Wait another week or so
Occasionally, Botox takes longer than 10 days to work. I know this from personal experience. Coming back from vacation last summer, I found some Botox that was three weeks old. Not wanting to inject this into a patient (not that there was danger, just a fear of low potency), I had a friend inject it into me ( a dermatologist friend, not my squash playing friend). After ten days it had done nothing. It took a fortnight, but one morning I looked in the mirror and my wrinkles had vanished.
