“Been using for a week. So far so good. Was a little intense the first couple days I used it with slight redness & flushing but that lasted only a minute or two. I haven’t had an issue since day 2. Only downfall is the dropper is poor quality. It doesn’t release a lot of product, so a lot is wasted in the dropper that won’t come out. Expensive product to have a lot wasted and stuck in the dropper.”
