Toners and clarifiers are designed to be applied to the face just after cleansing and prior to moisturizing, for the purpose of removing any final traces of cleanser residue, excess oil, dirt, dead skin cells and makeup. One look at your cotton ball or pad after using a clarifying toner will reveal its effectiveness--and the reason behind these products' popularity! Some toners and clarifiers are specially formulated for those who wear heavy makeup. Water-resistant and waterproof cosmetics require an oil-based makeup remover, and a good toner is necessary to eliminate any oils these removers may leave behind. Special formulas are also designed for those with oily or acne-prone skin, while milder, irritant-free toners and clarifiers are great for all skin types.
