You shouldn’t take an expired prescription. You don’t drink milk past the “use by” date. What about old makeup? How do we know when our makeup is expired? Formulas in makeup change as they age and there may be a build up of bacteria that could cause an infection. After you have opened up your product, there is a time limit on how long they are any good.
1. When you buy mascara, the box usually has an expiration date. Mascara tends to last 6-9 months.
2. Foundation can last from 6 months to one year. You may see streakiness and changes in color or texture as the formula breaks down and pigment separates from the rest of the product. If longer than two years, germs can buildup as the preservatives are less effective.
3. Cream eye shadows tend to stay fresh for about 9 months. Powdered eye shadow tends to last around 18-24 months.
4. Lipstick can last up to two years because it is oil based. Bacteria breeds more in water based products. After a year or two, the natural oils in lipstick can become rancid. If it smells or tastes strange, then toss it.
5. Moisturizer does go bad with time. If it is drying out, changing colors or smells funny it is time to toss it. Don’t use moisturizer that is over a year old.
6. Sunscreen lasts for about 6 months to one year. Over time, the effectiveness of the SPF will diminish. Also the active ingredients will separate and you will not get an even coverage when applied.
7. Makeup brushes carry germs and bacteria. It is important to wash your makeup brushes monthly.
8. Mineral makeup is as long lasting as any makeup product. However, it can still become contaminated if brushes are not cleaned timely and properly.
9. Anti-oxidant serums contain ingredients that do not last more than a year.
10. As a general rule: if your makeup smells, that’s a huge indicator hat you should not be using that product. Likewise, if the product has changed color or consistency, is cakey or has separated, then it’s time to toss it.
