One side of my cheek feels tighter than the other. Is this normal?

Thank you for your question. It is normal to experience some tightness up to 14 days after treatment. If you still experience tightness, I recommend contacting your provider. Always make sure you seek treatment from a board-certified dermatologist. 

Xeomin can take up to 10-14 days for the entire effect to be felt.  Some tightness in the treated areas can be very  normal.  Many of us have stronger muscles on one side of our face than on the other, so the weaker side may respond more to the same amount of Xeomin and, therefore, feel tighter.  I recommend following up with your injector in order to see if you need a little more in the side that does not feel as tight (and is probably moving more).  However, if you don't like the tight feeling, don't worry.  It will likely lessen in 2-3 weeks.Best of luck to you.
