This product is amazing, I am planning to buy this again as soon as I'm running out. If my acne starting to form and started to get red and irritated, I just put this on at night and the next morning the pump around my acne got reduced and under a week or so the pimple went away. 
This is some magic voodoo stuff I swear :D

​I use this paired with the COSRX Blemish Ampule, as per a lot of recommendations and i think it works. For 30 ml it looks like a lot of product and I'd say that a little goes a long way with this cream. Don't scoop out too much (use like half a pea size) or you'll be using this cream as your moisturiser. Things I don't like about the product are that it's in a tub (prone to contamination from outside air), and I know that they've provided a spatula for more hygienic use but one: it's massive for a blemish cream, and two: I still prefer a squeeze tube packaging as it just seems more sanitary.  

this is such a great cream for acne!
