I'm curious if anyone has experienced their lips turning bluish or purple after using DNP. This started happening during my recent cycles with these yellow pills. Even after stopping DNP last winter, my lips remained blue. It began with blisters and then changed color, noticeable to others for almost a year now. I occasionally took Benadryl, so I don't believe it's an allergic reaction. While it doesn't bother me much, I'd like to find a way to get rid of it. Have any of you encountered something similar?
