The shelf-life of unopened products is one year except for our masks.
Opened products have been given a 3-6-month shelf-life. The variance depends upon whether the product is left open, heated such as from being left in a car, cross-contaminated with other products, or touching of dropper tip to the skin or another surface, etc. All of these situations can significantly reduce shelf-life after opening.
