Ulthera Treatment, Recommended Treatment Frequency and Duration

I am looking into Ulthera because of concerns about skin elasticity.

What I am most curious about is how long the effects actually last and the recommended treatment cycle.

It is said that the effects usually last for about 6 months to a year.

Since individual differences exist, I am curious to know how long those who have actually received it were satisfied.

I would also like to know how often hospitals usually recommend repeat procedures, whether it is every few months or years.

Please share any special care routines you paid attention to to maintain the effects for a long time.
