So you've recently ordered some natural skin care products - maybe it's not Eco-Logic ... that's ok, I won't hold it against you ;-) It is said that the very best products to put on your skin should contain ingredients you could possible put in your mouth (I'm not at all advocating you eat ANY natural skin care products). This means, ingredients such as olive oil, avocado oil, coconut oils are fabulous ingredients to cook with, AND to put on your skin.
BUT ... you do have to store your products carefully, just as you would your oils from the store - particularly during the hot summer months or if you live in a consistently hot climate. REAL natural products (not the ones labeled as such with mostly synthetic ingredients) need to be treated as you might treat your groceries. When you go to the grocery store and purchase a large order during the summer - most likely, you'll want to run home quickly and put them in the refrigerator or in your cooler home. Think about the olive oil you purchase in the baking isle at the store - it needs to be kept (ideally) in a dark, cool cabinet.
If your skin care products are genuinely natural, most likely they will contain oils you can find on your grocer's shelves - olive, grape seed, safflower, soybean coconut, etc. This means in order to keep them from becoming rancid (spoiling - otherwise known as the oxidation and degradation of vitamins within the oils) they need to be kept in a cool, and relatively dark environment. Most natural formulators will include oils containing loads of antioxidants such as natural Vitamin E, or Rosemary Oil Extract to help protect the natural oils from early oxidation. However, this is not a 'fool-proof' system. The user has to also take special care to ensure the quality and life span of their natural products.
