I had Botox on chin. Now I have a weird bump when I frown. Any suggestions? (photos)

This chin just needs more botox injected as some of the muscle is compensating for the areas that were injected.  I would wait 5-7 more days and if this still exists then see your injector for an assessment.  Best, Dr. Emer.

I would strongly recommend following up with the person who did your injections so as to explore your options further.  It may simply be that touching up your injections will provide you the outcome you need.

The quality of the photo does not make me confident in the reason for the bump, and I am unable to compare it to your "before" picture. It is possible this is a deep bruise, an infection, or a partial response to the Botox, causing compensatory strengthening of the untreated area. This would result in the muscle perhaps balling up. I do not think it is serious, but this is not an optimal outcome and it needs to be fixed.

It's very helpful to actually watch you make frowning movements to be able to assess exactly what is happening. In the few cases that I have seen this the effect has resolved with targeted injections of a very small amount of additional Botox. Make sure that you're being cared for by an experienced plastic surgeon or dermatologist injector. You deserve that level of expertise. I hope this information is helpful for you.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Thanks for your question. There are a few possibilities but it could be due to only partial paralyzing of the mentalis muscle or over paralyzing the muscle. How many units were used and how many injection points were used? Was this an experienced injector? This is an advanced technique so be sure to get an experienced dermatologist or plastic surgeon consultation for recommendations and treatment options.

It's hard to tell 100% from the photos but you appear to have some "recruitment," which is a term used to describe when some muscles or portions of muscle compensate (are flexed tighter) for muscles that are weakened by Botox and other neuro-modulators, such as Xeomin and Dysport.The treatment for this normally is to inject a little more Botox into any of the lumps that appear with animation; this should help soften those areas.  There is, of course, a limit to how much you want movement (animation) to be restricted but that would typically be the next step.I hope that this helps and good luck,Dr. Alan EnglerMember of #RealSelf100@RealSelf

From your photos, you may have had a small bruise or hematoma from the injection site.  This may well resolve in a week or so.  Let your doctor know about this, they may want to see you back sooner.  I would avoid heavy lifting or straining until your doctor has had a chance to see you.  Best wishes, Dr. Lepore.

See the MD that injected your Botox and discuss your concerns.  As another week passes this should resolve.  My Best,  Dr C
