Sodium Hyaluronate And Its Effects
Sodium Hyaluronate and Its Effects
Hyaluronic acid is also known as hyaluronic acid (HA). Sodium hyaluronate is the sodium salt form of hyaluronic acid, which has the same effect as hyaluronic acid and is widely used in cosmetics due to its better usability and operability.
Hyaluronic acid is an acidic mucopolysaccharide macromolecule widely found in human and animal connective tissues. It has important functions in the body such as retaining water, regulating osmotic pressure, maintaining tissue morphology, as well as lubricating, diffusing barriers, and buffering stress. Starting from the age of 25, the hyaluronic acid in the human body will gradually be lost, at the age of 30 only 65% of the young skin is left, at the age of 50 only 25% of the young skin is left. Hyaluronic acid is lost with the increase of age, in the long run, the skin will gradually lose its elasticity, luster, aging, wrinkles and sagging will also occur.
Sodium hyaluronate has the same high hygroscopicity in both low and high humidity conditions, automatically regulating and maintaining the skin's moisture level at 25-30%, and is known as the "Key to the fountain of youth". Therefore, it is widely used as an ideal natural moisturising factor. Large molecule sodium hyaluronate can form a breathable film on the surface of the skin to help the skin lock in moisture and protect the skin from damage by blocking the intrusion of foreign bacteria, dust, and ultraviolet rays. Small molecules of sodium hyaluronate can quickly penetrate into the dermis, slightly expanding capillaries, promote blood circulation, improve metabolism, promote the absorption of nutrients into the skin cells, with wrinkle wrinkle, enhance skin elasticity, and slow down the function of skin aging.
Sodium hyaluronate is now widely used in medicine, cosmetics, food and textiles and other fields. Research has proved that sodium hyaluronate has the functions of moisturising, lubricating, antioxidant, anti-apoptosis, anti-aging, promoting penetration, anti-inflammation, barrier repair, etc. It can be used in cosmetics to play a unique role in protecting the skin, keeping the skin moist, smooth, delicate, soft and elastic, and it has the functions of anti-wrinkle, anti-ageing, cosmetic care and restoring physiological functions of the skin.
Sodium hyaluronate has a very strong ability to absorb water, and the water adsorbed by the pro and adsorption is about 500-1000 times of its own mass, so it is recognised as a natural moisturising factor.
Role of sodium hyaluronate in skin cosmetology
1. Natural moisturising factor
Sodium hyaluronate can absorb water from the air into the skin, helping the skin to retain moisture.
2.Repair damaged barrier
Damaged skin barrier is the main cause of decreased water locking power, sodium hyaluronate can repair damaged skin barrier and prevent water loss.
3.Improve acne skin texture
Deep hydration, improve the imbalance of water and oil, maintain the permeability of pores, so that acne has no place to take root.
4.Improve skin aging
Continuously replenish the skin with sodium hyaluronate ingredients, so that the basal layer is always hydrated and full of water, so as to achieve the effect of smooth and delicate skin.
5. Full and lustrous skin
The hydrophilic factor of sodium hyaluronate can form a full water film on the surface of the skin, visually giving the effect of fullness and elasticity.
In our body, 50% of sodium hyaluronate exists in the dermis of the skin. Sodium hyaluronate + collagen + elastin together form the skin elasticity network, which maintains the stability and elasticity of the skin tissue. However, with age, cell metabolism slows down, the ability of the human body to synthesise sodium hyaluronate gradually decreases, the content of sodium hyaluronate in the skin is getting lower and lower, collagen fibres and elastin fibres in the skin do not get enough water, resulting in loss of elasticity of the skin and the appearance of wrinkles, so through the exogenous sodium hyaluronate supplementation is the supplementation of endogenous hyaluronan in the human body.
