f(x)'s Luna appeared on 'Cultwo Show' on June 9 and gave beauty tips.

She first relayed, "Hosting a beauty show is harder than I thought it'd be.  I have to keep up to date on cosmetic research, and it's hard.  I did always like doing my own makeup [though]."

When asked how she maintains her skin, Luna said, "If I don't have a schedule, I go to bed early and wake up early.  Because I live with my grandmother, my eyes open when it becomes 6 AM."
