One Skin Face Serum Refill NEW in box

The first skin longevity treatment that extends skin health on the molecular level to address aging from within. Formulated for areas of your skin that are most exposed to environmental damage, including your face, hands, and neck. This is to go into the Oneskin plastic shell, not included. There is no expiration date on the product but it does have a lot # which you can see in the last two photos. I hope that helps!
