My temporalis muscle makes my head bulge out over the ears, can Botox make it smaller? (photos)

Yes, Botox injected into the temporalis muscles between your eye and hairline should decrease the size by a few mm so that your head shape is less concave and more straight. About 20 units per side should help.

Hi, when you smile, the temporarily does appear to contract creating a bit of a convex shape.  It's really not that noticeable and more so because the hair is so short on that area.  In theory Botox (Xeomin or Dysport), should be able to reduce the Temporals size as it does for the Masseter muscle.Hope this helps.
