Want to start taking care of my skin, but don't know where to start?

I never really bothered to do anything with my skin… or cosmetics.

The only makeup I've ever put on to go outside is eyeliner occasionally and gloss (rarely).

But I want to start taking care of my skin. Not makeup so much, but…. cleaning… it…. and…. exfoli-….. that big word that I don't know how to spell.

What are the "basics" ?
