How can I best reduce the size of my perioral mounds? The part that juts out below each corner of my mouth. (Photo)

Thank you for your question and photograph.  This mound is created by the muscles around your lips that allow for movement.  Unfortunately there is no good way at reducing the size of these mounds, but you may be able to make them less noticeable with dermal fillers applied to the less prominent areas of your chin and jawline around the mounds.   

You may want to consider the use of volume (e.g. dermal fillers or fat grafting) to help smooth the transition between the "perioral mounds" and the depression just underneath it.  I would recommend using a hyaluronic acid based filler to help smooth this transition.

this area is due to loss of volume in the lower chin and loss of projection in the jaw.  Fillers in this area work very well if placed meticulously.  I like using cannulas to limit complications.  Best, Dr. Emer.

The area that you point to has prominence not because of fat. This is a contour situation resulting from the musculoskeletal anatomy. Fillers might be a way of camouflaging the area if you dislike it. Depending on the muscle situation Botox might play a role as well.

My best guess is what you are concerned about is actually due to lack of bony chin projection.My profile photo may be helpful.I don't believe liposuction would be appropriate for your concerns.Your most accurate assessment will come from an in-person consultation with an experienced, board-certified plastic surgeon.Best of luck,Mats Hagstrom, M.D.
