Cleansing is the basic foundation in a skincare routine. Double cleansing is the proper way to cleanse to have a glowy, dewy skin. It helps remove dirt, debris, makeup, and sebum, setting the foundation for healthy, glowing skin. It is a skin-cleansing method that entails washing twice with two different formulas — one oil-based, and another water-based. 

Oil cleansers help break down and remove excess sebum and oil-based impurities like sunscreens, (waterproof) makeup, and silicones. Oil cleansers come in as oil-based cleanser or a cleansing balm.

Water-based cleansers are gentle sodium laureth sulfate (SLS)-free foaming cleanser that banish any sweat, dirt, debris and other water-based impurities with a that are still hanging around that did not get to be picked up by the oil-cleanser.
