Hyaluronic acid gel is a very popular skin care product for girls, because it not only has many functions, but also has a very high cost performance in the market.

It can be used as hydrating cream, making cream, mixed with cream, repairing after sun exposure, effectively removing freckles, repairing acne and hydrating eye mask, but it needs to be used in different proportions for different purposes, and the best effect can be achieved if it is used properly. It is precisely because hyaluronic acid gel is safe and effective.

1, when hydrating cream

When used as a cream, you should not use too much. Massage more to make the skin fully absorbed. Don't use too much in summer! Hyaluronic acid gel may not moisturize enough in winter. It is best to use other creams or lotions after using hyaluronic acid gel. It is very good in summer. It is hydrating and not greasy. It's refreshing and comfortable to use.

Step 2 make a mask

Apply a thick hyaluronic acid gel after cleansing. If you don't wash it off at night, your skin will feel full and tender. Moreover, hyaluronic acid gel has a very good repair effect, which can repair the damaged tissues of your skin well, make your skin smooth and elastic, significantly reduce wrinkles, and make your skin white and translucent.

3. Hyaluronic acid gel and cream are mixed together.

Hyaluronic acid gel and cream can be used after being mixed at the ratio of 2: 1. It won't rub mud, and it is very moist, and it won't feel that the cream is too thick and dry. Moreover, the hyaluronic acid gel itself has a certain isolation effect, and the mixed isolation effect of the two will be better, the makeup will be easier and the makeup will be more natural and shiny.

Step 4 repair after sun exposure

Put this product in the refrigerator in summer. When the skin is sunburned or reddened by the sun, the mask paper is soaked in hyaluronic acid gel and applied to the face for about 15 minutes, which can effectively calm the sunburn stimulation. (You can also apply a thick layer on your face without mask paper, and keep it for about 15 minutes, then wipe off the gel that can't be completely absorbed. )

5, effective freckle

As long as the ratio of hyaluronic acid gel to water is diluted to 1:3 after washing your face, apply it evenly on your face, and massage the spotted parts more, which will promote skin absorption and enhance fragrance circulation. 1 three times a day, not too strong twice during the day, but a little stronger before going to bed. Note that freckle will take at least 3 months to be effective.

6, repair acne

Mature peas have pustules. You can squeeze them out with clean hands, and then rub hyaluronic acid gel on the wound, which can be used for multiple purposes and is very effective for peas to recover as soon as possible.

7, hydrating eye mask

When the eyes are dry or swollen, put the refrigerated hyaluronic acid gel on a cotton pad and apply it to the eyes to relieve the dry edema.

Extended data:

The production process and technology of hyaluronic acid gel determine the quality difference, so the products produced from the right source must have therapeutic effect in use. Generally speaking, there are three kinds of refining methods:

animal tissue

The main raw materials are cockscomb and bovine vitreous. Defat that raw materials with acetone or ethanol, dehydrate, soaking in distilled water, filter, treating with sodium chloride aqueous solution and chloroform solution, adding trypsin, keeping the temperature to obtain mixed solution, and finally treating with ion exchanger and purifying to obtain refined hyaluronic acid gel.

The extraction rate of this method is very low, only about 1%, and the separation process is complicated, which makes hyaluronic acid gel expensive, reaching 5000 US dollars/kg, which limits its large-scale use in cosmetics.

microbial fermentation

Fermentation broth with glucose as carbon source. Fermented in the culture medium for 48 hours, filtered to remove mycelium and impurities, and then obtained high-purity products through simple operations such as alcohol precipitation.

Hyaluronic acid gel prepared by fermentation method has the advantage that the molecular weight can be set according to the product design. The key of fermentation method lies in the selection of strains. At present, streptococcus, Lactococcus and so on are mostly used.

chemical synthesis

Adopt natural enzyme polymerization reaction; Firstly, the polysaccharide polymer was used to synthesize the "hyaluronic acid oxacyclopentene derivative", then hydrolase was added to make the derivative and enzyme form a complex, and finally the enzyme was removed from the reaction solution at 90 degrees Celsius to form hyaluronic acid gel.

The synthetic method can greatly reduce the manufacturing cost of hyaluronic acid, but the structure is not pure.
