When choosing a filler method, many friends are torn between autologous fat and hyaluronic acid and are indecisive. How exactly should these two be chosen? Today, we will give you a detailed explanation. Autologous fat As the name suggests, autologous fat is your own body fat, such as the waist, abdomen, thighs under the skin there is a rich “fat treasure”. Transplantation is to move the fat from one place to another, such as moving the fat from the thighs to the breasts and the fat from the waist and abdomen to the buttocks, so as to present a comprehensive effect of thin waist and buttocks, thin legs and big breasts. However, it has a disadvantage: the transplanted fat cannot survive 100%, and the larger the transplanted volume, the lower the chance of survival. Hyaluronic Acid Hyaluronic acid is a straight-chain polymer polysaccharide composed of disaccharide units, which is a naturally occurring substance in tissues. It is also found in the connective tissue and dermis of the body and is a clear gel-like substance. It was first used as a viscoelastic for ophthalmic IOL implantation, as a filler for joint surgery such as osteoarthritis and rheumatoid arthritis, and for post-operative adhesion prevention and skin wound healing. It was officially approved by the FDA in 2003 for skin wrinkle treatment (e.g., head lift) and in Asia for fine-tuning facial contours (e.g., nose job, apple muscle augmentation, lip and chin augmentation, etc.). Because of its ability to retain and lock water (it can combine more than 400 times its own water), it has also been gradually used in recent years for skin beauty treatments to keep the skin hydrated and replenished (such as hydrafacial injections). However, hyaluronic acid will also be absorbed by the body and needs to be replenished. The difference between the effects: 1. Which one has the strongest retention time? This is the primary problem that plagues many customers. First of all, autologous fat transplantation has a survival rate, which means that if you transplant 100 units of fat to another part, the final survival rate may be less than 60%, and you will need to suck the fat again and transplant it again. Hyaluronic acid, depending on the molecular weight of the injections you choose, the maintenance time varies from 6-12 months, and friends who want to sustain the effect also need to play. 2.Who is more cost-effective for the recovery period? If you are going to attend an important event in the near future, then at most one week in advance for hyaluronic acid injection filling is fine, and there are many customers who are injected 1-3 days before the event. If you are rich in time and have a lot of restoration time, then you can consider autologous fat transplantation. After body contouring, you need to wear shapewear for at least 3 months (to keep the skin of liposuction parts tight to avoid sagging), and the filled parts are puffy for at least 1 month after surgery, especially for facial filling, which means you have to leave yourself at least one month of recovery time. 3.Who has longer treatment time? Autologous fat transfer is necessary to see if your subcutaneous fat is abundant enough (not suitable for girls with thin body type), and then start the liposuction surgery, the amount of liposuction must be more than the estimated injection amount. Next, the healthy fat will be injected into the designated area through a syringe, which will take into account the doctor’s skills. Hyaluronic acid is particularly convenient and fast for the improvement of the five senses, forehead, temples, sleeper, apple muscle, fill tear trough, nose, chin and lips …… 1-2ml per part, 30 minutes to get it done! The effect is immediate. Girls can try regardless of fat or thin. 4.Who has higher risk of trauma? If you choose autologous fat transplantation treatment, the medical staff will first clarify you that this belongs to the category of surgery, that is, the need for anesthesia, incision, bleeding and recovery period, the need to abstain from some food such as spicy hot pot, seafood hair, while taking a week of oral antibiotics, etc., pay attention to the massage of the treatment site and post-operative maintenance, as well as regular return visits. Autologous fat surgery is safe ≠ no complications. The thickness of autologous fat breast augmentation should be 2~3mm to improve the survival rate. Hyaluronic acid, on the other hand, belongs to the category of micropigmentation. Make sure that you are healthy and have no contraindications to treatment in the preoperative case, then you can prepare for the treatment, just apply the surface anesthetic cream on the treatment area for 20-30 minutes, then you can start the treatment. 10 minutes of filling the treated area should not be squeezed and rubbed for 48 hours, for rhinoplasty, it is not recommended to wear frame glasses, and try to avoid smoking and drinking alcohol for 1 week after the operation. If the result of the treatment is not to your satisfaction, you can also get rid of it by injecting hyaluronic acid dissolving enzyme! What is the difference between injection sites? 1.Autologous fat transfer can do: breast augmentation, buttock augmentation, cheek augmentation, forehead augmentation, lip augmentation, nasolabial fold augmentation, apple muscle augmentation, temple augmentation, etc. 2.Hyaluronic acid filler can do: forehead augmentation, temple augmentation, tear trough augmentation, lip augmentation, nose augmentation, chin augmentation, apple muscle augmentation, nasolabial fold augmentation (decency lines), earlobe augmentation, head lift lines, interbrow lines, cheek augmentation, skin water retention improvement, fill in acne scars and pits, etc.
