An interesting crease commonly forms above the outer eyebrow in patients that undergo Botox treatment of their forehead. This is because the botox cannot be injected too far down on the forehead as it would make the eyebrow sag and women would lose the arch of their eyebrow, and this also commonly would lower their upper eyelid as the eyebrow supports the upper eyelid. This horizontal supra eyebrow crease can be improved in some patients rather significantly with the use of a hyaluronic acid, Belotero.
