Can Botox for migraines reduce crows feet? Yesterday my pain mgt doc gave me botox shots for migraines. This was the 1st time.

This am was chking if minor peeling from a diy 20% salicylic peel 3 days prior was gone. I felt smooth skin where my moderate crows feet were. Looked in mirror & was surprised to see marked reduction. It's hard to believe my 3rd 20% salicylic peel did that. But I thought Botox for migraines could not, it's diff than cosmetic Botox. I got 4 injects - 2 of which were 1 in each temple. Could you please tell me if it's possible the Botox injections could be the reason? Thanks for your time.
