This is Ellie by Jay Abecktowa, purchased in 2025. The volume is 30ml, and all three bottles are new and unopened. They have been stored in a refrigerator. The expiration date is January 1, 2027. It has a very high concentration of vitamin C, which is effective for skin blemishes. You can use it mixed with Pavel, or add a few drops to other lotions. Instant purchase is okay.
