Beauty Routine for Teenage Girl?

What should be a typical beauty routine for a teenage girl?

I feel totally lost when it comes to beauty routines. It seems like other girls have complicated skin care techniques etc. My friend dips her hands in all these solutions to make them smooth, and uses multiple products on her face. I don't do anything to my skin–I just wash it with bar soap in the shower! I was never taught to do more than this and my mom doesn't do more either.

I want to have a typical beauty routine, but I don't know where to start!! Should I be having complicated manicure/pedicure/skin/makeup routines? Is it strange not to? I just am so lost when it comes to this and I feel gross for not doing more.

Help me out?
