Oh! Traveling Lady, I made using a magnifying mirror a must after age forty...a while ago! It helps me be sure not to over apply make up, which is aging.
Accepting our aging selves is a process. I see I've changed but have accepted these changes as part of what we all go through. I did that by searching pictures of women who are over 50 and looking closely at the ones who look great, pulled together, happy. Then I try to copy what works for me.

We tend to focus on our flaws but I am pretty sure no one else does, or is as hard on us as we are on ourselves.

If your chin/jaw line is the problem, focus your attention on making your eyes/hair beautiful. You can add contour & shadow with make up if you are skilled with a makeup brush. This usually involves 2 or 3 shades of foundation. Whatever you wear, make sure you feel great in it. It helps lift everything about you to others. If you feel great, that is what people notice. How you carry yourself is everything IMHO.

And smile! That focuses the attention to your happy face, not your flaws.
Gravity and skin elasticity are the enemy in my world, and the two things that are impossible to combat. But we can have our teeth whitened to have a great smile.

You are lucky you have a man who still sees you as beautiful. My H picked me apart when I was young and beautiful so now his marching orders are to Zip It. I couldn't bear to hear what he thinks of my aging self. And I console myself that no matter how old I get, he will always be older & saggier ...
