I purchased the Jessner through my facialist. She gave me a "hook up". She explained how to use it. I was good to go. I had a photoshoot with a friend due in a few weeks and thought this would be great to do beforehand. WRONG. I had MAJOR peeling. It stings like the dickens.
I had so much heavy peeling. it works. My skin looked great. I applied Aquaphor daily to keep myself from ripping off large chunks of skin (this is a no-no). I no longer use it as a peel, since I use ascorbic acid (vitamin C powder). It gently turns cells and is easy to use. No peeling. No downtime. No stinging.
I do however use the Jessner with a Q-tip and apply it direct on those nasty under skin zits. Brings them up fast or gets rid of them completely.
