What is it?

Hyaluronic acid is a kind of by DN - acetylglucosamine and D - glucuronic acid of the structure unit of macromolecular polysaccharide, a rigid cylindrical spiral on the space structure, produce strong hydrophilicity, and combined with the water molecules lock it in the double helix columnar structure, make the moisture not easily loss, so it is of special water effect, is currently the best moisturizing effect substance found in nature, known as the ideal Natural moisturizing factor, NMF).
Hyaluronic acid is a humectant, which is a category of skin care ingredients that are hygroscopic, meaning they draw moisture from their surroundings. Hyaluronic acid's moisture-binding characteristic is exceptionally important when it comes to skin aging. It is favored by cosmetic formulators and has a wide range of applications in the cosmetics field.

FAQ

1.Q: What is the difference between high molecular weight and low molecular weight?

A:The content of HA added in general cosmetics is 0.1%-0.5%,which can significantly improve the taste and grade of cosmetics.The skin care function of HA varies depending on the molecular weight.The higher the molecule,the larger the molecule,the thicker the consistency of the prepared stock solution,the moisturizing surface,and the formation of a protective film on the skin surface.The lower the molecule,the smaller the molecule and the better permeability,but the prepared stock solution has a lower viscosity and is deeply moisturizing.
1) High molecular weight HA: fast film formation,good moisturizing effect,suitable for making facial masks,creams,emulsions.High molecular weight HA molecules are entangled with each other and can form a "water film" on the skin surface,which has a moisturizing and water-retaining effect.Under normal circumstances,HA with a molecular weight of 1 million to 1.5 million works best as a cosmetic moisturizer.
2) Low-molecular-weight HA: It is absorbed through the skin and is suitable for making toners,toners,and essences.Low-molecular-weight HA is a linear molecule that can quickly enter the dermis from the surface of the skin to increase the content of HA,improve microcirculation,and enhance skin moisture retention Ability and flexibility.

2.Q: Can high and low molecules be used together?
A: Yes,the same half of the amount is enough.High and low mixing effect is better.

3.Q: How to use hyaluronic acid (hyaluronic acid)?
A: First,mix 1 gram of powder,100 ml of purified water,and 0.5% antibacterial agent to make a 1% stock solution,and let it stand for 48 hours to completely dissolve it before use.

Usage:
80ml purified water + 20ml stock solution = moisturizing liquid
or
80ml pure lotion + 20ml original solution = moisturizing essence
or
add it as a moisturizer to make skin care products (toner,essence,lotion,cream,mask,etc.),the addition amount is 5-20%.

4.Q: How to store the prepared stock solution?
A: If no antibacterial agent is added,keep it in the refrigerator and keep it sealed,and use it up within 15 days.In the case of adding 0.5% antibacterial agent,sealed and stored in the refrigerator,the shelf life can be extended by 3 months.

5.Q: Can the stock solution be used directly?
A: The original solution is not used directly,the concentration is large,but the moisturizing effect is poor when used directly,and the skin becomes dry after using it.

6.Q: How to judge the deterioration of the prepared stock solution?
A: The smell becomes sour,the state becomes turbid,and the consistency becomes thinner.
