Freeze dried facial mask, also known as freeze-dried powder facial mask and freeze-dried solid stock solution facial mask, refers to the ingredients such as the original solution, thickener and humectant of the falling facial mask, which are fused with the membrane cloth fiber, and vacuum freeze-drying is carried out using the freeze-drying technology of the freeze-drying machine, "sublimating the water to form a facial mask in the form of a solid dry film.
So what is freeze-drying technology?
The freeze-drying technology mentioned here usually refers to vacuum freeze-drying technology. Generally speaking, we can imagine that dynamic technology is an invisible hand, which can remove the water molecules without damaging the materials, leaving the remaining object structures and substances originally dissolved in water. For the freeze-dried facial mask, its production process can be simply described as: after preparing the familiar wet facial mask, it is not packaged directly, but frozen, and sent to the freeze-drying equipment to remove the moisture, leaving only the dry facial mask carrier and effective skin care ingredients dissolved in the moisture of the wet facial mask.
Therefore, as long as an appropriate amount of pure water is added to the dried facial mask before use (such as the amount of water originally contained before freeze-drying), the facial mask can almost return to the state before freeze-drying, so that the facial mask freshly prepared by your own hands can be used.
Difference between freeze-dried facial mask and ordinary facial mask:
Freeze dried facial mask can retain the higher activity of raw materials and retain the effective ingredients that are easy to oxidize and volatilize. Compared with ordinary facial mask, freeze-dried facial mask can bring the effective ingredients into play to a greater extent and have better skin care effects.
The facial mask paper and facial mask essence are sealed after being freeze-dried to isolate water and air, so the freeze-dried facial mask is not easy to breed bacteria, and the ingredients will be stored for a longer time and kept in a fresh state. Therefore, the freeze-dried facial mask is free of preservatives, safe and non irritating, suitable for any skin type, and very friendly to the skin.
