Can botox be injected just under the arch of the brow and what is the result. Can this cause an eyelid drop?

Botox can be injected just under the lateral aspect of the eyebrow to achieve a brow lift. This works best when the glabella is injected at the same time. If Botox is injected under the mid brow (not laterally) eyelid drooping can occur. I would recommend consultation with a board certified dermatologist or plastic surgeon experienced in Botox injections. Best wishes.

What are you trying to achieve with Botox injections under the brow? If you are looking to get a brow lift then injection of the outer brow and glabella can help provide a lift. Injecting under the brow anywhere other than the outer brow, or injection by an inexperienced provider can result in an eyelid droop. There are other non-surgical treatments which can help lift the brow when used in combination with Botox. Make sure you see an experienced provider.

This may be not such a great idea and could lead to a droopy eyelid. An experienced injector will guide you to a good outcome in case your looking for a browlift. Warmest regards, Dr. ALDO
