The side effects of Botox injections may include:
2) Swelling around the injection site
3) Temporary drooping of the eyelid (ptosis)
A shiny forehead my be a result of the lack of muscle movement in the area. If the muscles in your forehead are not contracting as they would normally, then the area will appear smoother. This smooth appearance can give the illusion of a shinier or greasier forehead. I hope this helps answer your question, and enjoy the result of your Botox treatment!
