Is it better to get a lifting procedure before it's too late?

I've been looking into lifting procedures lately, and people around me say it's best to start taking care of it before it sags more.

However, I am hesitant because if I start too early, I feel like I’ll have to keep it going. I don't want a drastic change; I just want to look a little less tired. There are so many types of lifting procedures that it’s hard to decide which one to choose. For those of you who have had it done, what criteria did you use when you first started?
