I have a gaunt look? Can the gaunt look be reversed if i get implants. (photos)

You don't appear gaunt.  You do have some scarring in the cheeks which can cause some depressions and loss of volume.  Release of the scars and some fat injections can help with this.  Non-ablative fractionated resurfacing can also help even with darker skin tones.  You may also want to consider a chin implant to strengthen the jawline.   

A frontal view would have been a useful addition to the two the two side-view photos provided. However, there does seem to be some flattening, or perhaps mild hollowing of the mid cheek regions, which may also be increasing the prominence of your acne scars. Invasive surgery, however, with its expense and attendant risks and complications is not your only option or perhaps not even the best option. The use of an injectable volumizing filler, such as Voluma XC, which I would choose in my Upper East Side Manhattan practice, oe Stylage XXL, which would be my filler of choice in my Israel satellite facility (where a far greater number of regulatory agency approved fillers are available) would be one simple, no-knife approach to treating this problem. The procedure would take approximately five minutes per side to perform in experienced hands, engenders little to no post-treatment downtime, and typically prompts an immediate "Wow!" response. As an added bonus, the mid-facial reflation that would be achieved in this fashion would likely also help to smooth some of the acne scars whose prominence may have been enhanced by the volume depletion in the mid cheeks.You would do well to seek consultation and treatment by a board certified aesthetic physician with expertise and experience in the use of injectable fillers and volumizers for nonsurgical facial enhancement and rejuvenation. Since the male face differs in many ways from that of the female, you must make sure that the physician injector you choose also has experience with treating men in this fashion in order to avoid having your face inadvertently feminized. So, vett your potential physicians carefully.

Hello and thank you for your question. It is difficult to give you a full assessment based on these photographs alone. I recommend that you seek consultation with
a qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

Your face doesn't look too gaunt or thin. For those issues, filler or dat transfer is best. If you are thinking about augmenting your lower facial structure, I can see how that could benefit. A chin implant is a great option. For the angle of the jaw, implants, in my opinion have a lot of issues, most notably asymmetry is a big concern. For that reason, and a few others, I prefer filler for increasing angle definition. 

I would not say that you have a gaunt appearance, but there is some loss of volume in your cheeks that could be improved with either fillers or implants.  There are a variety of implants and fillers that could be used.  I would recommend consulting with a facial plastic surgeon or plastic surgeon to discuss your options.
