and how long will you see results I'm 52 years old and this will be my first time doing botox
Almis,I would recommend starting with 10 Botox units per side and checking your results after 2 weeks. It is ok to add more Botox after two weeks if needed.
I assume you mean the crow's feet area. Usually I inject between 7.5-10 units per side to get the desired effect.
