Most hyaluronic acid stays at a well-known stage. Even doctors usually only know about fruits. The rest is not well understood, although hyaluronic acid can be obtained from different biological structures, bacteria and other methods. However, if the human body is the same, the production is large, and the stability is high, the hyaluronic acid industry will be broken. It has extraordinary hygroscopicity, can reach 1000 times of its own quality, and has a wide range of applications: injection into bone joints. Relieve joint pain; It is used to relieve dry eye disease in both eyes; Promotional therapy as a drug vector; skin care products; Shaping filler. Hyaluronic acid obviously subsides in the remarkable changes of aging skin, and fine lines are closely related to dryness. The baby's skin contains hyaluronic acid 20 times higher than that of adults, so the baby's skin looks very smooth.
Attention to hyaluronic acid
As we all know, hyaluronic acid is a must for stars. But do you really understand? Why is the maintenance time different after injection? After the injection of hyaluronic acid, just pay attention not to do the following things, and the maintenance time is relatively long. The following are the precautions for hyaluronic acid injection.
1. Do not apply hot compress after hyaluronic acid injection
After hyaluronic acid injection, many people cannot use hot compress to remove redness or swelling on their faces. Although hot compress can promote facial metabolism, it will interfere with the function and characteristics of hyaluronic acid, so hot compress cannot be performed after hyaluronic acid injection.
2. Do not apply ice after hyaluronic acid injection
Many people think that ice compress can reduce swelling, so they can think of using ice compress to reduce swelling as long as there is swelling. In fact, there is nothing wrong with ice compress to reduce swelling, but it is not suitable for ice compress in some special circumstances. When ice compress is used to reduce swelling, hyaluronic acid is also dissolved, resulting in fruitlessness. Therefore, the swelling after hyaluronic acid nasal augmentation should not be immediately detumescent, but should be iced 30 days later, which is conducive to the shaping and fruit presentation after hyaluronic acid filling.
3. Keep your body straight within 4 hours after hyaluronic acid injection
Since hyaluronic acid needs to be combined with the body for a corresponding time after injection into the body, keep the body straight within 4 hours after injection of hyaluronic acid to prevent hyaluronic acid from deviating from other parts.
4. Prevent makeup within 24 hours after injection
Within 24 hours after the injection of hyaluronic acid, experts should be prevented from touching the wound after the injection of hyaluronic acid, let alone cleaning and makeup, to prevent the injection of hyaluronic acid into the eye of the needle from being eroded by bacteria and viruses, resulting in seven feelings in the eye of the needle.
5. Prevent facial massage within 7 days after injection
After hyaluronic acid is injected into the body, * initially brings plastic fruit, so within 7 days after hyaluronic acid injection, avoid facial massage to prevent hyaluronic acid from flowing out.
Hyaluronic acid and ecological hyaluronic acid for injection filling
Hyaluronic acid is a kind of glycogen with water absorption ability. Some swelling after injection is reflected in medicine. Therefore, during hyaluronic acid injection, it is usually necessary to predict the aesthetic interference of swelling on some parts, such as lacrimal groove and upper eyelid injection. Because some skin is very weak, only 67 points are filled to avoid the unnatural caused by excessive swelling. On the other hand, the jaw (jaw), temple (temple) and other parts of the "swollen" just want to "fruit", so it can be filled to saturation.
Different hyaluronic acid products have different swelling levels, and some of them have low swelling index, which is suitable for filling lacrimal groove, lip and other parts; Part of the swelling index is high, suitable for filling the chin, orbitozygomatic area (zygomatic arch) and other parts. The key factors affecting swelling index include hyaluronic acid content, production process, physical characteristics, and details of doctors' actual operation. Ecological hyaluronic acid itself is soft and has a short storage time (skin decomposition period is about 14-22 hours), so it is not filled with molded fruit and needs manual modification.
The essence of the so-called modification is to establish more connections between molecules through physical and chemical methods, so as to make hyaluronic acid more stable, increase the maintenance time in the body and shape the fruit to meet the requirements of filler. Modification process is the core factor affecting product quality, and different manufacturers have great differences.
How long can it last?
The duration of hyaluronic acid filling is related to many reasons. In addition to the product itself, the injection location also has a great impact. Generally, the maintenance time of hyaluronic acid will be reduced due to the large activity of injection site, lack of defense structure, first injection and other reasons. For example, about 3-4 months for lips and around the mouth; Nasal groove 4-6 months; 6 to 8 months in temple and orbitozygomatic region; Lacrimal groove, upper eyelid collapse for 8-12 months, etc.
Naturally, due to the differences in lifestyle, human metabolism, injection method and basic conditions, the maintenance time at the same location will be very different, which cannot be compared simply.
What is the difference between "large, medium and small molecule hyaluronic acid"?
After modification, hyaluronic acid can be deepened into product types with different physical characteristics, such as the heard "small, medium and biological macromolecule hyaluronic acid" to meet different facial filling requirements. In fact, the name "hyaluronic acid of small, medium and large biomolecules" is not strict. The description is "hyaluronic acid of small, medium and large particles". More accurately, the three components are not different, but the particle sizes of particles are different, like sugar, white granulated sugar and rock sugar.
Generally, the larger the hyaluronic acid particles, the stronger the shaping effect, the longer the holding time, and the deeper the injection level. Small particles of hyaluronic acid can be injected into the skin (injected with water) to alleviate shallow wrinkles; Medium particle hyaluronic acid is used to fill the wrinkles of subcutaneous tissue or part of lipid deficiency (nasal groove, lacrimal groove, etc.); Large particles of hyaluronic acid are used to shape the nose and chin. Therefore, different products should be selected according to different beauty requirements. In China, most hyaluronic acids are registered to improve the moderate nasolabial sulcus.
Hyaluronic acid filling and autologous fat filling
These two methods are both feasible methods for filling therapy, and each has its own advantages. Hyaluronic acid minimally invasive technology basically has no recovery time, the filling effect is highly accurate and controllable, suitable for small-scale facial decoration and filling, and the time is not loose. Fat transplantation has a large injection volume, which requires surgical absorption of lipid and corresponding recovery time. It is mainly used for the whole filling treatment of frontotemporal, cheek, etc., with sufficient recovery time.
