I did my first peel last Wednesdat. I did two layers and left it on.( a Jessner chemical peel will neutralize itself you do not have to wash it off.) I didn't get the results I wanted. So a week later my sister in law ( which is a esthetician) told me I could do it again. this time I did it the following week on a Tuesday night. I did four layers this time waiting 2 minutes in between. After the fourth layer, yes it was unbearable and was stinging, I waited 15 mins and put lotion on. The first day was face looked wind chaped and red. The second day was really tight and dry. Today is the third day and its beginging to peel. Its already starting to look good. Im excited to see what the next days have in store.
