The most common side effects of botox frown-line injection are headache, respiratory infection, flu-like symptoms, droopy eyelids, and nausea. Also, with increased treatment, the skin area may thin permanently. Alcohol consumption may wash toxin from the site of injection and also intensify bruising, thus alcohol intake is not recommended for people with botox injections, which is a downside for those who regularily consume alcohol.
