It certainly helps calm down acne quite fast. Also lightens acne scars and other skin hyperpigmentation. Generally, the product itself works for acne/troubled skin. The only reason why I'm giving this great product 4 stars is because the consistency is like a thick sunblock. Sticky and kinda tight to the skin. It doesnt like "set" to the skin fast so you have to pat and wait till it get less sticky. Yeah, the stickiness won't go. So I only use it at nightime. 

Reduces redness quickly and helps heal faster 

The amount is very little for the price. Yesterday I received my order and I use it for the first time,I noticed some of my pimples were reduced and some of the redness have dissapeared. It has a very slight smell of tea tree oil and when you apply it has a very little cooling effect but it dissapears. I wish they could have a bigger version of it.
