Yes, Dead Sea masks do expire.
According to information we have, a Mineral Mud Mask has a shelf-life of three years from the date of manufacture. You can find the expiry date on the bottom of the jar. After opening the mask, it should be used within 12 months.
Here's a breakdown of the expiration information:
- Shelf Life (Unopened): 3 years from the manufacture date.
- Expiry Date Location: Found on the bottom of the jar.
- Period After Opening (PAO): 12 months. This means you should use the mask within 12 months after opening it.
In summary, pay attention to both the manufacture date (for the unopened product) and the period after opening to ensure you're using your Dead Sea mask while it's still effective and safe.
