Does Botox start to loosen slightly after a few weeks?

Hello and thank you for your question.  Yes, for some, Botox does tend to feel stronger/tighter at around the 7 day mark but then lets up a bit after a few weeks.  In general, Botox lasts about 3 months with results gradually fading over the last few weeks.  Best of luck.

Hi Lauren. It's not abundantly clear what it means for Botox to "loosen" after injection.  Once Botox takes full effect, the feeling associated with that full effect tends to remain very consistent for weeks afterward.  When the Botox starts to wear off (8-16 weeks), normally patients will describe a loosening feeling because the muscles start to wake up. 

Botox is in full effect at two weeks from injection date and then the effects gradually fade over a 3-4 month period.  Some patients who claim to feel the "tightness" at the beginning state it starts to resolve after a few weeks.
