Micelles are tiny, hollow molecular balls made up of gentle cleansing oils, which are suspended in a fluid to create a Micellar Water. Because of their chemistry, the micelles act like magnets that attract dirt and other impurities (like makeup particles). The impurities get wrapped inside the hollow micelles, so they are easily swiped or rinsed away. Because they attract dirt, not water, Micelles work without drying out the skin.
