How Long Does Mascara Last?

The shelf life can vary depending on the type and how it is stored. However, most have a shelf life of about three months.

Factors Affecting Mascara Shelf Life

Several factors can affect the shelf life of mascara:

• Type of mascara:

  Waterproof products may have a shorter shelf life than water-soluble products.

• Storage:

  Storing it in a cool, dry place can help extend its shelf life.

• Frequency of use:

  If you use it frequently, it may expire sooner.

Tips for Extending Mascara Shelf Life

Here are some tips for extending the shelf life:

• Clean the wand:

  Clean the wand with a tissue or cotton swab after each use.

• Avoid pumping:

  Pumping the wand can introduce air into the tube, which can cause it to dry out more quickly.

• Store properly:

  Store it in a cool, dry place, away from direct sunlight.

• Don’t share:

  Sharing it can increase the risk of bacterial growth.

The Science Behind Mascara Expiration

Mascara contains a combination of ingredients, including waxes, pigments, and preservatives. Over time, these ingredients can break down, leading to changes in it’s texture and composition. Bacteria can thrive in the moist environment of their tubes, especially if it is not stored properly.

The Risks of Using Expired Mascara

Using expired products can pose several risks to your eye health. Bacteria can cause eye infections, such as conjunctivitis, which can lead to redness, itching, and a watery discharge. Expired products can irritate your eyes and cause dryness, redness, or swelling.

When to Replace Your Mascara

If you notice any signs of expiration, it’s time to replace it. It’s also a good idea to replace it every three months, even if it doesn’t appear to be expired.
