This is a good product. I have used glycolic acids for 15 years now. I realized that my skin has grown accustomed to 7%  so I was looking to bump up the percentage. I have used glycolic acid in all forms and I still prefer it in a toner form. Minus that personal con this serum is good. 

I've been using Glytone products for at least a decade, and my skin loves it! The Exfoliating Serum 11 is what I use every day to keep my skin clear, hydrated, and youthful looking. The Glycolic acid really helps with my continuing efforts to remove the dead surface layer, exposing younger cells beneath. I couldn't be with out this product!

I started using this line by beginning with the Glytone 10% lotion. I also began using the Glytone Gel cleanser for my face. I have used a moisturizer after applying this. I used it every other day for one week, then usually every night. So I decided to try this Glytone 11% lotion. I know it isn't a big step up, but the next level is 15%, so I wanted to stay safe in the sun. I like this lotion. I can use it everyday and it doesn't peel or dry my skin. I love this to use on wrinkles and acne. It is worth every penny. I am going to the next level, but maybe I will try the Exfoliating serum. A little amount covers your face and neck. Just wear sunscreen! I love this brand!

I have used this product for years. As a licensed Aesthetician with advanced training in medical esthetics, I can say this truly works! I was first introduced to it by a Dermatologist and have never looked back. I will use it for the rest of my life! Well worth it!

It is a great exfoliant recommended by my dermatologist. A little strong so I had to ease it in over a few weeks. But I like it because it does not irritate my sensitive skin.

This glycolic acid chemical exfoliant is a game-changer. It has truly helped my hormonal acne while also reducing fine lines. I have found the best results when I apply it and wait 30 minutes for it to fully absorb before finishing my routine with a serum and moisturizer. The only drawback I have would be the smell (smells very sour), however I would rather have a clean, fragrance-free product than one with unnecessary fragrance. Definitely a holy grail product for me.

Saw a well known dermatologist recommend this product which is safe for pregnancy so i bought it. I'm loving it so far and feel like it was a great addition to my skincare routine. It tingles a little bit when you apply it which makes me feel like its really working. I used a moisturizer and/or facial oil after.
