This refers to the pulled up chin possibly also pock-marked with little dimples and often seen in combination with turned down corners of the mouth that creates a negative, scornful, “doubting Thomas” type appearance.

Skillful Botox administration to the chin can smooth it out also creating a nobler chin profile.  This is also part of the treatment of a chin crease.  Additional treatment for melomental folds is often combined, thereby ameliorating this combination of skeptical negative features. 

Incorrect placement of Botox injections at this site can cause a bizarre lower lip smile so do not choose a beginner or unqualified injector.
