I don't think vanity is an issue. If changing your appearance by subtly reducing fullness, sagging skin, and deep folds would make you feel more confident and "easy in your skin", then it might be the right thing for you.
I think of vanity as an unhealthy obsession with appearance, but wanting to look attractive is a healthy and natural human motive that contributes to overall well-being. Age is not the issue as long as you are in good health.
Hello, it's never too late to look your best. Based on your photos--- and provided your health is good--- you are a candidate for a facelift. To be more accurate I would like to see your profile photo of your neck down to your collar bones. That should give me a more accurate assessment of your condition.
