Area where botox injected is white, is this normal?

Sometimes a headache can develop after a BOTOX injection.  If that is the case, unfortunately all you can do is wait it out.  Treat your headache with the meds that you normally use when you get a headache.  Advil is OK if that works for you

Botox should be safe in your case, but you should ask the doctor that will be performing the treatment. Also, you need to get your blood pressure under control as this will potentially have serious consequences down the road. Take care, Dr. Groff

Botox will help soften lines on the forehead, depending on how strong your muscle movement will determine how many units you would benefit from. If your wrinkles are very deep to start, it may require a few rounds of Botox to smooth out the lines, up to 2 yrs of regular injections.

Its best you schedule an in-person consult to be fully evaluated, there are many options to correct or minimize under eye bags like Botox, fillers or blepharoplasty 

A mole on the upper lip would have no effect from having a filler, I suggest trying Belotero, this would give you the most natural result
