I have 2 daughters, both of whom have kp on the face as well as arms. My older daughter went through many dermatologists who kept saying it was acne. Eventually, she went on accutane and it all cleared up. 6 months later it came back on her arms, but face is relatively still clear. Younger daughter has the same thing now. I took her to a derm in a big city and finally he said it's mostly kp mixed with some acne. All over her forehead and cheeks and some on the chin. I am just wondering if anyone else has had a similar experience. I think it is weird that my only 2 children both have the same rare thing in the same spot. Any suggestions?
