Shelf life of foundation

Check the ingredients: A water-based foundation will last up to 12 months, oil-based will last up to 18 months. You may find you need two different shades of foundation each year: One for summer when your skin is naturally darker & one for winter when you're lighter. Extra tip: If your water-based foundation dries out before it's expiry date, simply add a few drops of alcohol-free toner & shake to get rid of clumps. No need to do this to oil-based foundations. Because they contain oil, they will tend to separate. You have to shake anyway.
