bareMinerals SPF15 foundation is chemical-free, and has a natural SPF 15. Our foundation proudly carries the Skin Cancer Foundation Seal of Recommendation. The best part about bareMinerals products is that they do not expire. The FDA requires expiration dates on all products that claim SPF (Sun Protection Factor) until they have passed at least 3 years of stability testing. For products such as bareMinerals, the FDA allows the expiration date to be removed when the appropriate testing information is available, and as long as the SPF product does not have dosage limitations. Therefore, we no longer print expiration dates on our products as they are unnecessary.
