Botox to fix cobblestone chin is now an indented bump. Any suggestions? (photos)

Botox could be used off-lable to treat cobblestone chi on indentations. Botox takes about 3 to 4 days to start acting. Shape and contour abnormalities 1 (one) day after botox application are very likely secondary to swelling and not to the botox effect since Botox's effect is not stablished ( as mentioned above it takes 3 to for days to activate). 

Thank you for your question and photographs and I am sorry that your results have not fully met your expectations.  At only a day after injection your chin will likely have residual swelling and only the beginnings of Botox effects.  Allow your results time to mature over the next two weeks before assessing your long-term outcome. If after two weeks this persists,additional Botox should be able to correct the poor cosmesis.  Hope this helps.
