The origin of hyaluronic acid skin care products
1. When did humans discover hyaluronic acid? The origin of hyaluronic acid?
Hyaluronic acid is an acidic mucopolysaccharide. In 1934, Meyer, a professor of ophthalmology at Columbia University, first isolated the substance from the vitreous body of the bovine eye. With its unique molecular structure and physicochemical properties, hyaluronic acid shows a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel walls, regulating proteins, water and electrolyte diffusion and operation, and promoting wound healing. Hyaluronic acid has a special water-retaining effect, and is the best moisturizing substance found in nature. It is called an ideal natural moisturizing factor.
2. Is hyaluronic acid produced by the human body? Why does hyaluronic acid decrease when people age?
Hyaluronic acid is an important component of moisturizing in the dermis layer of human skin. Its content will decrease with age, which will cause dry skin, lack of water and aging, resulting in wrinkles, roughness, dullness and uneven skin tone.
3. Does hyaluronic acid really work?
Human skin contains a large amount of hyaluronic acid. The maturation and aging process of human skin also changes with the content and metabolism of hyaluronic acid. It can improve skin nutrition metabolism, make skin soft, smooth, wrinkle-free, increase elasticity, prevent Aging, it is a good transdermal absorption enhancer while moisturizing. Used in conjunction with other nutrients, it can play a more ideal effect of promoting nutrient absorption.
4. The amount of hyaluronic acid applied
It is understood that the content of hyaluronic acid reaches the best 1% (the highest standard in Europe for deep moisturizing)
The higher the concentration of hyaluronic acid, the less suitable it is in cosmetic products. The addition of high concentrations of hyaluronic acid to cosmetic ingredients will cause great damage to the skin. Therefore, you should pay attention to the amount of hyaluronic acid used. Generally, 1 to 2 drops of hyaluronic acid is enough. Apply it all over the face and neck. If the amount is too large, it will not be absorbed and cause a burden on the skin.
Different molecular sizes of hyaluronic acid have different effects on beauty in different places
5. Where are hyaluronic acid skin care products extracted from?
For the question of where to extract hyaluronic acid, there are mainly three extraction methods:
were extracted from animal tissues,
The second is extracted from microbial fermentation,
The third is to use chemical synthesis methods to be refined.
