.

CONS
* Even though I have oily skin, I found this extremely drying. If you're after a foaming cleanser, there are tons of much gentler yet more efficient ones on the market.
* Not sure what ingredient in this caused a reaction (perhaps petrolatum?) but it left me with TONS of closed comedones all over my face, which has led to quite severe acne that I'm now on antibiotics & adapalene for. I know it is down to this product due to the fact it was the only new product I adopted into my routine, and I had no external factors change. I'm still suffering months down the line with cystic acne, and pigmentation as an adult.

PLEASE AVOID IF YOU HAVE ACNE PRONE SKIN - IT'S NOT WORTH THE RISK

I formerly owned a foaming cleanser by Klair's and I bought this one after watching a video with Dr. Dray on youtube where she recommended this product combined with their cleansing oil. I know for a fact that this is the product that I found sensitizing as my routine hasn't changed otherwise.
I have normal to combination skin, so before using this I didn't really have many skin concerns.
Not only did this dry my skin terribly, leaving me with scabs all over that look really funky under makeup and really itchy irritated skin but also the so called "unscented" line in fact smells like white glue (YES THE ONE YOU USED IN ELEMENTARY SCHOOL), which to me is unbearable.
I'll stick to Korean brands from now on and will not venture into Japanese.

Great gentle and hydrating wash. Love the foam, it's pretty compact, and I only need one pump for the entire face. It's not scented, and doesn't cause me any problems. I love it, this is by far my favourite wash. It leaves the skin smooth and clean, but not dry.

A light and foamy cleanser with low ph of 5.5, which makes this perfect as am cleanser and/or second cleanser for double-cleansing routine. My skin feels refreshed after without those tight, squeaky-clean feeling. I also love that's it comes out as foam - it feels much gentler on my skin and I don't have to spend some time foaming it up myself with my hands. One pump is enough for entire face.

Unfortunately it caused me some tiny bumps within 1 week of using, which is quite a bummer since it's considered as HG cleanser among ABers. I end up giving the cleanser away to my friend (who absolutely love the product). Still, ymmv.
