I recieved it from the brand for testing and was sceptical as usually calming products do nothing to my skin, but this one has surprised me. I had a laser treatment and my skin was red and it had some break  outs. I used  the serum with a cotton pad, left it on my skin for 5-10 min and it helped. Besides it has cooling effect too. Its not sticky at all, so its great to  use with other skincare products. 1 star down because I have already used half of the bottle lesss than in a month.
