Can wrinkles around the eyes be solved with Botox?

I'm considering getting Botox for my crow's feet because of the deep wrinkles that appear around my eyes when I smile or make facial expressions. This is particularly stressful because the wrinkles around my eyes are more prominent in photos, making me look tired. Since the skin around my eyes is thin, I'm concerned that Botox might make my facial expressions look unnatural or make my smile disappear. I'm also curious whether Botox completely removes wrinkles or just naturally smooths them out. I'd also like to know if there's any bruising, swelling, or disruption to daily life after the procedure, and how long the effects typically last. Could you please also explain the recommended frequency and precautions for repeated Botox treatments?
