What to do first, Ultherapy or PRP & Threading?

for tightening my patients do threads once a year, thermage and ultherapy once a year, and morpheus every 2-3 months.  prp/microneedling will not tighten your skin it will improve your texture and should be combined with lasers.  Id suggest at home peels like cosmelan and enlighten and to start pressed contour serum (see link).As we age the skin sags there is  nothing  you can do that but try preventative  energy-based or thread-based  treatments or get a neck/facelift earlier in the aging process.  There are numerous options and some can be used in combination to get best outcomes but you need a consultation with an expert.
Options include for skin tightening :

thermage radiofrequency to heat skin and tighten it over time and prevent the aging process
ultherapy highintensity ultrasound to contract muscle and tighten the face and neck and prevent the aging process
PDO nova threads or instalift threads for immediate lifting without surgery and long term collagen production
sculptra injections for collagen production to areas of the face and neck with crepe skin or early sagging
btl exilis ultra, venus legacy, thermi250 , or inmode forma/contoura  for constant collagen stimulation monthly with facials
facelift/necklift with fat grafting/fillers if you need a big improvement
ThermiRF or J plasma /Renuvion or Inmode FaceTite   internal heating and tightening to long term internal heating and tighting with or without surgery
Platysmaplasty to tighten the muscles of the neck long term and create contour
Facial implants or fillers to contour the jawline and chin to improve the apperance of the nec k
Fractora/Morphenus8 or Intensif microneedling RF for improve superficial tightening, neck and chest wrinkling and crepe skin 

You need to see an expert in facial sculpting and age prevention.  Best, Dr. Emer.

Dear Maria, Thank you for your inquiry. An in person consultation is always required when considering Ultherapy treatment. Generally, a combination approach of Ultherapy treatment followed by PDO threads and PRP Microneedling will definitely help you tighten, lift and improve the texture of your skin resulting a complete preventative anti aging treatment. Hope this is helpful. Best of luck !
