Filler vs. Restylane for chin? (photo)

Restylane is a type of hyaluronic acid (HA) filler.  There are several types of Restylane fillers that are used for different parts of the face and have different effects.  They can also be used to blend in the "divots" on the face.  Restylane, or other HA products such as Juvederm, can be effectively used for this purpose.

 Hi, I have performed many facial shaping procedures using dermal fillers, silastic facial implants (cheek, chin, lips), liposuction and/or facelifts for over 30 years.  Dimples or a cobblestone appearance in the mentalis muscle, of the chin, are best treated with Botox or a similar neurotoxin.  If the chin is weak (see below), the chin can be augmented using a dermal filler (typically one of the shaping fillers like Restylane Lyft is preferred) or by using a silastic chin implant.   Any of these options shouldn't create the type of grooves visible in your photo.  These grooves can be softened using precise placement of a thin dermal filler, like Restylane, to fill out the grooves.  Since and "if" these grooves (which is how I read your question) were created by the dermal filler placed into the body of the chin...they are a temporary effect of not feathering in the injected filler.  For that reason, avoiding long lasting fillers like Radiesse or even Sculptra (can last up to 2 years) would seem to make sense.  As the original filler dissolves, the grooves that were created would logically soften and ultimately disappear.  For that reason, having the grooves filled with a long lasting filler may result in an elevated mound as the original filler disappears. You may want to consider Botox to reduce the muscle dimples and a silastic chin implant to correct the weak chin.  This combination would not cause the type of grooves on the sides of the chin.  I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin".  
 Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  
 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 (requires extensive tissue dissection, bone cuts and placement of metal screws and plates to secure the cut segments of bone).  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  
Hope this helps.
