A cleanser is a product designed to remove dirt, oil, makeup, and impurities from the skin. It helps maintain skin health by preventing clogged pores and breakouts. Cleansers come in various forms, including gels, creams, foams, and wipes, catering to different skin types such as oily, dry, or sensitive. Using a cleanser is an essential step in a skincare routine, often followed by other products like toners and moisturizers. Regular cleansing can improve skin texture and appearance, making it look fresh and rejuvenated. Popular brands of cleansers include Cetaphil, Neutrogena, and CeraVe.
