Our face mask sachets are sold as single use, however our amazing community often tell us how there’s plenty of product left over, meaning you may get a second use! It really depends on how you apply and layer the face mask onto the skin. If you do choose to save some of the product and reuse it later, our advice would be to seal the remaining product in an airtight container and don’t leave it longer than 3 days, once opened. If you’re really lucky, you may have purchased one of our multi-use treatments such as the moisturizing hydrogel eye masks which contains 3 pairs! You’ll always know how much each pack contains or if there is more than one treatment in a sachet as it will state it clearly on the front of pack.
