mineral eyeshadow makeup that has not been opened has an endless shelf life if it is stored correctly (away from moisture, air, and light) and remains unopened. Depending on how often it is used and how often it is applied, we recommend mineral cosmetics be used within 24 months of opening the product.

When using concealer, should it be done so before or after applying foundation?

So, when you apply foundation, should you put concealer on first or last? The foundation should be applied first, and then the concealer should be dabbed on top of that. This is the correct order for applying the two products. Foundation will create that even canvas we talked about earlier, and then concealer can be used to spot correct any outstanding areas that need extra coverage.
