In the field of skincare and beauty, freeze-dried powder has gradually gained popularity among consumers due to its unique preparation technology and significant effectiveness.
1. What is Freeze-Dried Powder?
Freeze-dried powder is a powdered product prepared using freeze-drying technology. It is produced by freezing the liquid medicine in a sterile vacuum environment at low temperatures, followed by sublimation drying to remove water, thus forming a sterile powder.
Freeze-dried powder can be considered as the solidified form of active liquid substances, effectively preserving the activity of its ingredients and quickly returning to a liquid state upon dissolution.
2. Why Use Freeze-Drying Technology?
The adoption of freeze-drying technology is primarily based on several considerations:
- Preservation of Activity: Many skincare ingredients are prone to deactivation in liquid form, while freeze-drying technology converts water into solid ice at low temperatures, avoiding ingredient degradation caused by high temperatures, thereby preserving their activity.
- Extended Shelf Life: By removing water from the medicinal liquid, freeze-drying technology prevents microbial growth, thereby extending the product’s shelf life. Additionally, lacking moisture makes freeze-dried powder less susceptible to deterioration during transportation and storage.
- Convenient Usage: Freeze-dried powder is convenient to carry and store. It can be easily dissolved into a liquid form by adding an appropriate solvent, facilitating user-friendly skincare applications.
