Here’s what you do:
- Mix all of the ingredients in a small bowl until the granules have dissolved. If you decide not to use vitamin E or glycerin, add an extra teaspoon of water so that the serum isn’t too strong.
- Transfer the mixture to your dark glass bottle.
- Use once a day, preferably in the evening after cleansing and toning, and before moisturizing. Allow it to soak in and then apply your moisturizer.
