After a Few Days of Botox Injection in the Forehead and Between the Eyes, is It Okay to Squint Heavily?

I agree that squinting after a couple hours of Botox injection is good as it helps the nerve ending absorb the Botox and give better effects. Waiting a week after will not effect the result.

Squinting should not be a problem after treatment. Each injector has different post treatment protocols so ensure that you understand the protocols of your injector.
