I opted for Botox only in my middle upper forehead. Now I have Hyper-glabellar area. Can this be fixed? (Photos)

I suggest you see your physician this may need touch ups, yes it can be improved by an expert. Best, Dr. Emer.

Dear Ladythebug,Treating the frontalis can be a great idea.  Creating balanced results with a re-freshened and relaxed appearance is easily achievable.  My recommendation would be to defer to the expertise of your surgeon and let them create the result that you want, but with the tools that they need.Be healthy and be well,

This is a predictable outcome when such little Botox is given to an isolated area without taking into account the surrounding musculature. Fortunately, it can be fixed by adding more Botox to the glabella area and rest of the forehead. Be sure all your questions are answered before treatment. Best wishes.
