Hello
1. Sediment of วิตซี is not soluble. The sediment from the old bottle has dried. and then share a new bottle to use Store in the refrigerator as white crystals. No matter how much you shake, it won't dissolve because
because Vitamin C is highly concentrated. There may be some precipitation in the event that The product goes through different temperatures (hot-cold). If it is precipitated, it will not be able to melt back into the formula. But usually the precipitation will not occur to such a degree that the efficiency will be lost.
2. วิตซี new lot, different smell
smell of raw material in each lot There will be some changes up and down. This is normal for both raw materials that are natural substances. and the kind that is synthetic
3. วิตซี The new lot is not as good as before. The feeling of using the back lot, feeling that the face is not full. Same as the first lot ever ordered Or is it because our skin is used to it? First time ordering a small bottle. The last time after ordering 1 kg
is normal for my skin's response. When the skin is nourished with only one ingredient for a long time It is similar to the skin that has been fully absorbed by the ingredients. If used continuously, it will not get better results. But at least the results should be the same, which means the fullness of the face should not be reduced, but more results cannot be expected. (more full) and comparing that More full or the same is difficult to do with the naked eye. Usually, you need to use various measuring tools to help you know the results that are comparable.
