I'm debating whether to get an anti-aging treatment.

In the past, my skin would recover just by getting enough sleep, but lately, the pillow marks take a while to disappear in the morning, and I can see my jawline sagging subtly. It stresses me out every time I look in the mirror, so I am considering anti-aging treatments.
I visited a few dermatology clinics to look into anti-aging treatments, and they told me that the 'Ulthermage' combination—lifting with Ulthera and restoring elasticity with Thermage—is the best for concerns like mine. However, the cost is quite steep, and I'm scared of potential side effects like hollowing out my cheeks.
For those of you who have received anti-aging treatments, I'm curious if they are really effective and when is the right time to get them! Please give me some honest advice!
