Opened cosmetic products should be used within 6 months to 2 years from the opening - depending on the type product.
Powders can be used for up to 2 years from opening, whereas mascaras should be used within 6 months of opening.
The shelf life of unopened cosmetics can range anywhere from 2-5 years, depending on the product.
Well-formulated products will have a longer shelf life as opposed to cheaper quality products.
Mirenesse only uses the highest quality of ingredients so the shelf life for our products will be on the longer end of the spectrum.
Unopened products are not a ground for bacterial growth, so typically the clock will start ticking once the product has been opened.
Proper storage is key - it is very important to keep your products out of high temperatures & humid environments. The best place to store your products is in a dark, cool & dry environment.
As long as these products have been stored in a suitable environment then they should still be fine to use.
