Why do we use it in recipes? We use distilled water in our formulations because it removes the variable of whatever might be in tap or mineral water. Learn more here.
Do you need it? Yes
Strengths Inexpensive, easily available, low-variable water.
Weaknesses It doesn’t come out of your tap?
Alternatives & Substitutions De-ionized water is a good alternative, and tap water will likely work in a pinch assuming your tap water is clean and not extremely mineral heavy. You can learn about other alternatives here.

If you’d like to fancy up a recipe you can swap some of the water for other watery-type ingredients like aloe vera juice, witch hazel distillate, or hydrosols.
How to Work with It Use as the recipe directs—it’s an extremely flexible ingredient!
Storage & Shelf Life Stored somewhere cool, dark, and dry, distilled water should last indefinitely.
Tips, Tricks, and Quirks Distilled water is not sterile—it simply lacks the minerals and salts that can be found in tap water or mineral water.
Recommended starter amount 4L (1 gallon)
Where to Buy it  I recommend buying it from your local grocery store; you’ll be buying it roughly 4L/1 gallon at a time (at least) and you don’t want to pay to ship that!
