Time. Good habits. Time to let the good habits show up in your appearance.
I'm nearly 60. About a decade ago I gave up booze (now drinking, carefully and in moderation, again), took up home workouts that encompassed ballet, pilates, yoga. Monitored my calorie intake on My Fitness Pal. Try to stay around 1500 calories, with lots of protein, if I'm going to drink wine, or eat pudding on special occasions, I build that in to my calorie count.
HRT, including testosterone. They will take this from my cold, dead, untroubled by osteoarthritis fingers.
Added weights (about 2 x 12 kgs dumbbells) into my workout routines. Basically, if you want to avoid falls, and be able to push yourself off the ground if you do fall, you need to start pushing weights and build muscle. I currently have an hour weekly with a PT to focus on strength training (for me, core, glutes, hamstrings, dorsal muscles).
Sleep (don't drink, don't have screens in the bedroom, have a good book/sex instead).
Make-up - I need more of it these days, eyebrows, lip liner, mascara, blusher. Never used to bother with this, now it makes a difference.
Nice haircut.
Clothes that make you feel comfortable and confident. If losing a bit of weight helps, do that.
