Can Botox give the illusion of "bigger" eyes?

Thanks for asking. There are options to "open up" the eyes. See a bars certified plastic surgeon or dermatologist who can show you examples of a chemical (non-surgical) lift. Best wishes

When Botox is injected just below the eyebrows, it can cause the brows to raise up a small amount.  This may give the illusion of the eyes being a bit more open.
