What is hyaluronic acid? Hyaluronic acid is also known as hyaluronic acid, the presence of hyaluronic acid in the human body, has the function of lubricating joints, as well as skin moisturizing, the skin also contains a large amount of hyaluronic acid. Human skin maturation and aging process also changes with the content and metabolism of hyaluronic acid, which can improve skin nutrient metabolism, make skin soft, smooth, increase elasticity, prevent aging, and be a good transdermal absorption promoter while moisturizing. Small molecules of hyaluronic acid can be used for hydration; medium and large molecules of hyaluronic acid are used in clinical practice to fill depressions or adjust facial contours. Let’s learn about the four major effects of hyaluronic acid 1. Hyaluronic acid can remove facial wrinkles such as forehead lines, frown lines, crow’s feet, lower eyelid lines, corners of the mouth, neck lines, etc. It is especially effective for nasolabial folds which are not easily solved by other treatments, and the surprising effect can be seen after injection. 2.Shaping It can solve the problem of nose augmentation, lip augmentation, chin augmentation, earlobe augmentation non-invasively… Hyaluronic acid shaping is a new method to perfect facial contour, which can be used for nose augmentation, chin augmentation, lip augmentation, etc. Because it does not require any incision, and the effect is fast and safe. 3.Smoothing facial depressions Plumping up temporal area, cheeks, cheekbones and temples Smoothing out depressed scars To make cheeks plump, hyaluronic acid injection filling has become the first choice of medical experts and gradually replaced silicone filling method. Hyaluronic acid can be used to fill in cheeks, temples, brow bones, sunken eye sockets, and restore depressed scars, which can achieve immediate effect of changing the appearance. 4.Moisturizing Long-lasting moisturizing, easily locking skin moisture The moisturizing effect of hyaluronic acid is 16 times that of collagen, which can not only lock the moisture in the skin, but also catch the water molecules in the external environment, continuously keeping the skin moist, maintaining the skin hydrated and firm, and preventing the skin from sagging and wrinkles. What are the advantages of hyaluronic acid filler? 1.No need to undergo the pain of taking fat from other parts of the body, just inject the filler directly; 2.Usually no blood test is needed before injection, no need to be hospitalized, only local topical anesthetic and then injection is needed; 3.The injection process usually takes only a few minutes, and the recovery time takes about 2-3 days to reduce swelling. If the amount of single injection is large, there will be mild edema, which will subside in about 3 days. What is the difference between large, medium and small molecules of hyaluronic acid? 1.Large molecule hyaluronic acid Large molecule hyaluronic acid has the hardest texture, the longest maintenance time, and is suitable for shaping, mainly used in shaping surgery such as breast augmentation and buttock augmentation, nose augmentation and chin augmentation, and the filling site is deep tissue. Hyaluronic acid can also be used to remove wrinkles. Hyaluronic acid is injected in the form of filler into the depressed dermal folds or areas that want to be plumped up, such as lips, cheeks, chin, etc. The effect of using large molecule hyaluronic acid to remove wrinkles can be maintained for a relatively long time. 2.Medium molecule hyaluronic acid Medium molecule hyaluronic acid is generally slightly soft in texture, suitable for soft tissue filling and certain filling and wrinkle removal; the injection site is usually the tear trough, lips and wrinkles, but like large molecule hyaluronic acid, the site of medium molecule hyaluronic acid injection is also deep tissue and cannot fill the surface layer of the skin. 3.Small molecule hyaluronic acid is a water-like hyaluronic acid molecule, which is generally used for fine sculpting and wrinkle removal, and is mainly injected into the dermis of the whole face to replenish the missing water in the dermis and repair damaged skin, so as to moisturize and rejuvenate the skin and make up for the shortage of large and medium molecule hyaluronic acid. Precautions after hyaluronic acid injection 1. Do not touch the injection area for at least 6 hours after the injection, do not use cosmetics and other irritating items for 24 hours after the injection, and do not get wet. 2.After injection, please keep your face relaxed and do not make too much facial expression. 3.No spicy food and seafood within one week after injection, light food is the main food. 4.No smoking or alcohol within one week after injection. 5.Aspirin or other similar drugs should not be taken by the patient after the operation, such drugs are to reduce the coagulation function of platelets, which is not conducive to the recovery of the injection site. 6.After hyaluronic acid injection, there will be slight redness, swelling and itching, because of the different body types, the degree of appearance is not the same, but this phenomenon will disappear soon, do not worry. 7.Please avoid extremely hot (sauna) or cold places before the swelling and redness are eliminated at the early stage of injection, as these are not conducive to the recovery of the injection site. 8.After hyaluronic acid injection, try to avoid hot springs, steam sauna and other such places.
