A cleansing foam is a water-based facial cleanser that removes sweat, dirt, excess oil, and remaining impurities from the skin, leaving it feeling fresh, clean, and revitalized. Known for its rich, airy lather, cleansing foam creates a deep yet comfortable cleanse that helps wash away residue without leaving the skin feeling heavy or unclean. It is an essential step in many Korean skincare routines, helping to maintain a healthy-looking complexion while preparing the skin for the products that follow.

In the Korean double cleansing routine, a cleansing foam is used as the second cleanse after an oil-based cleanser, such as a cleansing balm or cleansing oil. While the first cleanser removes makeup, sunscreen, and oil-based impurities, the cleansing foam eliminates any remaining water-based impurities, sweat, and residue. This two-step cleansing method helps keep pores clear and ensures the skin is thoroughly cleansed without compromising its natural moisture barrier.

Cleansing foams are available in formulas designed for every skin type and concern, from dry and sensitive skin to oily and acne-prone complexions. Many Korean cleansing foams are enriched with hydrating, soothing, and nourishing ingredients such as hyaluronic acid, centella asiatica, green tea, rice extract, or ceramides. These ingredients help support the skin while cleansing, leaving it feeling balanced, comfortable, and refreshed rather than tight or stripped.
