Pure hyaluronic acid powder

Hyaluronic acid (HA) is a straight-chain macromolecular mucopolysaccharide composed of repeating disaccharide units of glucuronic acid and N-acetylglucosamine. It is largely composed of the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cock's comb, etc. The commercial HA is

usually a sodium salt, called sodium hyaluronate, usually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several tens of thousands to several million. Its aqueous solution has outstanding moisture retention, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacies and health and beauty foods.

Main function:

* Keeps the skin plump and soft

* Reduce signs of aging

* Increase skin hydration

* Avoid UV damage to the skin

Method for preparing 1% hyaluronic acid stock solution:

If there are still flocks, it is normal. After being placed for 12-24 hours, it will be transparent and have a slight foam. It is a hyaluronic acid stock solution, also called 1% hyaluronic acid water stock solution.

Production and use method 2:

1. Add 1g of hyaluronic acid powder to 99ML of purified water or distilled water until completely dissolved (this process usually takes 12 to 24 hours) to obtain 100g of a 1% aqueous solution of hyaluronic acid. This solution is not recommended for direct use. It can be diluted 5 to 10 times with water or pure dew.

2. Hyaluronic acid is also a good carrier in addition to the moisturizing effect. It can be combined with various plant extracts and water-soluble ingredients. It is also dissolved in a solution before being used in the same formula. Make a variety of essences and masks.

Hyaluronic acid (hyaluronic acid) moisturizing essence production method3:

80 ml pure dew + 20 ml hyaluronic acid solution + antibacterial agent 5 drops of water is the moisturizing essence of hyaluronic acid

Store in a cool dry place. Restart.

Storage of hyaluronic acid solution:

You can store 1% hyaluronic acid solution in the refrigerator and use it as needed.

If prepared and stored correctly, the HA solution should be kept for at least 48 to 72 hours once refilled!

You should not attempt to store the HA solution at room temperature without adding a preservative.

The longest safe time you can keep the HA solution refrigerated without deterioration depends on your ability to maintain a sterile solution! Bacterial contamination of the solution can cause the solution to deteriorate and lose its thickness (viscosity).

If the solution becomes thinner or loses its thickness and viscosity over time, it will be damaged and must be discarded!
