The Dangers of Using Expired Makeup | As Featured in Daily Mail

Dr. Alexandra Bowles was recently featured in The Daily Mail’s article, “Martha Stewart sparks concern after revealing she has been using the same liquid eyeliner for 20 years.” Today, Dr. Bowles expands upon the insights she shared in this article, including the risks of using expired makeup and how to know when it is time to say goodbye to a product.

What are the risks/dangers of using eyeliner that’s 15 to 20 years old?

Using eyeliner that is 15 to 20 years old can be very harmful to your eye health. Over time, cosmetics can become breeding grounds for bacteria and fungus, especially if they’ve been used repeatedly or stored improperly. These microorganisms can lead to eye infections, such as conjunctivitis or stye. This may even cause more severe conditions if the infection spreads. Additionally, the preservatives in the product, designed to prevent microbial growth, degrade over time, further increasing the risk of contamination. Beyond infections, the formula of older eyeliner may break down. This can potentially cause irritation, allergic reactions, or physical damage if the product flakes or becomes unstable. The delicate skin around your eyes and your vision are too important to take these risks. Expired makeup should always be discarded.

How long should people be keeping their eyeliner before throwing it away?

Eyeliner has a limited shelf life, which varies based on its type. Pencil eyeliners can typically last up to 24 months because sharpening them removes the exposed surface and reduces bacterial contamination. In contrast, liquid or gel eyeliners have a shorter lifespan, generally 3 to 6 months. This is due to their higher moisture content, which makes them more susceptible to bacterial growth. It’s important to regularly inspect your eyeliner for changes in texture, smell, or performance. These changes can indicate that it’s no longer safe to use. I recommend storing your products properly in a cool, dry place. I also recommend avoiding sharing your makeup with others. These habits can help minimize contamination and ensure safer use during its shelf life.

What should you do if you run into a similar problem as Martha, where your favorite eyeliner has been discontinued? Is it ever safe to use old eyeliner?

If your favorite eyeliner has been discontinued, it’s best to resist the temptation to use an expired product, as doing so can put your eye health at risk. Instead, explore alternatives, such as finding a similar product from another brand or consulting custom-blending services that recreate shades or formulations using fresh, safe ingredients. While it might feel sentimental to keep or use a discontinued eyeliner, the potential for bacterial contamination, irritation, or infection outweighs any benefit. Prioritize your safety and consider updating your makeup collection with newer, high-quality products that align with your preferences and needs.
