You should definitely know something: We have a face for life, but not a handbag! Use SPF every day, even when the sun isn't shining! Micellar water alone is never enough to remove make-up! You don't need smoky eyes when you have a good lipstick. If you watched Beverly Hills 90210, you need to use retinol (if you don't know what BH 90210 is, you don't need to). You're welcome.
