I finally bit the bullet and got 600 shots of Thermage FLX! Is my skin elasticity worry over?

As I get older, I see my facial skin sagging every time I look in the mirror, so I finally booked and went for a Thermage treatment at a dermatology clinic, which is known as the ultimate lifting procedure. I hesitated a million times because the cost is exorbitant, but I went ahead with it trusting the doctor who verified the genuine tips and administered the shots meticulously. It was definitely a dermatology treatment that was worth the money. I felt a hot and tingling sensation during the procedure, but I endured it with the sole determination to become more beautiful. Now, a week later, I can feel my skin becoming firmer. Since it is usually recommended to get treatments every 6 months to a year, I actually think it is a cost-effective treatment considering how long the results last. I heard that proper regenerative care is necessary to make the effects last longer, so these days I am applying sunscreen much more thoroughly than usual whenever I go out. Are there any other people who have received Thermage treatment who know any great tips for aftercare? Perhaps because it is a radiofrequency treatment, my skin feels a bit dry; please share any hydration tips you have!
