A couple months ago I answered a question regarding the shelf life of different types of makeup (read it here). One way to increase the shelf life of your products is to keep your makeup and brushes clean and sanitary. This will also help prevent breakouts and possible infections. Sanitizing your products is quick and easy, and I recommend doing it at least once or twice a month. All you need is some Isopropyl alcohol, a small spray bottle, paper towel, and a little soap and water.
Before you get started, make sure your work surface is clean. You'll also want to choose a work surface that won't be damaged by the alcohol (i.e. don't do this on wood or a painted surface). Next, lay out everything you want to sanitize so you can work quickly and easily.
|These are the types of items you will want to/can sanitize: brushes, powder, blush, eyeshadow, lip sticks, lip balms, tube lip glosses, pencils, eyelash curlers, etc.|
When spraying your products with alcohol, start with the outside container, then open them up and spray the entire inner surface (including lids, mirrors, etc). I usually spray the product itself a couple times, which will completely cover the top layer of the product in alcohol. Once you have sprayed all your products and tools with alcohol, let them air dry, which will only take a few minutes. Using a sanitizing product with a high alcohol content (such as Isopropyl alcohol) will ensure none of your products are damaged or altered in any way due to the fast drying/evaporation time.
Keep in mind, some products cannot be sanitized, in which case, you should not keep them longer than the recommend shelf life. Such items include loose powders, mascaras, liquid eye liners, and any product that you reinsert the applicator after use.
