Color change due to oxidation of the vitamin serum.
Color change due to oxidation of the vitamin serum.
We would like to inform you that Pure Vitamin C Serum may naturally change color over time or when exposed to air, due to its high concentration of vitamin C.
This is a normal oxidation process, and you can continue to use the product with confidence when the serum turns a light lemon or yellow color.
However, if the serum turns brown, we kindly recommend using a new product to maintain the best possible condition.
To maintain product quality, please use the serum as soon as possible after opening and store it tightly closed, away from direct sunlight, heat, and humidity.
Thank you for your continued trust and support.
