Glycolic Acid Facial Cleanser My thoughts about it: wow for sure! My face did in fact feel silkiness afterwards. A+ Who doesn’t love a softer looking face, especially if you are starting to have a few fine lines.  You splash your face with cold water and then next I used their Glycolic Acid Facial Toner My thoughts:  I have never been really big on using toners, they are always so drying and made my face itch.This was the first toner that left my face feeling soft. I was now ready for the next step which was 5% Glycolic Acid CreamNow Reviva Labs Glycolic Acid creamcomes in two different strengths 5% and 10%. If you ever had a facial done that Glycolic Acid lotion or cream was used it was probably closer to 10%. But for home use 5% Glycolic Acid is great to start with till your face gets used to it after a few months then you can move up the 10% Glycolic Acid Cream. My thoughts:   Yes in fact it does have a slight stinging sensation which is normal. I just used their Hyaluronic Acid Serum and it really made a difference in how my face looks in the morning.  This is one of the most amazing serums because it feels like gel, but it smoothes in and your skin just soaks it up.  I just used their Alpha Lipoic Acid, Vitamin C Ester & DMAE Cream as my night cream.
