I have my eyebrows threaded, otherwise all the small black hairs (which I could see to pluck out), which are now white, cling on to the mineral foundation I use. This is not a good look 
My eyebrows are naturally very dark (not black), but as I race towards 50 I am noticing more and more white hairs growing within my eyebrows. And they are growing longer too.
I also have my eyelashes dyed, as, (again) my eyelashes are losing colour, and as my eyes are dark brown, and the brows are mottled!, I just look odd if I leave them natural.
My skin is the worst it has ever been. I now have acne on my chin, and the occasional spot on my nose or cheek. Also various minor blemishes have started to appear, and a 'dimple' like feature has appeared on my jawline (no idea what this is).
Fortunately I have good genes and oily skin, so at least I'm not too wrinkly (yet).
I try not to get too obsessed about it. If you look at some of the 'celebrities' without their makeup, most of them look nothing special, you could walk past them in the street and not even notice them.
At the end of the day, what matters is how you feel about yourself, both physically and mentally. It actually doesn't matter how you look, it's how you feel about that.
I tend to wear what is comfortable, and I like to think I have developed my own style, which I am happy with. Ideally I would like to lose 3 stone (or so) as well, but I just don't have the willpower or motivation atm. I am currently wearing black jeggings, with black pumps, and a lightweight pink jumper.
There actually aren't that many people who don't have to put more effort in to keep healthy as they age. Find what suits you, and makes you happy.
I sound like a right catch
