-Simply pour the green tea and apple cider vinegar into a glass jar or a glass spray bottle. -Use a cotton ball to apply your homemade toner after cleansing or as often as desired. I recommend using it each morning and night. -Apply your moisturizer as usual. -Store this toner in the refrigerator, where it will keep for about two weeks. Notes: While the two ingredients alone are enough to make a spectacular homemade toner, you can also experiment with adding 2-3 drops of my favorite essential oils. Try these to enhance the potency of your toner for oily skin: -Orange essential oil (cleanses and tightens the skin, balances oil production). -Lavender essential oil (incredible at soothing and calming the skin). -Lemon essential oil (brightening and toning).
