How long can you use a skincare product after the expiration date?

Most open products lose their effectiveness after a year and some even sooner, according to cosmetic chemist Ni'Kita Wilson. Expired products may not only lack potency, but can also cause an adverse skin reaction. If the product does not have this symbol on the packaging, one or two years is a good rule of thumb for shelf life, unless otherwise stated on the packaging. While products may vary, in general, unopened products have a shelf life of about two years when properly stored, Stenzel says.

After opening a product, it must be used as directed, within one year. Of course, this does not apply to over-the-counter products, such as sunscreens or acne formulas, that have an expiration date indicated on the packaging. According to Oprah, moisturizers can last two or three years if they are sealed, but they should be used within a year if opened. Face masks, eye creams, and skin peels have similar shelf life and use.

Therefore, it is important to understand those limitations before attempting to use them after they have expired. Products containing acids such as salicylic acid or glycolic acid should not be used after their shelf life, which is usually around a year. Products with acids often become more potent (and more irritating) over time. You risk damaging the skin barrier or even causing a chemical burn if you use an acid that is too strong for your skin.

Whether it is moisturizing cream or mask, the preservatives in the products only last for a while after opening, and the stability of the ingredients also has a shelf life. The hard part is that only products regulated as over-the-counter drugs (ie,. The average expiration date for beauty products depends on when you first use them and how the product is packaged and stored. We all know the negative side effects of eating expired foods, but many of us don't take beauty expiration dates so seriously.

For example, treatment products that come in a bottle expire after one year if they are not opened, but must be discarded after six months if the seal is broken. If it smells a little “bad” or if the oil in the product is on top of the rest of the product, that's a big warning sign, Brown said. Favorite beauty products like retinol, hyaluronic acid, glycolic acid and vitamin C are relatively unstable if exposed to oxygen, so if you're incorporating these ingredients into your skincare routine, it's a good idea to invest in products that come in a tube with a pump instead of a open bottle. Evans said.

The only thing you can notice is that the product will not be as fresh or as vibrant as it would otherwise have been. We know that it seems safer to preserve a product with natural ingredients, but they are simply not as effective as synthetic alternatives. The app then notifies you a month before the product expires and you have more than 850 hair, makeup, skin and fragrance products to get, Brooks said. Here's how long your favorite beauty products actually last and tips on how to keep them fresher for longer.

Most products contain preservatives to stay fresh longer, but over time, even preservatives lose their effectiveness, sellers said. Here are some simple tips to extend the shelf life of your products, keeping your skin and body as healthy as possible. In an ideal world, all beauty products would be labeled with an “expiration date” and instructions on how long to use them after opening them. In addition to health problems, Stenzel points out that a product will simply not be as effective over time, another reason to abandon it.

If you use skin care regularly, you should have no problem finishing a product in less time. Compound products with almost no water (such as powders) last the longest, because almost nothing can grow in this type of product. Some of the common culprits confirmed by the FDA are dipping your fingers directly into bottles of face masks and creams, using unsanitary applicators, and exposing products to moisture or extreme temperature changes. They range from unique organic products that are only available through online retailers to ubiquitous compounds found on pharmacy shelves.
