I’m 29 and recently gained then lost weight. Is this loose skin or platysmal bands under my chin? (Photo)

Getting Facetite RF and Morpheus8 done under local would make a huge improvement in the neck creases and is easy to undergo.

this is loose skin and bands, you will need a combination approach. botox, morpheus, threads, ultherapy, thermage can be used in the office. facetite can also be used (see link).

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.

At your age, an incisional neck lift for the platysma bands and skin tightening is overkill, and you would want to avoid incisions. Liposuction of the neck would only increase the skin laxity you experienced from your weight loss, Fortunately, you can tighten the skin, lyse the bands, and lift the neck through needle hole incisions with FaceTite and an advanced form of myellevate called a trampoline platysmaplasty
