Be ready to have a red face but this is the genuine product as experienced at the salon. Depending on your skin you might experience a very light peel effect the next day. The redness takes an hour or so to fade. Love this stuff! But it is strong! Don't use a lot, and keep it on a minimal amount of time. It tightens, smooths pores, and gives you a glow. Yes, it's expensive, but you need the tiniest amount and the tub will last a long time time. Just do it, and you're welcome!
