Detailed answer

Using a cotton pad to apply toner is recommended as it helps to ensure even distribution of the product on the skin. The cotton pad also aids in gentle exfoliation, removing any remaining impurities or dead skin cells. Additionally, using a cotton pad minimizes the risk of transferring dirt or bacteria from your hands to your face. However, if you prefer not to use a cotton pad, you can apply toner with clean hands by gently patting the product onto your skin.
