Toner is a liquid skincare product used after cleansing the face. Its primary purpose is to remove any remaining impurities and balance the skin's pH levels. Toners can also help to hydrate the skin and prepare it for the application of other products, such as serums and moisturizers. There are various types of toners, including those with astringent properties for oily skin and hydrating formulas for dry skin. Some toners contain ingredients like witch hazel or rose water to provide additional benefits, such as soothing irritation or enhancing skin texture.
