Eyelid ptosis vs brow ptosis after toxin — how do you tell them apart and manage?
I get confused between the two. Can someone lay out how to distinguish eyelid droop from brow heaviness after toxin, and what actually helps?

They're different problems with different causes: • BROW ptosis (heaviness): the frontalis has been over-weakened, so the brow sits lower and the upper lid feels hooded. It's a positioning problem. Prevention is assessment and conservative forehead dosing; it settles as the toxin wears off, and sometimes a tiny dose to the lateral brow depressors can lift slightly. • EYELID ptosis (true lid droop): toxin has diffused to the levator palpebrae superioris, so the upper eyelid itself drops. This usually appears within days to ~2 weeks. Apraclonidine 0.5% eye drops (or an equivalent alpha-agonist) can stimulate Müller's muscle and give ~1–2mm of temporary lift while it recovers. Reassure the patient it's temporary (typically weeks). Prevention for lid ptosis: accurate glabellar placement, correct depth/volume, don't over-dilute into large spreads, and keep away from the mid-pupillary line low on the forehead. Always warn about both at consent.

Worth having the apraclonidine route thought through BEFORE it happens — knowing how your patient would access it (via the prescriber) turns a scary call into a calm one.
