In the older affected person, a combination of loose pores and skin and attenuated orbital septum can even more aid the dissection of injected botulinum toxin.

The incidence of blepharoptosis is lowered by administering botulinum toxin injections at the least 1 cm higher than the supraorbital ridge over the midpupillary line when managing the corrugator muscles. It may possibly occur as early as forty eight h or as late as 7–10 times adhering to injection and can persist for two–4 months.
