love this lotion [SEP] this is the best glycolic acid lotion i have ever used i have been using face acids on my face and neck for dark spots and wrinkles for many years it feels great and it burns just a tiny bit i thought nothing could actually make my face tingle and you only need to apply a dime size i alsouse a tiny amount with my eye cream if you are not accustomed to using glycolic acid be careful with this brand it is very potent i suggest mixing a small amount with a moisterizer i do that for my neck a bit of redness and peeling is common i will absolutely order again
