Thanks for your question – injecting a small amount of Botox at the tails of the eyebrows can give, when done by expert injectors, a wonderful contour to the eyebrows themselves. We have been doing this to make this natural shape for many years and we do hope that you have these injections performed in the offices of a board certified dermatologist or plastic surgeon who understand the anatomy of the areas the best and who best can guide you on what to expect when different areas of the face are injected.
Botox should never be placed under the eyebrow as you will definitely get Ptosis. Botox lateral to the eyebrows will produce a lift and arch. see a board certified dermatologist or plastic surgeon
