Hyaluronic acid can help the skin absorb a lot of water. With water, the skin will naturally remain elastic and soft. Not long ago, we could only supplement hyaluronic acid to the skin by drug injection. Medical skin care products can use a small amount of hyaluronic acid as humectant, and pretend that hyaluronic acid compressed package with molecular weight of one million is applied to the skin, so that it can absorb about 1000 times its own weight, thus supplementing epidermal cells and smoothing wrinkles. Although the effective time is not as good as direct injection, it can be supplemented every day to make the cells naturally full.
Restoration and water resources protection
The English name is hyaluronic acid, which is a transparent colloid. It can instantly moisturize deeply, increase skin elasticity and tension, help restore normal oil-water balance of skin, and improve skin dryness and relaxation. Hyaluronic acid is also an important component in skin, which can repair epidermal tissue. When the skin tissue is irradiated by UVB rays, the skin will be sunburned and inflamed, and the dermal tissue will stop producing hyaluronic acid, and at the same time accelerate the decline of hyaluronic acid. Hyaluronic acid is rich in connective tissue and dermis of human body, which has strong water absorption and moisturizing function, and can also enhance the long-term water retention ability of skin, help elastic fibers and collagen to be in a moisture-filled environment, and make skin more elastic.
Hyaluronic acid with different molecular weights has different ability to penetrate the skin and different effects. The following table shows the different effects of hyaluronic acid with different molecular weights (large molecular weight, medium molecular weight and small molecular weight).
Efficacy of sodium hyaluronate in molecular weight range
The high molecular weight of 1 800 000 ~ 2 200 000 can prevent dehydration, regenerate tissue cells and tighten skin.
Medium molecular weight 1 000 000 ~ 1 800 000 tightens the skin and moisturizes it for a long time.
The small molecular weight of 400 000 ~ 1 000 000 quickly hydrates with cells, maintaining the cell's
Hyaluronic acid will gradually form a film rich in water in the stratum corneum, and transport water inward and outward at the same time. Therefore, when the environment is dry, it is necessary to rely on the sealing agent to reduce its outward water evaporation in order to maintain water for a long time. Sealants can form a thin film on the skin surface to prevent water from "losing". Sealants are usually greasy, such as vaseline, mineral oil and silicone derivatives.
Remove wrinkles
Because of age, smoking, squeezing during sleeping and the traction of gravity, the hyaluronic acid in the skin will be lost, and then the collagen and elastic fibers in the dermis will gradually decrease, resulting in skin relaxation and wrinkles on the face. Injection of hyaluronic acid can effectively solve all kinds of wrinkles:
1, hyaluronic acid beauty is suitable for frown lines (brow lines) and crow's feet lines.
For over-depressed frown lines, injection of botulinum toxin alone is often not satisfactory, and injection of hyaluronic acid will be better.
2, hyaluronic acid beauty is suitable for corners of the mouth.
Although the lines produced by pouting are dynamic lines, they will sag with hyaluronic acid.
Hyaluronic acid wrinkle removal
Line filling, good effect.
3. Hyaluronic acid beauty is suitable for tattoos (nasolabial groove)
Eliminating decree lines is the most commonly used purpose of hyaluronic acid wrinkle removal. According to the depth of wrinkle nose lines and the depth and position of wrinkles, it is generally necessary to inject polymers for about 2 times, including the lateral alar depression, the decree lines themselves and the lower lip.
4. Hyaluronic acid beauty is suitable for wrinkles around the mouth.
Including fine lines around the mouth, that is, dry lines around the lips caused by long-term water shortage; Including the mouth line, that is, the position where the mouth drools, some form a small bracket line, and some form a large bracket line (connected with the nasolabial groove).
Shape; appearance
Rhinoplasty: Although the development of rhinoplasty technology has reached a certain height, since hyaluronic acid injection was used for rhinoplasty, prosthetic rhinoplasty has been challenged because of its advantages of fast shaping, no surgery and no pain.
Dragon under the chin: the popular V-shaped face is easy to realize from the chin. It can also solve the problem of chin retraction.
Fill your face
People's aging will change the distribution of subcutaneous tissue, and the temporal area, cheeks, orbit, eyebrow arch and lips will all be sunken, and tears will also appear. Hyaluronic acid is used for facial filling, including lacrimal groove, decree pattern and puppet pattern (women's three "eight" patterns), which is very popular and has remarkable effect.
Lip augmentation: Generally speaking, people's lips will shrink and wrinkle with age, and the corners of their mouths will droop with age. Hyaluronic acid lip augmentation has been well received.
Fill dent
Hyaluronic acid can also be used to fill some pockmarked holes, trauma, scars caused by surgery, asymmetry of birth defects and so on.
