Add 1 g of hyaluronic acid powder to 99 ML of purified water or distilled water until it is completely dissolved (this process usually takes 12 to 24 hours) to obtain 100 g 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 different essences and masks
Hyaluronic acid (hyaluronic acid) moisturizing essence production method3:
80ml of pure dew + 20ml hyaluronic acid solution + antibacterial agent 5 drops of water is the hyaluronic acid moisturizing essence
