I love some of these ideas, and to add my twopenneth:
LED face mask - I swear by mine, and it's become a daily part of my 'get home and unwind' schedule. As soon as I get home, I get changed into comfy clothes, take my make up off, have a 10 min decompress on the bed with my mask, pop up on my evening skincare and then I'm ready to relax.
Depending on your age and your skin, I can definitely recommend Profhilo which isn't a filler, but it injects hyaluronic acid deep into the skin. I've had it a couple of times and while it was pricey (and I found it quite painful), the results were amazing.
Skintags/moles - if you have some that bother you, I paid to have a couple removed and feel 1000 times better and more confident.
I don't wear a huge amount of make up but I swear by Charlotte Tilbury Flawless Filter as a must every single day - I feel dull without it.
As for other things - I now look for ways to elevate my every day. I prioritise quality beautiful things over things I might want in the moment so I buy items less often, but have things that will last and make me happy. I don't save beautiful perfume or jewellery for best, but wear and enjoy them every day. For work, I treated myself a while ago to a lovely work bag and a beautiful notebook which I write in with a very fancy pen with coloured ink, and these things make mundane tasks feel more glam, which makes me happy!
Oh, and have plenty of things to look forward to, even if it's just a coffee with a friend or a night at home with a meal and a movie. That's a must!
