I use their Lactic Acid and Mandelic Acid to treat melasma (facial discolorations). Their products seem to be good quality and reasonably priced. I plan to try a TCA peel in the next month!
I've repurchased their glycolic peel and TCA peel. I've bought a sample of the facial scrub and it's *okay*. Still need to use the decongestant mask to see if it does what it says. I love that in each order, I've received a free sample of something else.
