Hyaluronic Acid, Do You Really Know It?

What Is Hyaluronic Acid?

Hyaluronic acid is an acidic mucopolysaccharide. In 1934, Meyer, Professor of Ophthalmology, at Columbia University, first isolated the substance from the bovine vitreous body. Hyaluronic acid shows a variety of important physiological functions in the body with its unique molecular structure and physical and chemical properties, such as lubricating joints, regulating the permeability of blood vessel walls, regulating protein, diffusion, and operation of water and electrolytes, and promoting wound healing. It is particularly important that hyaluronic acid has a special water retention effect. It is the best moisturizing substance found in nature at present. It is the ideal natural moisturizing factor. A 2% pure hyaluronic acid solution can keep 98% water firmly.

Hyaluronic acid is a multifunctional substrate that is widely distributed in all parts of the human body. The skin also contains a lot of hyaluronic acids. It can improve skin nutrition metabolism, make skin tender, smooth, wrinkle, increase elasticity, prevent senescence, and be a good transdermal absorption enhancer at the same time. In combination with other nutrients, it can play a more ideal role in promoting nutrient absorption.

Hyaluronic acid, originally found in the skin, helps the skin absorb moisture from the body and skin and also enhances the skin’s long-term water retention. When hyaluronic acid absorbs moisture, the elastic fibers and collagen are in a moist environment, and the skin is elastic. However, the hyaluronic acid of the skin begins to lose from the age of 25. 30 years old is only 25% of the young. The moisture of the skin will follow hyaluronic acid and lose its elasticity and luster, and the aging phenomenon of wrinkles will appear for a long time.

With the growth of people’s age and the influence of nutrition, sunshine, environment, and other factors, the ability of the human body to synthesize hyaluronic acid gradually decreases, and the content of hyaluronic acid in the skin will gradually decrease.

The content of hyaluronic acid in human embryos was the highest and decreased gradually after birth. If the relative content of hyaluronic acid (HA) in the body of 20 years old was 100%, it decreased to 65%, 45%, and 25% at 30, 50, and 60 years old respectively.

When the content of hyaluronic acid in the skin is lower than a certain level, the moisture content of the skin surface will gradually decrease, resulting in the aging of the stratum corneum, the skin appears rough, wrinkled, lost elasticity, and aging, this phenomenon usually appears after 25 years of age.

This is also one of the main reasons for the skin gap between the middle-aged and the elderly.

At the same time, the destruction of hyaluronic acid in the skin of the human body is related to ultraviolet light, so people who have long been engaged in fieldwork, plateau life, and outdoor work are rougher than the indoor workers’ skin.

What Is the Effect of Hyaluronic Acid?

Moisturizing: Hyaluronic acid is the best moisturizing substance found in nature. It is known as the ideal natural moisturizing factor. A 2% pure hyaluronic acid solution can firmly lock 98% moisture. It can instantly moisturize deeply, increase skin elasticity and tension, help restore normal oil and water balance, and improve dry and relaxed skin.

Nutrition: It promotes the supply of skin nutrition and waste, so as to prevent skin aging.

Rhytidectomy: hyaluronic acid can penetrate into the dermis, reorganize the reticulate structure of the dermis, restore the water-clotted environment of the dermis, fill the skin with the collapse of the collagen fiber break, and stretch the wrinkles.

Sunscreen repair: hyaluronic acid can promote the increment and differentiation of skin epidermal cells, and remove the oxygen free radicals produced by ultraviolet radiation, which can promote the regeneration of the skin of the injured part, and also prevent and repair the skin redness, blackening, and dehydration of skin caused by sunburn.

What Kind of Hyaluronic Acid Skincare Products Are Used?

Moisturizing and barriers are the dual mission of skincare. The real high-quality hyaluronic acid must be the organic combination of macromolecule and small molecule hyaluronic acid. Large molecules of hyaluronic acid can not penetrate the skin but can form a protective film on the skin surface, isolating the invasion of external bacteria, dust, and ultraviolet. Small molecules of hyaluronic acid can penetrate into the skin, provide a suitable place for cell proliferation and differentiation, and play a role in replenishing water and water, making skin compact, smooth, and tender.

One of the culprits of skin problems is water shortage. Replenishment is the key to skincare. Hyaluronic acid only uses the best moisturizing, and the highest purity of skin to repair skincare products can completely solve skin problems, and skincare will be more effective.
