I’ve been using this for about a month so far and I already ordered a replacement for when I run out. At first I wasn’t sure about it because the scent was a bit strong and I wasn’t entirely sure it was doing anything for my skin. But the more I used it, the clearer my skin became. It got to the point where the scent is something I look forward to because I associate it with the positive effects of the serum. It goes on silky, dries incredibly smooth, and dries quickly enough for me to move into my next serum immediately. For reference, I have oily skin that’s somewhat sensitive and acne prone. This has caused no negative side effects whatsoever except a slight tingling the first few times I used it (I don’t get it anymore). HIGHLY RECOMMEND TO ANYONE LOOKING TO ADVANCE THEIR SKIN HEALTH.
