How do I treat Platysmal Bands when I'm too young for a neck lift and don't want to keep shelling out money for Botox? (Photo)

Botox is still your best option in your non-surgical options. With continuous use of Botox, it may induce muscle atrophy so that you won't need as much with repeated treatments.

There
are not too many great options for neck tightening, besides surgery and
plastysmaplasty IF someone is a candidate (older age).  However, there are some good noninvasive options. Botox works to tighten the
muscles of the neck and jawline; fillers into the lateral neck and skin
folds work great to fill out lines and give lift; radiofrequency
treatments like sublative/viva, laser treatments fraxel/clear and
brilliant/co2 help texture and tone as well as give lift; ultrasound
(ultherapy) and deep radiofrequency (thermage, velashape, venus legacy) can help
give tightening and lift as well but often require more than one
treatment and are best combined with the other mentioned treatments and
by doing the full face rather than just the neck. I suggest seeing a
cosmetic dermatologist or plastic surgeon who specializes in noninvasive
options and thinks outside the box. Best, Dr. Emer.

The neck bands are caused by flexing of the platysma muscle.  The best thing is to try and lengthen the muscle.  Facial yoga exercises, which can be found on the internet, can be very helpful in improving them.
