Should I consider a chin implant or genioplasty? I am looking to balance my profile.

You do appear to be a good candidate for chin augmentation. A chin implant is the much less invasive option of the two you listed. This surgery can be performed using local anesthesia and an incision inside the mouth in most cases, to eliminate visible scarring afterward. Sliding genioplasty would be preferred if your teeth are also severely out of alignment. If that is not the case, it is likely you will get a satisfying result from a chin implant alone. I encourage you to schedule an in-person assessment with an experienced, board-certified facial plastic surgeon for further evaluation and treatment recommendations. 

Either one of the surgeries (chin implant, genioplasty) carries risks. The least aggressive surgery of the two is the chin implant.  Genioplasty is a very aggressive surgery and will have more significant risks compared to a chin implant.  With any surgery, risk of infection exists, but is quite low with the implant.  The recovery after an implant is also less painful with less swelling.
A chin implant will only improve your cosmetic appearance. If you think you have a weak chin that detracts from your appearance, make sure you consult with a board certified plastic surgeon for an in office exam to discuss your options.

Based on these photos, I think that both chin implant and sliding genioplasty would give you satisfactory result in good hands. In person consultation with a board certified plastic surgeon, expert in chin augmentation, would help. Good luck.

Dear lemoncakes6,
It is hard to tell for sure without an examination. Based on your photos, it looks like you would benefit from chin augmentation. If you are considering a treatment, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

  A sliding genioplasty is performed by an oral surgeon in a hospital setting under general anesthesia with an overnight stay at the hospital since it is quite invasive.    It is usually performed when the patient's teeth  are significantly out  of alignment.  Placement of a chin implant can be performed under local anesthesia  which takes approximately 30 minutes and is much less invasive.  

Both an implant and moving the chin bone are valid methods of chin augmentation, ecch with their own advantages and disadvantages. It would be important first to look at what dimensional changes are needed for your chin augmentation by computer imaging. Once the dimensions are known then you can see which of then chin procedures can accomplish it best.
