How long does Kinvara Hyaluronic Youth Boost stay fresh after opening?

Each batch of product has a unique and fully traceable manufacture code that tells us when it was made. Our products are safe to purchase and use within 3 years of their manufacture. We only distribute products that will be used within this period. In addition, each product has a PAO or Period After Opening Symbol that indicates how long after the product has been opened it can be used for, which in this case is 6 months.
