A foaming cleanser is a type of facial wash that produces a rich lather when mixed with water. It is designed to remove dirt, oil, and makeup from the skin's surface, making it a popular choice for daily skincare routines. The foaming action helps to deeply cleanse pores, leaving the skin feeling fresh and rejuvenated. These cleansers are often formulated with various ingredients, such as glycerin for hydration and salicylic acid for acne treatment. They are suitable for different skin types, including oily and combination skin, but may not be ideal for those with dry or sensitive skin, as they can sometimes strip natural oils.
