I was also on acne treatment when I was younger. Roaccutane which contains
Isotretinoin she is also on
Isotretinoin, now here is a possible connection. Isotretinoin is also used to treat some cancers. There was a male on this forum who said he developed sticky skin after cancer treatment. Isotretinoin is a retinoid, related to Vitamin A. Overdose of vit A has its own side effects. I am still in extensive research mode, so maybe investigate all this and see if you can relate to anything.
