How long to use VA/VM serum after opening.
VA and VM Vitamin C products previously had a 1-year expiration date after opening, but we are changing the expiration date to 6 months after opening to keep the vitamin C fresher.
Therefore, the outer carton with the previous 1-year expiration date may be distributed together. In the future, we will change the expiration date of all outer boxes to 6 months after opening, and we would like to inform you that the expiration date of the outer box and the product may be different.
However, there is no problem with the skin even if you use it for 1 year after opening, but we recommend that you use it as soon as possible after opening and use it within 6 months to keep the vitamin C fresher.
We will always strive to sell good products.
