Lyophilized powder is a special preparation characterized by its ability to effectively maintain the activity and stability of ingredients, as well as its high moisturizing, anti-aging, antioxidant, anti-inflammatory and other effects. It is widely used in cosmetics, skincare products, and other fields as a high value-added cosmetic raw material. Lyophilized products are sterile powder injections made by freezing a medicinal solution into a solid state in a sterile environment, extracting it into a vacuum to sublimate and dry the water. It is made by using the vacuum freeze-drying method of a freeze-drying machine to freeze the water in the medicine liquid in advance, and then sublimating the frozen water in the medicine liquid in a vacuum sterile environment to obtain freeze-drying. In short, Freeze dried powder is a method of extracting water from a medicinal liquid in a low-temperature environment, while retaining its original medicinal properties.

Other benefits: In addition to the main benefits mentioned above, freeze-dried powder can also be used in other aspects, such as promoting skin cell repair and regeneration, enhancing skin immunity, etc. It can be used as a multifunctional additive in cosmetics and is suitable for various skin types.
In short, freeze-dried powder has been widely used and highly recognized in the field of cosmetics due to its unique preparation process and multiple effects.
Freeze dried powder is a preparation prepared through freeze-drying technology, and its main preparation process includes steps such as solution preparation, packaging, and freeze-drying.
The specific preparation process is as follows:
Solution preparation: Dissolve the required active ingredients in an appropriate solvent to produce a uniform solution.
Sub packaging: Divide the solution into small bottles or ampoules, usually with a volume of 0.5-1.0ml per bottle.
Freeze drying: Place small bottles or ampoules containing solutions into a freeze dryer and undergo processes such as low-temperature freezing and vacuum drying to sublimate the water and leave solid components behind.
Encapsulation: Encapsulate the freeze-dried formulation to maintain its stability and activity,lyophilized powder in a vial is very convenient.
lyophilized peptide is an effective method for drying heat sensitive products and substances that need to maintain biological activity. This method is to freeze the moisture contained in the product that needs to be dried at low temperature, and then dry it in a vacuum environment, allowing the moisture to directly sublimate from a solid state to water vapor and be eliminated from the product, thereby making the product active and dry. This method effectively prevents changes in the physical, chemical, and biological characteristics of the product, with minimal damage to the structure and characteristics of biological tissues and cells, allowing them to quickly enter a dormant state, effectively protecting the stability of many active ingredients in thermosensitive drug biological products. Proteins and microorganisms will not undergo denaturation and lose their biological activity.
Secondly, freeze-dried products have loose morphology and almost unchanged color after drying. After adding water, they can quickly dissolve and restore the physicochemical properties and biological activity of the original aqueous solution.
Thirdly, due to the fact that drying is carried out under vacuum conditions, it has a good protective effect on some easily oxidizable substances.
Fourthly, the moisture content of the product after freeze-drying is very low, which improves its stability and reduces the chance of contamination. This not only facilitates transportation but also extends the shelf life of the product.
