Aiyo, you lazy girl har.
you must use facial wash to wash you face one.
Twice a day. It's a must. then must follow by toner and moisturizer
or night cream.
You are still young so you won't see much problems on your
skin.
But at your age now and you're still not taking care of your skin,
your skin will turn very chiak lat when you are 20+. Believe
me.
You might also want to put make up rite? So you must take care of
your skin.
