【什么是玻尿酸（HA）】

What is hyaluronic acid (HA)

玻尿酸（HA），又称为透明质酸， 意思是像玻璃一样的、光亮透明的，玻尿酸（HA）是人体内一种固有的成分，是一种天然酸性粘多糖，广泛存在于胎盘、羊水、晶状体、关节软骨、皮肤真皮层等组织。

Hyaluronic acid (HA), also known as hyaluronic acid, means glass-like, bright and transparent. Hyaluronic acid (HA) is an inherent component in the human body and a natural acidic mucopolysaccharide. It is widely present in tissues such as the placenta, amniotic fluid, lens, articular cartilage, and dermis of the skin.

1934年美国哥伦比亚大学眼科教授Meyer等首先从牛眼玻璃体中分离出该物质。玻尿酸（HA）以其独特的分子结构和理化性质在机体内显示出多种重要的生理功能，如润滑关节，调节血管壁的通透性，调节蛋白质，水电解质扩散及运转，促进创伤愈合等。尤为重要的是，玻尿酸（HA）具有特殊的保水作用，是目前发现的自然界中保湿性最好的物质，被称为理想的天然保湿因子。

In 1934, Meyer, a professor of ophthalmology at Columbia University in the United States, and others were the first to isolate this substance from the vitreous body of bovine eyes. Hyaluronic acid (HA) exhibits a variety of important physiological functions in the body due to its unique molecular structure and physicochemical properties, such as lubricating joints, regulating the permeability of vascular walls, regulating the diffusion and transport of proteins, water and electrolytes, and promoting wound healing. Most importantly, hyaluronic acid (HA) has a special water-retaining effect and is currently the best moisturizing substance discovered in nature, and is known as an ideal natural moisturizing factor.

【玻尿酸（HA）与人体】

Hyaluronic Acid (HA) and the Human Body

HA广泛分布于动物组织细胞外基质和细胞间质中，是机体的天然组成成分，主要分布在软结缔组织、玻璃体、皮肤、滑液中。人体中的玻尿酸（HA）含量约为15g，在人体的生理活动中发挥着重要作用。皮肤中的玻尿酸（HA）含量减少，皮肤的保水功能减弱，显得粗糙并产生皱纹；其它组织和器官中的玻尿酸（HA）减少，可导致关节炎、动脉硬化、脉搏紊乱和脑萎缩等，人体中玻尿酸（HA）的减少会产生早老症。

HA is widely distributed in the extracellular matrix and intercellular matrix of animal tissues and is a natural component of the body. It is mainly found in soft connective tissue, vitreous body, skin and synovial fluid. The content of hyaluronic acid (HA) in the human body is approximately 15 grams and it plays a significant role in human physiological activities. When the hyaluronic acid (HA) content in the skin decreases, the skin's water retention function weakens, making it appear rough and prone to wrinkles. A reduction in hyaluronic acid (HA) in other tissues and organs can lead to arthritis, arteriosclerosis, pulse disorders and brain atrophy, etc. A decrease in hyaluronic acid (HA) in the human body can cause progeria.

机体含有的HA一半以上存在于皮肤中。HA与其他硫酸化多糖、纤维性蛋白等组成含有大量水分的胞外胶状基质，维持正常的胞外空间，有利于营养物的供应和代谢物的排放。HA在皮肤中含量的高低，直接决定了肌肤的“视觉年龄”。皮肤中的HA的减少，造成肌肤保水功能下降，胶原纤维和弹性纤维得不到充足的水分而失去弹性，出现细纹、皮肤萎缩等初老症状。

More than half of the HA contained in the body exists in the skin. HA, together with other sulfated polysaccharides, fibrous proteins, etc., forms an extracellular gel-like matrix containing a large amount of water, maintaining a normal extracellular space and facilitating the supply of nutrients and the excretion of metabolites. The level of HA in the skin directly determines the "visual age" of the skin. The reduction of HA in the skin leads to a decline in the skin's water retention function. Collagen fibers and elastic fibers do not receive sufficient moisture and lose their elasticity, resulting in early aging symptoms such as fine lines and skin atrophy.

【人体缺少玻尿酸(HA）会怎样?】

What will happen if the human body lacks hyaluronic acid (HA)?

从25岁开始，人体内的玻尿酸会逐渐流失，30岁时仅剩年轻肌肤的65%，60岁时仅剩年轻肌肤的25%，玻尿酸（HA）随着年龄的增加而流失，长久下来，皮肤会逐渐失去弹力、光泽，老化、皱纹及松弛也会随之产生。

Starting from the age of 25, the hyaluronic acid in the human body gradually decreases. By the age of 30, only 65% of the young skin remains, and by the age of 60, only 25% of the young skin remains. Hyaluronic acid (HA) decreases with age. Over time, the skin gradually loses its elasticity and luster, and aging, wrinkles and sagging will also occur.

【产品性能】

Product Performance

a、保湿滋养 Moisturizing and nourishing

玻尿酸（HA）大量存在于年轻的人体皮肤中，由被称为成纤维细胞的特殊皮肤细胞在真皮内产生，随着年龄的增长，皮肤中 HA 的含量也会逐渐减少。HA能够结合并保留高达其重量 1,000 倍的水分，也因为这种特性，HA时常被用于各类护肤产品中，以此赋予皮肤丰盈年轻的状态。

Hyaluronic acid (HA) is abundantly present in the skin of young people and is produced in the dermis by special skin cells called fibroblasts. As people age, the content of HA in the skin gradually decreases. HA can combine and retain up to 1,000 times its own weight in water. Due to this property, HA is often used in various skin care products to give the skin a plump and youthful appearance.

b、紧致肌肤 Firm the skin

玻尿酸（HA）属于皮肤真皮纤维及细胞间的基质成分，能够帮助皮肤从体内及皮肤表层吸收水分，同时还能锁住细胞内的水分，延缓皮肤老化的速度，使皮肤看起来水润、有弹性。

Hyaluronic acid (HA) is a component of the matrix between dermal fibers and cells in the skin. It can help the skin absorb moisture from within the body and on the surface of the skin, while also locking in moisture within cells, slowing down the aging process of the skin, and making the skin look moist and elastic.

C、改善肤质 Improve skin quality

玻尿酸（HA）在保湿的同时又是良好的透皮吸收促进剂。能改善皮肤营养代谢，促进表皮细胞的增殖和分化、清除氧自由基，可预防和修复皮肤损伤。人类皮肤成熟和老化过程也随着玻尿酸（HA）的含量和新陈代谢而变化，它可以使皮肤柔嫩、光滑、去皱、增加弹性、防止衰老。

Hyaluronic acid (HA) not only moisturizes but also acts as an excellent transdermal absorption promoter. It can improve skin nutrition and metabolism, promote the proliferation and differentiation of epidermal cells, eliminate oxygen free radicals, and prevent and repair skin damage. The maturation and aging process of human skin also vary with the content and metabolism of hyaluronic acid (HA), which can make the skin tender, smooth, reduce wrinkles, increase elasticity and prevent aging.

D、温和抗敏 Mild anti-allergy

玻尿酸（HA）可以有效减少炎性因子的释放，帮助细胞抵抗外物刺激，降低皮肤过度敏感，并能够帮助皮肤细胞清除紫外线照射产生的活性氧自由基，减轻炎性反应，恢复皮肤健康状态。

Hyaluronic acid (HA) can effectively reduce the release of inflammatory factors, help cells resist external stimuli, lower excessive skin sensitivity, and assist skin cells in eliminating reactive oxygen species produced by ultraviolet radiation, alleviating inflammatory responses and restoring the healthy state of the skin.
