Are skincare routines worth it?

Skincare is one of those things I always feel like I should be better at (and that I'm failing as a girl because of it somehow). I'm lucky as my skin is fine really (I drink a lot of water) so I've never really done anything. Selfcare is something I struggle with generally so never found it worth the effort.

I'm thinking as I enter my thirties though I should. Just had a sheetmask and enjoyed it but I have no idea where to start generally in terms of it.

What's your skincare routine? Is it worth the effort/cost?
