Really treating myself, I like manicures with paraffin wax. I like spa-y places, where you're not just at a table. There's also facials. The place I go to also has a lip balm that you can only get if you do a facial there.
Milder, I like getting new nail polishes and doing my own nails. I also get the Boscia booties for my feet. Also, I like sports massages, even though I'm kinda embarrassed to see my RMT because I haven't been working out, and they KNOW, so while it can make my body feel better, I'm also not left feeling that great about my body!!! I like bath stuff with some oils in there for my skin in THEORY; I got a bath bomb from Lush that I've used, and I have another one from another place that I'll use soon. But the idea of thoroughly cleaning the tub after is ehhh.
I got some body lotion, but like... idk it feels like I'm buying myself a nicer vacuum cleaner? It seems so practical. I also do Mask Mondays with my friend, so while I like the results, putting on a mask seems kinda routine.
