I use Sally Girl Cuticle Oil I got in a swap as an extra, so I don't know what it costs. It's an oil that has a neutral soft smell and it's easy to apply with the brush.
Naked stained nails! I chose the picture that made my nails look less yellow on purpose so it's worse in real life. I still haven't found a base that protects from staining. Here you can see it applied. It takes a little while to absorb but I think that no cuticle oil fully does.
I also use nail care pens and cuticle oil pens but I'll show them later.
What do you use for your cuticles?
