What can be done about my jowls at 21? (Photo)

You don't have jowls yet, but you can achieve some tightening with micro-needling with radiofrequency treatments with no downtime and no risk of making yourself look older than you should with removal of buccal fat.

most of my younger clients use fillers to give them shaping especially on the cheeks, jawline, and chin which make the face look more slim and tight; and threads such as PDO or Instalift can build collagen and support the facial shaping and skin looseness over time, slowing down the aging process and given the face a more “snatched” look; and morpheus deep microneedling RF can tighten crepe skin especially on the neck and jawline and is great for long term tightening of the full face, neck and chest; its often used to give the face a slimmer more sculpted look because it tightens the skin and gives lift.  an early face lift can be performed as well even in younger clients if they want a different facial shape, maxillofacial surgery with bone breaking or shaving can also be done.

For facial slimming a combination of treatments are always needed.  Options include:
1. Buccal fat pad removal to reduce fat on the lower face
2. Factite or Renuvion/J Plasma to tighten the lower face, jawline, and chin to reduce fat and give the jawline and neck tightening and shaping.
3. Botox to the masseter to reduce the muscular size of the jaw giving the face an illusion of being more slender
4. Fillers to the jawline, chin, cheeks, temples and brow help to shape the face and make it more angled and defined

Always use at home derma rolling (see link to Emerageskin x anteageMD roller plus stem cells/hyaluronic acid ampules) and peels like emeragecosmetics enlighten or aerify that can be used to improve skin quality and tighten the skin while improving wrinkles, pigmentation, acne, and Melasma.

 See an expert who does facial shaping with surgical and non surgical methods to get a comprehensive option.  Best, Dr. Emer.

It is difficult to answer your question with a consultation. The face is delicate and requires careful examination. That being said, high definition VASER liposuction is the most efficient liposuction technique for removing fat in small, stubborn areas. The Gold Standard for superior liposuction results requires use of the advanced technology of ultrasound assisted VASER liposuction. As an official trainer of VASER liposuction, I perform full body liposuction cases every week. VASER liposuction has been the only modality that has consistently resulted in outstanding liposuction outcomes. VASER liposuction ensures a smooth contour regardless of degree of excess fat by virtue of being able to remove any and all remaining fat comprehensively and uniformly. If skin redundancy is observed, Renuvion technology can be simultaneously applied to tighten your skin to optimize your overall contour outcome. A Skype or FaceTime consultation with a VASER specialist will help you get an accurate recommendation and pricing.
