I've got deep crow's feet on my forehead. botox did not do much good. any effective way to reduce these lines?

Yes: You are confusing crows fee (lines typically at the corners of the eyes) with forehead wrinkles. If you are speaking about forehead wrinkles, the doctor injects the forehead using approximately 15-20 units of botox. Botox is extraordinarily effective in minimizing forehead wrinkles.

Static lines: Now all wrinkles will disappear after your first botox treatment. Some lines are static and are present even when your muscles are relaxed. If you look before botox im sure when lifting the brows up you had more lines that you likely can not make today ( see if your MD took pre photos) if you continue using botox in time your body will soften up those static lines if not remove them
