What is the reason why Thermage is talked about not only for lifting but also for satisfying skin texture?

Besides elasticity, there were quite a few comments saying that the skin looked smooth.

There are also comments saying that they felt the effect of refining their pores and skin texture.
I wondered if there was a difference from simple lifting equipment.

I'm also curious if this is the type where the skin's texture changes over time rather than through immediate changes.
