between Vitamin CE Ferulic (Lite) with this Stabilized Vitamin C (Natural-C Glycol™) Serum can be bought and stored. If not open for how long? If opened, how many days will the oxidized time be used?

permission to comment normal products with วิตซี is the main component. Store it at room temperature for about 15 days, it will begin to change color to light yellow. keep going up If stored in the refrigerator, it will last much longer. but even dark yellow Features in whitening still very good วิตซี to สาร whitening The best สาร whitening I've ever used.

Hello, due to environment variables, both temperature levels and the amount of light affect the age of Vitamin C , it is difficult to answer clearly, but in the case of opening the package. If stored in the refrigerator You can expect to be at least 12 months old.
