1. Toners are crucial to the cleansing process. Toner removes the final residue of make-up, dirt & oil leftover cleanser and unless you are using filtered water to cleanse your skin, there is chlorine, calcium, flouride and other heavy metals in the water that will be left on the skin. When the chemicals dry, they shrink, leaving a white film, and ultimately leaving you feeling tight and dry. If you put a moisturizer directly on top of these chemicals, you will continue to dull and dry the skin. The film must be removed with toner using a cotton pad.
