Do your cosmetics have expiration dates? They may not, but that doesn’t mean they’re good indefinitely. Sometimes, you can tell by the texture or consistency that make up may have outlived it’s usefulness. Some products may begin to dry out or separate. With others, it’s more difficult.
However, there are some general rules to keep in mind. First, eye make up, especially eyeliner and mascara, need to be replaced more frequently than many other items. The rule of thumb is to keep them for six months or less. This may be in part due to fluids in the eye mixing with the make up. Bacteria can grow quickly. It’s very important to replace eye make up regularly but especially after any type of eye infection. It is also not advised to add water or other fluids to mascara or liquid eyeliner, as this may increase bacteria.
Lip color, including lip-gloss and lipstick, may last up to a year. Keeping these products longer is not recommended, although many women keep them much longer than that. If you wear one color or brand only on special occasions, the tube may still be quite full, compared to your everday lipstick. If your special one was pricey, you may be tempted to save it. However, did you know that mold and even fungus can grow in make up? Yuck. Most of us would prefer to spend a few extra dollars replacing beauty products than taking chances with any of that.
Eye pencils and lip pencils may last longer than other similar products, but they must be sharpened often to remove the old stuff and expose fresh product.
Cream make up, from foundation and concealer to cream based blush, should not be kept longer than six months. If the consistency changes before then, it’s best replace it.
The good news is that some make up lasts quite a while. Many powder based products will last for about two years. It is important to only use them on clean skin and to clean or replace any applicators regularly.
Be sure to clean containers (or drawers, shelves, make up bags, etc.) where make up is stored as well, as bacteria, mold, etc. can accumulate in residue that’s left behind.
