I got my first treatment of Botox in forehead about a month ago. When flushed I have white spots where I got Botox. (photo)

YES! botox can be used to treat facial redness and flushing.  This is common for my rosacea patients.  I suggest also using a pulsed dye laser or yellow laser to your forehead and botox more "scattered" so it's less noticeable.  Best, Dr. Emer.

Thank you for sharing your question and photograph.  This is not a common manifestation a month after Botox treatment and though it will likely resolve given enough time I would inform your injector about what is taking place.  

Thank you for your question UABelle3. I am sorry to hear about your situation. Botox is a purified protein used to address wrinkles associated with facial expressions. As other doctors mentioned it can also decrease redness and sweating in areas where it is injected. Other treatments for redness include IPL, pulsed dye lasers, and KTP lasers. These devices treat and control redness in the entire area that is treated. Please consult with a doctor for specific recommendations. Good luck!

Botox also decreases sweat and erythema in areas it is injected. It is actually used off label for rosacea and on label for hyperhidrosis. There is no way around this and none of the other neuromodulators are different.
