Used Item FARMACY Serum I used this serum a few times after purchasing it, but it didn't agree with my skin, so I stopped using it and have been storing it. It's about 90% full. I thought it would be a waste to throw it away, so I'm offering it to someone who understands. Purchased from the official website about two years ago. The number on the bottom says 2026, but I'm not sure if that's the expiration date. Thank you.
