Generally, these products are only meant to last a year or two after they’ve been opened. However, contamination can occur at any time, since makeup is always in contact with germ-prone areas like your eyes, mouth, and fingers. A good rule to follow is always discard anything that has changed it’s consistency, color, or smell since you began using it. Otherwise, use these guidelines to assess the shelf life of common beauty products:
- Most powders, concealers and lip balms don't contain water, so they can last longer,
- Cleansers and moisturizers often contain fatty acids, which can turn rancid quickly. Toss after six months.
- Multi-use products such as 3-in-1 sticks and creams can spread germs from lips to eyes and cheeks. Wipe the surface before switching areas, and discard or replace after six months.
- Pencils can last for several years unless you wet the tip with saliva or water. To be safe, sharpen before each use.
- Mascara and eye shadows should be tossed after 3-4 months without fail. The tubes are breeding grounds for bacteria
- Foundations can last up to a year if you keep your fingers away from the bottle. Instead, use a sponge to apply.
- Store cosmetics in a cool, dry place outside the bathroom to extend their shelf life.
*keep an eye on the expiration date of your sunscreens when you purchase them. Discard by the expiration date or after 36 months, whichever comes first.
