Impurities removed by washing:
*Old horny cells
*Sebum
*Sweat, dust, pollen, etc.
Impurities removed by cleansing:
*Makeup
*Sunscreen
*Pore clogging
Impurities that can be removed by double cleansing cannot be removed by washing alone, ie: makeup and sunscreen.
So at the end of the day, reset your skin with "double cleansing" (cleansing + washing)!
