Ageing doesn't matter a whit, grow older gracefully and embrace the freedom.
It is the person that matters underneath the baggy eyes, the drooping skin and the bits and bobs that just go South inevitably, and the hands, the hands! That's how you know if someone is botoxed up to the hilt ha ha..
If your DH is a lovely person, that is all that matters really. I have saggy skin, I have bags under my eyes, I did manage to keep a decent BMI through genetics because I didn't work on it at all.
People see you for what you are, not if you have a few wrinkles or such. And to be perfectly honest, at a certain age most people will just shrug and say BOTOX if an older person looks great. Not one cares. Well I don't anyway.
There is more going on here than OP is saying I think.
Better to be who you are and not give a fig, than to chase something that will be high maintenance. It will sag eventually. The light shines from within.
