Some people note that their chin is dimpled and active when they speak or are at rest. This may be caused by an active mentalis muscle that can distort the contour of your lower face and cause an uneven appearance around the mouth. 

Recession of the chin can disrupt the balance of the face and can occur in combination with an active mentalis as described above. 

One effective treatment option is wrinkle relaxer injections to relax the mentalis muscle if appropriate. Dermal filler can be used to help project and elongate the chin and enhance the profile to provide better balance.
