I'm really worried about my nasolabial folds and facial elasticity. Please recommend a procedure.

Lately, my nasolabial folds and facial elasticity have really deteriorated. That is why I am looking into InMode, which is famous for firming. I am researching InMode for elasticity management, and I am wondering when would be the best time to schedule the treatment. Since this is my first time trying InMode, I would also like to know if there is anything I need to prepare. It would be helpful if you could also let me know about any behaviors to avoid or care methods to follow before and after the procedure. My skin tends to be sensitive, so I am curious how long swelling or redness lasts. I am also wondering if the effects appear naturally or if a single session is effective, and I would like to hear opinions from those who have actually received the treatment regarding whether multiple sessions are necessary for high satisfaction.
