Part 02: The Many Advantages (and a Few Challenges) in Making Mineral Cosmetics
As consumers, we are becoming more alert to the ingredients that we put into and onto our bodies. Commercial cosmetics frequently contain a high ratio of chemically derived ingredients, and all too often, commercial cosmetics contain harsh preservatives.
The most significant challenge in formulating your own cosmetics involves the limited shelf life of handcrafted cosmetics. Unless you add a preservative, your cosmetics will not have the same shelf life as their commercial counterparts. Most of us tend to keep and use our cosmetics until they run out instead of properly disposing of them after a few months. Even heavily preserved commercial cosmetics can become breeding grounds for bacteria because the cosmetics come into contact with our skin. Eye shadow and blusher brushes touch the powders, then gloss over our skin and carry bacteria and oils back to the powdered cosmetic the next time the brush contacts the powders. Mascara brushes touch our lashes and then go directly back into their tubes carrying the oils and bacteria from our lashes directly into the liquid mascara. When you create your own cosmetics, the shelf life is much more limited, but you can keep track of the date that you made them. Because they're less expensive to make, you can replenish your personal cosmetic apothecary with fresh new cosmetics. For more information, see the Shelf Life section of this guide.
