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

This does not seem like a good idea since it would cause brow drop. If you wanted some suggestions, posting a picture and asking what is your desired result would help. Botox paralyses muscles. I do not know what if your desired result to advise you alternative treatment or filler. Good luck!

Dear erneern: Botox is an art and a science. The injectible medicine relaxes the muscle fibers to alter the pull of those muscle fibers on attached skin (causing wrinkles), other muscles (causing changes in muscle expression and bone (creating muscle bulges and weakening the joint movement. When injected by a talented and experienced, artful Board Certified Plastic Surgeon and other injectors, wrinkle lines below the brow and changes in the eye “openness” can be achieved. The amount of Botox, dilution, depth of injection and site selection will all determine the result. Botox and all other botulinum products have a variable diffusion so the medication may enter undesired muscle fibers and cause side-effects like: eyelid droop, puffiness of the eyelids with swelling and fat bulging. This is a advanced technique! Pick your injectors wisely. Good Luck!
