Hi, I'm a 55 year old female and have had great success using glycolic acid for my face. Over the past few months I have been routinely (almost daily) using a 14% body lotion (another brand) for spots of seborrheic keratosis on my back and torso, with very limited success. I would like to try using the 50% glycolic acid peel for SK, and wanted to ask if you had any special recommendations for using it for this purpose. Should I also follow the recommended regimen on your website (once per week for 6-8 weeks, followed by 4 weeks off), and also if I should continue using lower concentrations of glycolic acid body lotion between peels. I greatly appreciate any help you can provide! Thanks!
