Nutrition and exercise really matter at this age
i was getting a bit puffy and chubby and felt past my best in my 40s, really cut back on alcohol, upped the sport, started eating good quality home made food, and now at 51 am in better shape than I was at 40
fresh air important too, I walk the dogs every morning, gives a better complexion
cheap fixes for hair: a cassia (colourless henna) mask every month
a vitamin c serum (makes complexion more even)
spf every day
eat all the good quality food like oily fish, nuts, vegetables, avocado, good quality meat/protein
take vitamin d supplement
keep an eye on your iron levels
do exercise, and have a magnesium supplement before bed (to aid muscle relaxation)
these things work for me
