Aktiv komparator: 30-gauge needle
Subjects will be screened, assessed, and randomized to be injected with onabotulinum toxin A using a 30-gauge needle on one side of the face and injected using a 32-gauge needle on the other side during their first clinic visit.
All needles would be luer lock, ½ inch length, and attached to separate 1cc syringes.
Injection depth would be 1-2mm, dermal, and the angle of incidence would be perpendicular.

Tidsramme |
|---|---|---|
|
Visual analog score (VAS) pain rating after each side is injected
Tidsramme: 1 hour on Treatment day
|
Subjects will rate pain using the visual analog score (VAS 1-10) after each side is injected using the 30 or 32 gauge needles.
Lower values represents less pain; higher values represents more pain.
