I'm 27 years old, skinny and have a double chin. Thought? (photos)

"For a double chin, InMode FaceTite with VASERlipo would give you the best result.

With significant neck sagging you would need a facelift / neck lift with muscle tightening (platysmaplasty). At the same time, I would recommend lasers (Fraxel, CO2, Halo, or Erbium) and microneedling RF (Fractora, Morpheus8, PiXel8, Intensif) to improve the crepey skin and wrinkles. Overall, the neck can be treated with a combination approach:

1. Microneedling and laser treatments for texture
2. Botox, Dysport, Xeomin or Jeuveau to help platysmal bands
3. Intensif, Fractora, PiXel8, or Morpheus8 microneedling RF for crepey skin and lifting
4. Injectable fillers like Belotero, Restylane Silk, Versa, and Juvederm Volbella to improve lines and folds
5. Face/neck lifting if sagging is prominent or premature, with or without platysmaplasty (muscle tightening)
6. Renuvion (J-Plasma), ThermiRF, and InMode FaceTite/AccuTite for internal tightening
7. Ultherapy and Thermage for external tightening
8. Regular Venus Legacy, Exilis Ultra, or InMode Forma treatments with facials to maintain tightness
9. PDO NovaThreads or Silhouette InstaLift cone threads for lifting and long-term collagen production

Thank you for your question and photos. Unfortunately, it is difficult to make a determination from your pictures alone. If submental fat under the chin is the issue, a treatment like Kybella or liposculpture to remove the fat might be your best bet. However, if skin laxity is more of a problem, a skin tightening treatment like Ultherapy or Thermage might meet your needs better. It is also possible you would benefit from a combination of these treatments. I recommend you schedule an in-person assessment with a board-certified cosmetic dermatologist that can evaluate your specific concerns and create a customized treatment plan that will meet your needs best. Good luck to you!

You are partially correct, in that you are thin, but I would disagree with your assessment of a double chin.  Remember, your neck needs skin to allow your head to move in all directions and what I'm seeing on your photographs appear to be quite normal.  This is based on your photographs and if you want confirmation I would suggest seeing a board certified plastic surgeon experienced with face and neck lift procedures.
