Hyaluronic acid is also known as glycolic acid and hyaluronic acid. Hyaluronic acid originally exists in the dermal tissue of human skin and is responsible for storing water, increasing the volume of the skin and making it look full and elastic. It is the best moisturizing substance found in nature and is known as the ideal natural moisturizing factor. Research shows that 1 gram of hyaluronic acid can absorb 500 c.c. of water, which is equivalent to 500 times the water absorption capacity. Function 1. Hyaluronic acid HA, present in the skin, plays an important role in the metabolism of human epidermis. Destruction or disorder of hyaluronic acid HA in human body can cause diseases. The reduction and destruction of HA content in skin can cause skin water loss, wrinkle and loss of elasticity, so that the human epidermis aging, thus HA is also known as the anti-aging factor. 2, hyaluronic acid HA is one of the main matrix components of the epidermis and dermis of human skin, its physiological function is to enable the water into the cell space, and protein binding and the formation of protein gel, the cells stick together, play a normal role in cell metabolism. Playing the role of maintaining cellular moisture, protecting cells from pathogenic bacteria, speeding up the recovery of skin tissue, improve wound healing regeneration ability, reduce scars, enhance immunity and so on. 3, in medicine, hyaluronic acid HA is used in non-steroidal anti-inflammatory drugs, arthritis treatment, ophthalmology, cardiothoracic surgery auxiliary drugs. Hyaluronic acid is a multifunctional matrix, can improve the skin nutrition metabolism, make the skin soft, smooth, wrinkle, increase elasticity, prevent aging, in moisturizing and at the same time is a good transdermal absorption promoter. In addition, it can also promote cell growth, differentiation, reconstruction and repair, prevent the formation of free radicals, and avoid lipid peroxidation. However, hyaluronic acid is lost with age, causing the skin to lose its ability to store water. When the content of hyaluronic acid in the skin is lower than a certain level, the water content of the skin surface layer will gradually decrease, resulting in the aging of the stratum corneum, the skin looks rough, wrinkles and loss of elasticity. That’s why hyaluronic acid is so important to human beauty, it is the secret to make the skin freeze and even reverse age. So in daily life, timely supplementation of hyaluronic acid is the trick to stay young Oh!
