2 days post botox and I have a lump across my chin. Should I let it heal or do I need more botox?

Thank you for the question. There are a coupe of possibilities here. First, Botox takes 3-5 days to exert its effect. So, if you are noticing a bump or a change in the area of injection prior to this time, it is likely related to the injection site rather than the Botox itself. This could be a little bruise, for example. Ice may be helpful and this should resolve in a few days.  If it has been more than 5 days, and you are seeing different lines or muscle activity, it is possible that a touch up would be beneficial. Sometimes making one muscle weak leads to an apparent increase in activity of a neighboring muscle. It's like a "tug of war" situation and can generally be addressed with small additional doses.  Take care.

Areas of irregularity a few days after Botox or are usually related to a small amount of bleeding from the injection (either a bruise or small hematoma).  This will usually resolve within 2 weeks. Call your provider if this does not go away or the area becomes painful.

Initial raised areas after injections are usually at the site of injection.  Botox can take up to one week to begin working.  If the bump is still present at a weeks time post injection you should have the person who injected you assess the area.
