I've tried 2 of her products. -- Kate in a Jar (KIAJ) and the Enzyme Scrub & Mask (ESM). People raved about KIAJ so I tried it. It was OK; I had to watch a timer to make sure that I didn't keep it on too long -- there's something in it that gives a strong burning sensation. I didn't repurchase it. The ESM is supposed to be a milder version of KIAJ. It worked well, but was not worth the money for me to repurchase.
I know people rave about some of the products, but those are the only 2 that I tried.
