Let me tell you that the box is soooo elegant. It designed so that the bottle inside wont move. It's super safe.
Based on its ingredients, this spot treatment is a dupe of mario badescu. This spot drying treatment claims to 100% reduce acne lesion redness in 8 hours and 73% reduce acnes in 3 days. And yeah, the former claim is true. Within 8 hours, I can see that my redness calmed down. And within 3 days, few acnes, approx 2 out of 4, were gone. For me, this results aren't that satisfying. I kinda hope that it can fully heals acnes.
Oh they also wrote a side effect warning inside the box. It is written as following, "when using this product, you may feel stingin at the beginning of application... blablabla." However though, I didn't experience any stinging sensation, instead upon application, it feels really cool and I like it.
