Does botulinum toxin change a double eyelid line?
Injections near the brow or crow's feet can subtly shift brow height and lid show, though a settled crease itself is not undone.
Botulinum toxin relaxes targeted muscles, and several of those muscles sit close to the eye. That proximity is why a wrinkle treatment can nudge how a double eyelid reads.
Muscle balance moves the frame, not the fold
Weakening the frown or forehead muscles changes the tug-of-war that sets brow position: a lifted brow exposes more lid and can make a crease look wider, while an over-relaxed forehead can let the brow drop and narrow it. Rarely, migrating toxin causes temporary lid droop that resolves as the effect wears off.
Dosing and spread differ with individual anatomy, so results around the eyes are not uniform. Tell the injecting physician about your eyelid surgery history and consult on placement — small adjustments in injection points protect the look you already have.
