Can I change my square face or extra skin on my face? Naturally or by surgery?

It is difficult to answer your question without a face-to-face evaluation, or at least, a photograph. However, a "square" face can sometimes be due to excess bulk (hypertrophy) of the jaw muscles (the masseter muscles). This may be just how you developed, or may be due to you grinding your teeth in your sleep, thus working the muscles hard. If this is the reason for your "square" face, then the contour of the jaw can be reduced by injecting Botox into the masseter muscles in your jaw. This is quite a straightforward and routine procedure.

There are ways to slim down the face and/or soften a square appearance of the jawline with or without surgery.  However, it depends on what and where the area of concern is.  Please consult with a board certified specialist who can assist you with achieving the results you seek.  3-dimensional computer imaging can also help assist the consultation process.  However you will need parenteral consent prior to any type of treatment, surgical or not.
