I'm in my late 30s. Is it too late to start anti-aging treatments now?

Every time I look in the mirror, I sigh at how my elasticity is no longer what it used to be. I didn't notice it when I was in my 20s, but now I can see that my nasolabial folds are deepening and my jawline is collapsing. anti-aging treatments I keep getting more and more interested in it. My friends around me were already getting regular treatments, saying things like "Ulleung Thermageni" and "Ulleung Thermageni", but I guess I was the only one who just let it go. ㅠㅠ

Even now anti-aging treatments If I get it, will my face return to its plump state? There are so many types, which one is better? anti-aging treatments I'm not sure if this will work for me, I'm worried about side effects, so I hesitate to make a hospital appointment.

Is there an introductory course that you would recommend to someone who is trying it for the first time? anti-aging treatments Is there any? It is not too painful and you can definitely see the effect. anti-aging treatments I would really appreciate it if you could share the information!
