After giving birth an aquantance now has permanent goosebumps. She is from Nepal (near India), and lives in Oregon. After only about two days in the summer wearing short sleaves, the sun
in the pore. So far the genetic basis of keratosis pilaris has been proven. I suggest your girlfriend to get this possibility evaluated from a dermatologist.
I hope it helps. Take care and please do keep us posted on how you are doing. Kind regards.
