What is the best cosmetic solution for lower cheek 'bump's to create an even and defined side/lower face? (Photos)

 Hi, I have performed many facial shaping procedures using dermal fillers, silastic facial implants (cheek implants, chin implants, lip implants), liposuction and/or facelifts for over 30 years.  From the photos, your chin is very weak. 
 I have performed many Chin Augmentations using chin implants for over 30 years.  A weak chin creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin and "pseudo-jowls" (the "bumps" hat you are referring to in your post).   Pseudo jowls differ from "jowls" in what causes them, what they represent and how they are best treated.  Pseudo jowls are defined by a fold of tissue laxity that goes from the corners of the mouth to approximately 1/3 or 1/2 the distance to the lower jaw line.  It’s caused by a weak chin and its lack of tissue support around the chin and mouth area.  It's best treated by correcting of the weak chin with a silastic chin implant.  You do not have "jowls", nor would they be expected in a young face such as yours but they are best treated with a SMAS facelift.  
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery.  The cobblestone (bumpy surface) over the chin is the result of an over active Mentalis muscle that is best treated with injections of Botox or a similar neuromodulator to selectively weaken the muscle.
Hope this helps.
