Brand new and in-date! This replaced the green science peel kit. Its a 2 step thermal peel. This is the same peel as at the salon. Professional sized. Best price anywhere! I have a few sets and could bundle if interested. Message me. Price firm. To use: evenly apply base to clean face (i use it in shower), apply activator, wait 10 minutes and rinse. I rewash my face afterwards and continue usual moisturizing regimen.
