I need suggestions on how to make my chin smooth(er) when I smile or move my my face. (Photo)

 I think your best option is to try Botox.
There are a few muscles that could be contributing to the skin Lines your face creates while smiling.
These include the mentalis muscle or the depressor anguli Oris muscle.
It may take some experimenting and you should definitely look for a boat that's provider Wesson integral understanding of facial anatomy.
I would not recommend any surgical intervention.
Using fillers for dynamic skin folds is sometimes not all that successful.
What this means is adding fillers to lines that on the form when you contract muscles may have an undesirable affect when those muscles are not contracted or your face is in a neutral relaxed state.

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  From the photos, your chin is very weak and there appears to be both a lack of adequate mentalis muscle volume along with specific areas of muscle hypertrophy creating the dimples and grooves when smiling.  There is some excess skin but very little if any fat...both can be removed at at the same time that the chin implant is placed. A step wise approach to the treatment makes the most sense to me.  First augment the weak chin with a properly placed silastic chin implant as described below.  Then at about 3 months post-op, if the dimples and grooves persist, use Botox or a similar neurotoxin precisely placed to create spot weakening of the mentalis muscle. 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.  In my opinion, you are a good candidate for chin implant surgery.  
Hope this helps.
