Glycolic Formula 15%

Love this product. I've used it for several years. People guess my age 10-15 years younger than my real age.Go Therapy Systems!

This stuff is awesome -- really produces a dramatic difference in the quality of my skin. I literally glow (in the best way) using this. It helps to exfoliate your skin and reveals the nicer skin underneath. I love this stuff. But I took one star away because in some bottles, after a while this loses its "creaminess" and becomes almost liquified. But it still works even in liquid form. It's definitely the best product I've used in that it makes such a difference in how my skin looks.

Love this product!

I've only been using this for 3 days or so...but already my skin has been transformed! You can actually FEEL it working almost the second you put it on your skin! When you wake up in the morning having had it on all night your skin is nearly flawless and the softest I've ever felt!I'm so impressed with Therapy Systems in EVERY way!!Doniellevery acne prone combination skin (26 years old and STILL breaking out, TS is the ONLY non-prescription that has worked for me!)
