Review (4/5): I've only used it once so far....
I personally have not had any reactions, and I have sensitive/rosacea skin, and it's been ok thus far (only have used it once since it arrived this morning. I know others have mentioned their concerns about how much product is actually in the tubes, and the only one I noticed that was about half full, was the serum. Everything else seems to be full, but only the serum was sealed with the silver foil.
Since the 1 oz spray face mist sells for $18, this was a total steal because you get 5 products for only $2 more. Plus you get to try out all the other products to see if you like the consistency of them. This set originally is supposed to be $46, but it's on sale right now for $20 on here, as well as their website. So, I couldn't resist the good deal.
