คำตอบ
Regarding the storage of Vitamin C E Ferulic (Lite):
- The 50ml PET amber pump bottle you are using is acceptable for storage.
- For optimal storage, it is recommended to use an opaque or UV-resistant plastic bottle.
- Storing the product in the refrigerator is also highly beneficial.
When the product expires due to air exposure, its color will gradually change to a dark yellow, eventually becoming almost like "yellow medicine". If the color change is significant or the product has exceeded its recommended shelf life, it is best not to use it.
