Dry skin types -- Warm water can be used to freshen up the skin in the morning. Cold water can actually be used to tighten the pore if you have dry skin some toner can be too harsh and dry the skin out more so you might want to use water instead.
Oily skin types -- Use a small amount of your cleanser. Cleansers that use water and froth up are a better formula for oily skin, insuring it stay oil free for longer!
Combination skin type -- Even though in the video I say cleanser I meant tone, The toner will clear the skin of any excess oil that might have collected over night but unlike using a wash wont be to harsh on the dryer areas of the skin. (warm water can also be used)
