Can you get chin and lip fillers after having a chin implant?

Yes, you can have filler after an implant. I’d suggest augmenting your chin with Sculptra and/or Voluma. Lip augmentations with fillers is a great option to improve the fullness, suppleness and symmetry of the lips. Results can be very natural-looking and will feel very natural. I prefer to use a micro cannula to inject the lips to prevent bruising. Look for a cosmetic dermatologist or plastic surgeon who is an expert in fillers to discuss your desired results and concerns. 
I hope this helps.

Approximately 30- 45 days following a chin implant, I would be fine with lip augmentation using HA fillers, as well as injecting the mandible adjacent to the silicone implant.  The risk of any infection or abnormalities affecting the chin implant at that time will be negligible and these injections can be performed safely in the office.  Best of luck to you and trust your face to specialist.

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  There's no issue with further augmenting your chin with precise placement of a dermal filler after having a silastic chin implant once the post-op healing phase has been completed. 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.
