Are there any side effects from Anti-Wrinkle Injections?
Some bruising or swelling can occur after injections but this is typically minor. It is possible for the injections to reach more muscles than intended and excess activity or alcohol consumption may contribute to this in the first 24 hours after treatment. Rarely this could cause an eyelid to become lazy. Sometimes patients feel that they achieve an overtreated look where the brow is quite immobile.
In these scenarios, the effects are temporary and subsequent treatments can be tailored to suit individual variations. People who have had repeated injections can develop antibodies which stop the toxin from having any effect. Very rarely an allergic reaction could occur.
