Formulated with the highest concentration of One Skin’s OS-01 peptide to help target aging at the molecular level, OS-01 EYE strengthens and visibly firms the delicate skin around the eyes. **Reusable clear outer shell and lid not included** Somebody asked me for the expiration date, and there isn’t one, but there are lot numbers on the bottom of the boxes. I’m selling two of these so if you purchase this, please tell me which lot number you want and I’ll send you that one.
