It’s easy to forget that makeup is a perishable product. While it doesn’t go bad as fast as milk, makeup does degrade over time. These changes can make your eyeshadow palettes and foundation colors look off, as if they have mold or bacteria. You may have heard of the Patrick Ta eyeshadow mold problem. After a lot of research, it was determined that the problem was oxidation, not mold. Here’s what to know to make sure your makeup is safe.
How Does Oxidation Happen?
Makeup oxidation occurs when the makeup is exposed to the air and oils on your fingers. When metal is exposed to air and water, rust occurs. The same thing happens to makeup. Humidity and contaminants in the air cause makeup products to change color and texture. The oils on your fingers can also cause makeup to change its look and feel. Light can even cause makeup to oxidize.
What Does Oxidation Look Like?
Oxidation typically presents itself as a color change. Makeup may appear darker in color. Some foundations oxidize and look more orange as a result. Eyeshadows may break down and appear mottled. This happens when the oils in the formulation separate and rise to the surface. The eyeshadow is safe to use, but it may not apply to your skin as well as it once did.
How Can You Prevent Oxidation?
Preventing oxidation is all about removing the factors that contribute to the phenomenon. First, store makeup in a dry, dark location. The bathroom is a humid setting, which will cause makeup to deteriorate. Don’t store makeup in extreme temperatures, like the truck of your car. Use applicators for makeup, not your fingers. Clean those applicators regularly. Know when you should replace different products. A cream and powder foundation duo may last up to two years, while mascara should be replaced every six months to a year.
How Can You Tell If It’s Safe To Use Your Makeup?
The Patrick Ta mold issue brings up an interesting point. How do you actually know if your makeup is bad or if it’s oxidation? There are some key signs that makeup isn’t usable any longer:
Check the expiration date on the makeup. Makeup that is over its prime should be replaced.
Does the makeup have a bad aroma? A bad odor can mean bacteria has grown in the makeup.
Look for a change in texture or consistency. Older makeup won’t apply as easily as fresher makeup. It may be safe to use older makeup, but you shouldn’t take a chance.
Changes in color can also mean the makeup is old. It can be a sign of mold or bacteria, but it can be oxidation, too. If your makeup is darkening in color, replace it.

Take care of your makeup to make sure that it is in good condition and ready for any occasion. Buy well-formulated makeup products that reduce oxidation. Buy new makeup when products expire. Understand what causes oxidation to prevent it and avoid the inconvenience of makeup products that appear off.
