Mesoceutical VC Serum Advanced 20ml High Concentration Vitamin Unused. The outer box has been opened once to check for broken bottles. Please purchase only if you understand this. It will be wrapped in bubble wrap and shipped via Yu-packet Plus. The price has been significantly reduced from the original price, so price reduction is not possible. *Due to the high concentration, those with sensitive skin may experience some tingling. There are minor scratches on the outer box due to home storage. Please refrain from purchasing if you are concerned about this. I purchased a bulk order during a salon campaign, but it doesn't quite suit my skin, so I will give away the unopened one.
