Botox for a 70-year-old?

Although the company doesn’t have a formal approval for your age, there is no medical reason that you couldn’t have treatment.   Unless it would increase the chance of a droop due to a weak forehead, which in turn could cause lowering of the upper eyelids.

Go for it!  Botox can address your wrinkle concerns as it can for anyone else.  Just be sure to mention to your plastic surgeon if you're taking any sort of blood thinner medications as you may have more bruising if you do.  Otherwise, you should be just fine.

If you do not suffer from a neurological disorder such as myasthenia gravis and do not have any swallowing or speech disorder then you can have Botox done at age 70
