Best option to reduce or remove loose skin under chin? (Photo)

Your question would best be answered by a consultation.  Depending on a number of variables including your age (not mentioned), presence or absence of a strong chin (not seen in profile), a surgical approach and potentially a chin implant may be the best solution.

"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

Coolsculpting
and Kybella are two excellent treatment options for fat reduction as they
specifically treat and damage/destroy the fat cells contributing to submental
fullness.  These treatments are indicated for fat reduction but are not
indicated for skin tightening.  Achieving a sustainable goal weight is
preferred when preparing for a treatment as this helps your provider best
assess and examine you at a baseline.  That being said, it is possible
that weight loss can contribute to skin laxity as fat distribution changes with
volume loss.  Ultherapy and ThermiTight are two non surgical options for
skin tightening.  Surgery is a predicable way to remove excess skin that
contributes to laxity that is outside the treatment parameters for non surgical
options.  Once you reach your goal weight I would recommend a consultation
with a board certified plastic surgeon where your concerns can be reviewed and
you can be examined to determine the best treatment plan for you!
