Makeup is a daily essential for millions, yet few consumers fully understand how long their products are actually safe to use. While many items remain in makeup bags for years, cosmetic formulas are not designed to last indefinitely.
Expiration labels, often marked by a small open-jar symbol with a number inside, indicate how many months a product is safe after opening. For example, a “12M” symbol means the product should be used within 12 months once opened. This timeline exists because exposure to air, light, and bacteria gradually breaks down ingredients.
Liquid and cream-based products—such as foundation, concealer, and mascara—tend to expire the fastest. Mascara, in particular, should typically be replaced every three months due to the risk of bacterial contamination. Using expired eye products can lead to irritation, infections, and inflammation.
Powder products like eyeshadow, blush, and bronzer generally last longer, sometimes up to two years, but they are not immune to expiration. Changes in texture, odor, or color are clear indicators that a product should be discarded, regardless of the printed date.
Preservatives play a crucial role in extending shelf life, but “clean” or preservative-free formulas often have shorter usability windows. While these products appeal to ingredient-conscious consumers, they require more diligence when it comes to storage and replacement.
Improper storage also accelerates breakdown. Heat, humidity, and direct sunlight can compromise formulas, making bathroom counters one of the worst places to keep cosmetics. Keeping products tightly sealed and stored in a cool, dry place helps maintain their integrity.
Ultimately, makeup safety is about more than maximizing value—it is about protecting skin and eye health. When in doubt, replacing an old product is always safer than risking irritation or infection. Understanding expiration guidelines empowers consumers to make informed decisions without sacrificing beauty or wellness.
