Keep in mind which formula your foundation is made out of, as the two have separate expiration dates. Oil based foundations will last around 18 months and water based foundations have a 12 month shelf life. Prolong the life of your foundation by practicing sanitary application techniques, it’s crucial to keep bacteria at bay.
A foundation with a pump is ideal for keeping your makeup routine sanitary, if your foundation doesn’t have a pump, make sure to have hand sanitizer within reach at all times.
Remember, you may keep two shades in your collection for your winter and and summer skin colors.
