Eyelid ptosis: what it is and its relationship with toxin
Eyelid ptosis is the drooping of the upper eyelid, which comes to cover more of the iris than normal. It can affect one side or both, and be mild or severe enough to interfere with vision. It is different from a drooping eyebrow (brow ptosis) and from excess eyelid skin, although all three can occur together.
What are the causes?
Ptosis can be congenital or acquired. Acquired causes include aging (with loosening of the muscle that lifts the eyelid), prolonged contact lens use, trauma, eye surgery and neurological and muscular diseases. Ptosis that appears suddenly, unrelated to a procedure, requires medical assessment.
Why does it matter in facial harmonization?
Eyelid ptosis is a known unwanted effect of botulinum toxin in the glabella area and, less commonly, the forehead. It occurs when the product spreads to the muscle that lifts the eyelid. That is why treatment of the corrugator muscle is planned with attention to individual anatomy. When it happens, it is usually temporary, and the course of action is determined by the qualified professional.
It is also important to record, before the procedure, whether the patient already has ptosis or eyelid asymmetry. Many people compensate for a low eyelid by raising the eyebrow with the frontalis muscle; blocking that compensation can reveal a ptosis that was already there. Standardized photos and the informed consent form help document this point.

Harmy's History keeps the frontal photo of each session, which helps compare the position of the eyelids before and after treatment.
Also called: blepharoptosis, drooping eyelid.
Frequently asked questions
Is ptosis after botulinum toxin permanent?
Generally, no. It is usually temporary and resolves within a few weeks, as the toxin's effect fades. The patient should contact the professional who performed the injection for an assessment.
