Our products are manufactured and packaged fresh, within 2-3 weeks of the date of your purchase.
It is safe to assume that you have at least 11 more months after the purchase date. This period can be 23 months if you keep the gels in your fridge – not the freezer.
It is hard to put a specific expiration date on the product, because it depends on the storage conditions.
Even if they expire, they are not harmful, so there is no need to worry about using expired gels. An expired teeth whitening gel loses the whitening ability and turns into water with a lot of oxygen molecules inside. Keep using your whitening products until they turn into water.
