10 Awesome uses for aloe vera - to store your aloe vera gel, keep it in a jar in the fridge. For a longer shelf life you can mix in 500 UI vitamin C powder per one cup of aloe (this can be substituted for citric acid and/or vitamin E if that is what you have on hand). For a smoother consistency and/or to blend in vitamin C, put the aloe gel in your blender or food processor before storing in a jar in your fridge.
