Hyaluronic acid is a substance that the human body possesses to help moisturize the skin and lubricate the joints, and plays an important role as a matrix in the dermis of the skin. However, as time passes, the body’s hyaluronic acid content gradually decreases and skin moisture decreases, resulting in wrinkles and dry skin. Through artificial replenishment, the lost hyaluronic acid can be recharged to fill wrinkles naturally or achieve localized padding. Pure hyaluronic acid is not immunogenic and will be gradually absorbed by the body. Features of hyaluronic acid 1. Immediate effect. After the doctor’s injection and treatment, you can see the obvious effect immediately. 2.Natural effect. After hyaluronic acid injection, there is no obvious trace on the face, the effect is natural, people only feel that you have become beautiful, but can not see where it is changed, the beauty does not leave a flaw. 3.Safety is guaranteed. Hyaluronic acid is originally one of the dermal tissues of the human body, which has a short stay in the body and will be decomposed by the body after a certain period of time, so there will be no long-term side effects. 4.No recovery period is needed. The operation time is short, no need to be hospitalized, and it does not affect work and life. 5.The role is comprehensive. The most powerful function of hyaluronic acid is to remove wrinkles, the effect is very significant, and it can also be used for moisturizing and shaping. 6, any age is applicable, the effect is especially obvious for people over 40 years old. 7.The procedure is non-invasive and painless, easy and simple. The effect of hyaluronic acid – high-quality materials and plastic surgeons are indispensable The water content of healthy skin should be maintained at about 15% to 20%, and the water retention value of hyaluronic acid is very high – 1 gram of hyaluronic acid can absorb 500 ml of water, which is equivalent to glycerin It is recognized as the best moisturizing product in the literature today because of its 500 times water absorption capacity. Hyaluronic acid, which is included as a microplastic material, can be injected as a filler into the wrinkles and depressions of the dermis, or into areas that are desired to be plumped up, making the skin look full, plump and elastic, and achieving the effect of removing wrinkles and refining the face. Different brands of hyaluronic acid will produce different results because the molecular size of each brand varies slightly. In general, hyaluronic acid with relatively large molecules is absorbed a little slower than hyaluronic acid with smaller molecules, but an injection can maintain the effect for 6 to 12 months, and if supplemented with an injection, it can be maintained for up to 19 months. Of course, the absorption rate of the human body is also very much related to the location, for example, the lips are absorbed very quickly and the effect will be lost in half a year, while the nasolabial folds, perioral wrinkles, depression filling, etc. can be maintained for 9 to 12 months with a single injection. However, it should be reminded that the effect of injection is not only related to the material itself, but also closely related to the professional skill level of the plastic surgeon, one cannot be without the other. Who can consider hyaluronic acid injection? 1, people who want to eliminate facial wrinkles: Hyaluronic acid can be used to fill the forehead horizontal lines, crow’s feet, perioral wrinkles, interbrow lines, nasolabial folds; 2, people who want to locally adjust the facial contour in a small scale: Hyaluronic acid can be used for cheek augmentation, chin augmentation, temporal augmentation, forehead augmentation, nose augmentation, nose tip correction; 3, filling of depressed scar: people who have acne scar and other soft scar can consider hyaluronic acid injection; 4, lip augmentation. Generally speaking, human lips will shrink with age and wrinkles will appear, and the corners of the mouth will also sag due to aging, and hyaluronic acid filling for lip augmentation has gained a certain amount of praise. What is collagen? Collagen is the largest constituent of human dermal tissue and is closely related to skin aging. Injected collagen is gradually broken down by collagenase in the body, so it will not be filled permanently and the filling effect will gradually decrease over time. The retention time in the body is related to the volume injected, the injection site and the size of individual skin mechanical pressure. In addition, different collagen products and different body types also have a great influence on the retention time of collagen. The characteristics of collagen 1, repair and regeneration. Collagen injections can stimulate the dermal fibroblasts to produce new collagen and form new tissue, resulting in repair and regeneration. 2. Longer lasting effect. Compared to hyaluronic acid, the effect of collagen lasts longer, and the high-intensity spiral collagen can last even more than 12 to 18 months. 3.Safe and reliable. Collagen is currently the most widely used biomedical material, with a high degree of safety and biocompatibility, can be naturally absorbed by the skin tissue completely degraded, free to fuse between the cells. It has been clinically applied to the human body for more than 30 years and is the safest biomaterial in the field of biomedicine. 4.Multi-effect cosmetic effect. Collagen implant has the effect of filling depressions, eliminating wrinkles and improving local shape, so it is known as an all-round and multi-functional medical cosmetic agent in the field of beauty. 5.Fast recovery process. Collagen injection treatment generally does not affect normal work and life, some patients need to take a day off. The effect of collagen – all-round solution to skin problems Collagen contains hydrophilic natural moisturizing factor, and the triple helix structure can strongly lock moisture, which can keep the skin moist and hydrated at all times after injection. Activated collagen is highly permeable to the skin and can bind to skin epithelial cells through the stratum corneum to participate in and improve the metabolism of skin cells, resulting in enhanced collagen activity in the skin. It can maintain the moisture of the stratum corneum and the integrity of the fibrous structure, improve the living environment of skin cells and promote the metabolism of skin tissues, enhance blood circulation, and achieve the purpose of moisturizing the skin. The luster of the skin depends on the water content, and the good water retention ability of collagen makes the skin hydrated and shiny, which will emit a healthy glow. When collagen is absorbed by the skin, it fills in between the dermis of the skin, increasing skin tightness, producing skin tension, reducing pores, and making the skin taut and elastic. In addition, there is the most important point – anti-wrinkle, which should be the most familiar part of collagen efficacy. The plump collagen layer in the dermis holds up the skin cells, combining moisturizing and wrinkle inhibiting effects, together to stretch coarse lines and lighten fine lines. Collagen injection maintenance time Depending on the type of collagen product, some need only a full amount of injection to achieve the desired effect, while some need an over-injection of 100% to 150% or 150% to 200%, the effect of one injection can be maintained for an average of 6 to 12 months, and high-intensity collagen can even be maintained for more than 12 to 18 months. Supplemental injections can be given after 6 months of injection to effectively extend the retention time in the body. The overall duration of the effect depends on the application technique, implantation depth, implantation site, as well as the age and lifestyle of the patient. Who can consider collagen injection? 1, face and neck wrinkles: collagen injection can effectively improve tear troughs, nasolabial folds, crow’s feet, interbrow lines and other wrinkles around the eyes, so that the appearance is significantly younger, but it should be noted that different parts of the body should be injected with different collagen products. 2.People with lip augmentation needs: In most cases, the volume, position and texture of the mouth and lips can be improved by filling collagen. 3.Filling scar: anatomically speaking, the scar filled by collagen injection should be a shallow depressed scar, about 1 to 2 mm deep and 2 to 4 mm wide. Those who have a history of keloid scars should use collagen injection with caution. Theoretically, the collagen injected into the body will be involved in the formation of new keloid scars. The effect of collagen on the correction of keloid scars is temporary, and multiple injections are required to obtain satisfactory correction results.
