Ultherapy is a great option for skin tightening and botox for platysmal bands. This will tighten the lax muscle giving the neck a smoother more youthful look. This along with Ulthera which stimulates collagen resulting in a lift and tighter neck will be a great combination of treatments at your age!
Since you are starting to show signs of aging I would recommend skin tightening and lifting procedures such as Ultherapy or Profound RF. Ultherapy is non-invasive and uses ultrasound technology to help build collagen. Profound uses microneedling with radiofrequency and is minimally invasive. You would need to be assessed in person to determine your best option but based on the picture you provided I believe both would achieve your goal to tighten your submental loose skin.
