Hyaluronic acid is so powerful

Hyaluronic acid is a nutrient present in the dermis of the human body. Its biggest function is to retain moisture, keep the skin from drying out, reduce the appearance of wrinkles, and make the skin shiny and elastic. This substance is widely used in the preparation and production of cosmetics to enhance its hydrating and moisturizing effects, and play a role in skin care and beauty.

1. Self-regulation

A large number of studies have shown that the moisture content of the human skin surface layer (stratum corneum) is about 15-30%. Values ​​lower or higher than this will make people uncomfortable, with a dry or greasy feeling. If this continues for a long time, the skin will become dry or chapped, causing the skin to lose elasticity, become rough and aged. After hyaluronic acid (HA) acts on the skin for internal conditioning, it can automatically adjust in different environments and always maintain the skin's moisture at 25-30%, keeping the skin moist and refreshed, making the skin more elastic, and playing a role in anti-wrinkle, delaying the aging of the entire skin, and beautifying the skin. Hyaluronic acid is one of the components of the human dermis. It has the ability to retain moisture at a level up to 100 times its own weight. Using skin care products containing hyaluronic acid HA can improve dry and wrinkled skin and restore its original smoothness and elasticity. Therefore, hyaluronic acid is the most ideal product for improving dry and aging skin.

2. From the inside out

Studies have shown that no matter how good the ingredients of cosmetics are, they usually cannot reach the dermis. In particular, due to the large molecular weight of hyaluronic acid HA, it is impossible for it to be absorbed by the dermis if it is only applied to the epidermis. Hyaluronic acid (HA) cosmetics only act on the surface of the skin where they are applied, increasing the HA content on the skin surface, playing a moisturizing and hydrating role. They are local and exogenous. Hyaluronic acid (HA) can be taken orally and absorbed through digestion, which can significantly increase the precursors of HA synthesis in the body, thereby increasing the synthesis of HA in the skin and other tissues, thereby increasing the skin's water retention, making it more elastic, and reducing wrinkles. Its beauty and health care effects are systemic. It increases the content of endogenous hyaluronic acid (HA) from the dermis to the epidermis, increases blood microcirculation, activates cells, and exerts a systemic effect. It is endogenous and is significantly different from the local use of cosmetics. Therefore, to maintain the function of collagen, it is necessary to supplement endogenous hyaluronic acid (HA), that is, external factors must work through internal factors.

3. Skin care and beauty

Hyaluronic acid (HA) can also improve skin growth conditions, provide a superior external environment for the synthesis of dermal collagen and elastic fibers, enhance the supply of nutrients, and achieve the effect of skin care and beauty. Studies have shown that hyaluronic acid HA can prevent the production of some enzymes in cells and reduce the formation of free radicals. It plays an important role in preventing free radicals from destroying cell structure, producing lipid peroxidation and causing body aging. Low molecular weight hyaluronic acid has anti-inflammatory effects, inhibits the production of pathogens, and keeps the skin smooth. It provides a suitable place for cell proliferation and differentiation, directly promoting cell growth, differentiation, reconstruction and repair, etc.

4. Medicinal value

Due to the effect of hydrogen bonds between monosaccharides on the straight chain axis of hyaluronic acid, the hyaluronic acid molecule presents a rigid spiral columnar structure in space. The inner side of the column has strong hydrophilicity due to the presence of a large number of hydroxyl groups. The hyaluronic acid molecules lock the bound water molecules in their double spiral columnar structure, making it difficult for water to be lost. Therefore, it has a special water-retaining effect. Theoretically, the water-retaining capacity can be as high as 500ml/g, and it is known as an ideal natural moisturizing factor. As we age, the amount of HA in the body decreases. Oral health supplements containing hyaluronic acid can replenish HA in the body, which has the effects of delaying aging and moisturizing the skin. It has been widely used in Japan, the United States and other countries. Hyaluronic acid has been used in medicine in eye drops, surgical materials and injections.
