Life changing

One of the first Ordinary products I tried. I have the 5%, and immediately noticed a change of texture in my skin after the first few uses. Keep in my I use this in alternation w/ other Ordinary products - this product, however, produced the most change in the texture and brightness of my skin in comparison to the other serums I alternated between. I use this 1-2x/week. I highly suggest this product for chemical exfoliation beginners, as lactic acid is more gentle than glycolic, and to start off with the 5% rather than the 10%. Can't live without it!
