Is Botox recommended for crow's feet?
Botox is splendid for prevention of crow's feet, and effacement of fine furrows. It's a temporary fix and needs maintenance. Fillers fill in static furrows that are there when you don't smile and work great for 9 months or so. A more permanent measure might include fat grafting, blepharoplasty, or both! Even after, you'd still need maintenance Botox.
Yes, absolutely. However, like filler, Botox is not permanent. Most patients require a repeat dose between 3-4 months. Other neuromodulators like Dysport and Xeomin are also great options in this area.
