I get Keratosis pilaris aka chicken skin on my upper arms and sometimes upper thighs. I also get ingrown hair shaving my bikini area and sometimes on my legs. I started using the lotion and within a week my arms were almost clear. Then at 2 weeks my arms were softer than I’ve ever felt. I’ve had KP since I can remember. Sometimes it got so bad it would form clusters, after I got it under control I had a lot of little red scars from where the bumps were so I decided to take it a tad bit further and try the glycolic acid serum from same brand. 2-3 nights a week I take a hot shower and get everything soft and pores open and sparingly apply it to my arms upper thighs and bikini zone. My skin sucks this serum in almost immediately and then I apply the lotion. On the nights I don’t use the glycolic acid lotion or serum I use a body lotion with retinol in it. I can happily say my arms are free and clear without KP bumps, no longer get ingrown hair on my legs or bikini area and my skin is so soft I get compliments all the time. I had a nurse put her hand on my leg during a medical procedure and she had to know what I was using to have such soft toned skin. This is my holy grail and I hope they never cancel these two items. If you’re second guessing if you should purchase these products just start with the lotion. You might not even need the serum.
