Can Botox be used to open up the eyes when smiling?

Yes, Botox can be used to create the appearance of wider, more open eyes. This requires small doses placed in very specific locations. I would recommend consulting with a very experienced board certified physician for this treatment. Best wishes.

Yes botox can be used for "eye opening" and shaping.  Its a very delicate procedure, although relatively easy, and I suggest seeking someone with experience.  I think I have a photo uploaded here that shows that botox can do for this problem. Seek an expert.  Best, Dr. Emer.
