90% of skin aging is caused by sun exposure.

Double cleansing means to loosen and lieft dirt, makeup, and sunscreen first (typically with an oil-based cleanser such as BEE-OCH 5-in-1 Skin Whip) and then to cleanse again with a regular water-based cleanser such as soap, cream, or micellar water. Even if you are simply removing makeup as a separate step from cleansing, that’s double cleansing!
