Weight loss, cosmetic dental work and a fresh modern haircut and surprisingly, less make up. I look more current and fresh with less but more strategically applied make up... loads of useful videos on YouTube.
I used to go heavy on the black eyeliner on top and bottom lines, lived in baggy clothes which are no good if you are a very curvy hourglass as the waist is lost and had 4 inches of split ends (joys of long term depression). I don't have many greys yet but I ditched the harsh jet black dyes (goth at heart) to dark brown. More natural look suits me better and less aging.
Always take Spatone, multi vitamin, D3 and K2, calcium, hair skin and nail and then sometimes milk thistle, turmeric, magnesium depending on how I'm feeling. Diet is keto and I work out at home. I swear the days I use guasha and that Y shaped face roller from body shop my face looks a lot more sculpted and skin tighter.
You have to be honest with yourself and look at what you need to do, somethings are free just need commitment and a routine somethings need money but don't be discouraged if it seems expensive, even starting a small savings pot helps you feel you are getting some way towards it.
Lastly, I try and not compare myself. I used to feel envious when I saw a woman with a better body. It doesn't register as much now because I'm more focused on myself. It's the only body I will ever have, might as well make the most of it and enjoy it.... and everyone has their own insecurities and worries nobody is perfect even if they SEEM so.
