Nano Recipe Nano Ceramide 5000ppm 35g NMN 150,000ppm 10ml Both were purchased from the official website in September 2025. The expiration date is not listed on the NMN, so I'm not sure, but since it's only been a few months since opening, I think it can still be used. Please refer to images 3 and 4 for the remaining amount. Since it's a concentrate, please mix 1-2 drops with cream or serum and use. [About Shipping] * It will be wrapped in bubble wrap and shipped in a Yu-Packet Post mini envelope. Please understand.
