2. The content of hyaluronic acid in human body is about 15g, which plays an important role in human physiological activities. The content of hyaluronic acid in the skin is reduced, and the water retention function of the skin is weakened, which makes it rough and wrinkles appear. The decrease of hyaluronic acid in other tissues and organs will lead to arthritis, arteriosclerosis, pulse disorder and brain atrophy. The decrease of hyaluronic acid in human body will lead to premature aging.
3, oral hyaluronic acid increases the body content, which can supplement the hyaluronic acid lacking in the human body. Hyaluronic acid can make skin moist, smooth, soft and elastic through digestion and absorption; It can delay aging and prevent arthritis, arteriosclerosis, pulse disorder and brain atrophy. Oral hyaluronic acid can make people full of energy and youthful vitality.
Extended data:
Hyaluronic acid is a kind of medicine, which is essential in many projects such as wrinkle removal and face-lifting. Hyaluronic acid, also known as hyaluronic acid, is an extracellular matrix component and a natural filler in the skin, which plays a role in moisturizing, repairing and nourishing the skin.
The skin structure of human body includes epidermis, dermis and subcutaneous tissue. The epidermis is located on the surface of the skin and is the protective barrier of the skin. In general, its water content is 20%~35%. When the moisture content of epidermis drops below 10%, people will feel dry skin. The dermis is under the epidermis, and its main components are various fibers and the matrix between fibers.
Matrix can combine a lot of water, which is an important material basis for dermal tissue to maintain water. Hyaluronic acid is one of the most abundant matrices in dermis. If the hyaluronic acid in the dermal matrix is reduced, it will lead to the reduction of water content, which will lead to dry skin, dull skin, decreased elasticity and wrinkles.
Therefore, hyaluronic acid for external use can absorb water from the environment and "lock" it on the epidermis; At the same time, a small amount of hyaluronic acid infiltrated into the dermis can absorb water from the dermis and transfer it to the epidermis, thus achieving the moisturizing effect from the inside out.
In beauty institutions, hyaluronic acid is generally used by injection. As a tissue filler injected into facial tissue, it can support the filling, thus achieving the purpose of wrinkle removal. Hyaluronic acid is introduced into the dermis through a very fine needle. When the injection amount is small, it can be used to fill tiny wrinkles such as frown lines, crow's feet lines, decree lines or scars on the skin, making the skin smooth and elastic. When injected in large quantities, it can be used to reshape local appearance, such as rhinoplasty, chin augmentation and lip augmentation.
It should also be noted that injection of hyaluronic acid may cause allergic reactions, facial itching, redness, pain, infection, scar formation, local skin necrosis and other adverse reactions. If injected improperly, hyaluronic acid can not be treated in time when it enters blood vessels, and it may also cause serious complications such as blindness, cerebral infarction and even death. The following five groups of people should not be injected with hyaluronic acid:
People younger than 18 years old; Local skin has inflammation and infection; Recent use of anticoagulant drugs or abnormal coagulation; Pregnant and lactating women; People allergic to hyaluronic acid. Injection of hyaluronic acid must go to a regular medical institution, select qualified products, and be injected by experienced doctors with corresponding professional qualifications.
