An essential cleansing foam is a type of facial cleanser that helps to remove dirt, impurities, and excess oil from the skin. It typically comes in a foam or lather formula that is applied to wet skin and massaged in before being rinsed off. Essential cleansing foams are known for being gentle on the skin and effective at removing makeup and other debris from the face. They are often formulated with ingredients like glycerin and hyaluronic acid to provide hydration and prevent the skin from drying out. Some popular brands of essential cleansing foam include Cetaphil, Neutrogena, and La Roche-Posay.
