Small double chin, no jawline. Is lipo the only way? (photos)

Hi, thank you for sharing your question. Based on the photos, you would be a better candidate for non-invasive skin tightening rather than liposuction. Morpheus is a good option.

You would probably get good benefit from nonsurgical micro-needling with radiofrequency. for a more aggressive treatment, liposuction with ThermiTight or Renuvion can be done. However, I think the first would do well for you.

Liposuction is not your only option. Amongst patients of mine that have minimal submental fullness, and are not open to liposuction, I sometimes consider 1-2 kybella treatments, to target the bothersome pocket of fat under the chin.
To augment your natural features, I often opt to use dermal fillers to define the jawline and accentuate the chin. I typically start with a shorter lasting filler, and once we have achieved desired results, consider moving towards longer lasting options. These treatment options are ones I recommend even for patients who opt for Liposuction as liposuction cannot add volume to the chin.
To address jowling, I typically recommend subdermal skin tightening modalities such as AccuTite. For patients who do not want to intervene surgically (via liposuction and subdermal skin tightening), I recommend a combination of dermal fillers as well as a series of Morpheus8 RF micro-needling treatments to try and tighten the skin.
While there are non-surgical options to address your concerns, it is important to note that the most impressive results are typically seen with surgical intervention.
