If I get Ulthera consistently once a year, will I maintain skin elasticity well?

Entering my 30s, for the purpose of anti-aging and maintaining a lift

I am planning to get Ulthera treatments regularly, once a year.

I am curious whether my facial contours return to their original state after about a year following a single treatment, or if the more consistently I receive treatments, the less my skin density and elasticity decrease, and if they are maintained well.

Is there anyone here who has been receiving Ulthera treatments long-term, at one-year intervals, for 3 to 4 sessions or more?
