Makeup has become an essential part of our daily routine. However, many of us tend to forget that makeup, like any other product, has a shelf life. Using expired makeup can be detrimental to our skin and health. In this blog post, we will discuss the science behind makeup expiration and when it's time to throw it away.
What happens when makeup expires?
Like any other product, makeup contains various ingredients that have a limited shelf life. When these ingredients begin to degrade, they can cause changes in the texture, colour, and scent of the product. These changes can be an indication that the makeup has expired and is no longer safe to use.
Expired makeup can also harbour harmful bacteria that can cause skin irritation, infections, and other health problems. Makeup that has been exposed to air and bacteria over time can cause breakouts, acne, and other skin issues.
The shelf life of makeup depends on several factors, such as the type of product, how it is stored, and how frequently it is used. Below is a general guide to when makeup products should be thrown away.
When to throw away makeup?
Foundation: The shelf life of foundation varies depending on the type and formula. Liquid foundation typically lasts for 6 to 12 months, while powder foundation can last up to two years. Once the product starts to separate or develop a strange odour, it's time to toss it.
Mascara: Mascara has the shortest shelf life among all makeup products due to its liquid formula. It should be replaced every three months to prevent bacteria buildup and eye infections. If the mascara starts to dry out or develop clumps, it's time to throw it away.
Eyeliner: Pencil eyeliner can last up to two years, while liquid eyeliner should be replaced every six months. If the eyeliner changes colour or starts to dry out, it's time to let it go.
Lipstick: Lipstick can last up to two years, but it should be thrown away if it develops a strange odour or changes colour. Lip gloss, on the other hand, should be replaced every 6 to 12 months.
Powder products: Powder products, such as blush and eyeshadow, can last up to two years if they are stored in a cool, dry place. If the powder products become hard or develop a strange odour, you should get rid of it.
Most makeup in the UK has a code on the product to let you know how long you have to use the product before it expires. The symbol is a pot with a number and the letter M. If it says 12M then you have 12 months to use that product from when you open it.
It's essential to keep track of when you first opened a product and how frequently you use it. It's also important to clean your makeup brushes regularly to prevent bacteria buildup.
In conclusion, makeup expiration is a real issue that can have adverse effects on our skin and health. By following the guidelines above, you can ensure that your makeup products are safe to use and help you look and feel your best. Remember, if in doubt, it's always better to remove it.
