Plenty of water, suncream on face even in the winter weather and a good walk daily. Also plenty of sleep, which honestly I find hard to do at the minute with night sweats.
I'm a Nivea fan, have used it since I was a teenager, I've tried more expensive brands and always come back to my old faithful. I use their day& night cream pots for 55+, rich nourishing 48hr body lotion and Q10 energy sheet mask weekly. Definitely doesn't break the bank like some do if you are in a budget.
Enjoy single life, I'm divorced now 11 years and love it. Get out with your girl pals and have a ball, well as best you can at present, but it will come.
