Does anyone get sides off of this. I use XANDROX 15 and i think it has caused my problems for years. I get burning sensation in morning after putting on my hair gel? I was wondering if it causes irritation. I put it on at night, no sides or burning. THen i wake up, i put my hair gel in, and my face gets sort of hot and flushed all day off and on? Could this be a sign of this acid? ALso, my pigment on face just gets red as do my arms? Could this acid get into bloodstream and cause loss of pigment? PLease let me know if any of these sides make sense? I have read about this and seems like some of these sides could be due to using azelaic acid
