Recently, one of the most popular beauty products is freeze-dried powder. Have you heard that the use of freeze-dried powder can accelerate the aging of the skin cells to fall off and the generation of new cells, so that the skin can recover to the best state. How can freeze-dried powder be best preserved? Must it be stored in the refrigerator?
Do you have to refrigerate the freeze-dried powder
Freeze dried powder is a kind of highly active substance, which will lose its activity when the temperature is too high. In order to maintain its biological activity, the freeze-drying process is used, that is, the main components are frozen at low temperature, then dried under vacuum, so the water sublimates directly. Therefore, the freeze-dried powder is best kept at low temperature, and the unsealed freeze-dried powder is also put in the refrigerator as far as possible. After the freeze-dried powder is unsealed, when it is mixed with the solvent into a liquid, it must be easily placed in the refrigerator, preferably kept at 2-8 ℃, and sealed as much as possible to prevent loss of activity.
How long can lyophilized powder last in the refrigerator
The opened freeze-dried powder should be kept in the refrigerator. It is recommended that it should be used up within one week. Although it is in the refrigerator, the activity of the freeze-dried powder in the non vacuum environment is still easy to be damaged, so it can not be preserved for too long, especially in summer, it must be placed in the ice box after opening.
Precautions for putting freeze-dried powder in refrigerator:
If there is stratification problem after the freeze-dried powder in the refrigerator is taken out, it only needs to be shaken evenly for use without affecting the effect. After use, it still needs to be placed in the refrigerator to keep low temperature and dry, to avoid the sunlight, and also needs to be used up as soon as possible.
How long is the shelf life of freeze-dried powder
The shelf life of different lyophilized powder is different, ranging from several months to several years. It is suggested that you inquire about it in combination with the product manual and the product information on the bottle. However, it is worth noting that once the lyophilized powder is dissolved, it should be used up as soon as possible, and the activity will decrease with the passage of time, and disappear completely after one week, so we suggest that the lyophilized powder that has been dissolved should be used up within three days.
Shelf life of lyophilized powder after opening:
The shelf life of lyophilized powder after opening and dissolving is only three days. If the lyophilized powder has deteriorated in less than three days, it can be sealed in the refrigerator and completely used up in three days.
