This product contains 0.5% salicylic acid that is supposed to target acne, but I feel that 0.5% is too little of a concentration to actually make a noticeable difference on any pimples. Usually, I use 2% and that works perfect, but because it is Shiseido and I'm a sucker for any new Ibuki products, I had to try it. I was actually very surprised to find out that the product itself is tiny! It's 30 mL. I purchased it thinking that it would be the size of a Cinique moisturizer jar, but nope! Just be careful ladies, to properly read the size before you buy it! In terms of treating acne or anything else on my skin, it doesn't really do anything for me, except provide a cooling sensation when applied (it is a gel formula) so it would be good for the summertime.
