Query: Wonderful product

This is a great product, I have used glycolic acid for years ( lower doses) this did not sting or burn for me , I did not even have to nuetralize it ( water only) I loved the sample they sent also!!! If you go to there web site & read the tags you can learn alot. Very impressive company!!! This is good to use as a break from stronger peels. ( no pain!!)
