Injection rhinoplasty is a non-surgical cosmetic treatment method that improves the shape of the nose by injecting filling materials. Compared with traditional surgical operations, injection rhinoplasty has the advantages of less trauma, quick recovery, and more natural results. Therefore, it is favored by many people seeking beauty. However, the duration of the effect of injection rhinoplasty varies depending on many factors, among which the type of injection material, injection site, patient's physical condition and other factors will affect the maintenance time. This article will discuss in detail the maintenance time, influencing factors and postoperative precautions of injection rhinoplasty.
1. Common materials and characteristics of injection rhinoplasty
The materials used for injection rhinoplasty are mainly divided into two categories: hyaluronic acid and autologous fat . In addition, there are some other materials such as expanded fillers and collagen , but hyaluronic acid and autologous fat are currently the most commonly used injection materials.
Hyaluronic acid
Hyaluronic acid is currently a filling material widely used in injectable rhinoplasty. It has become the mainstream choice because of its good biocompatibility and low risk of allergic reactions. After hyaluronic acid injection, it can provide three-dimensionality and fullness to the nose, but its effect is not permanent and is usually gradually absorbed by the human body between 6 months and 1 year.
autologous fat
Autologous fat injection rhinoplasty uses the patient's own fat tissue. After the fat is removed through liposuction surgery, it is carefully processed and injected into the nose. The advantage of autologous fat is that it avoids the rejection reaction that may be caused by foreign substances and is relatively natural. After autologous fat injection, part of the fat will be absorbed and the remaining part can be maintained for a long time. Generally speaking, the effect of autologous fat injection can last for 2 to 3 years, and in some cases it can be maintained for a long time.
Expanded fillers and collagen
Expanded polytetrafluoroethylene fillers and collagen are also sometimes used for rhinoplasty, but are used less frequently due to their higher risk of allergies and longer absorption time.
2. How long does the effect of injection rhinoplasty last?
The duration of the effect of injection rhinoplasty is affected by many factors, the most important of which is the selected injection material.
How long does hyaluronic acid last?
The effect of hyaluronic acid injection rhinoplasty usually lasts about 6 months to 1 year. The specific length of time depends on factors such as the type of hyaluronic acid used, the patient's metabolic rate, and the injection site. Hyaluronic acid will gradually be metabolized and absorbed by the human body over time, so regular supplementary injections are required.
High-concentration hyaluronic acid : Some high-concentration hyaluronic acid products have a longer duration. Some brands of hyaluronic acid can last for about 1 year, especially at the injection site on the bridge of the nose.
Low-concentration hyaluronic acid : Low-concentration hyaluronic acid is absorbed faster and the effect usually lasts about 6 months.
How long does autologous fat last?
The effect of autologous fat injection rhinoplasty is relatively long-lasting. Although part of the fat will be absorbed after injection, the remaining fat can continue to grow in the nose and fuse with the surrounding tissues. Therefore, the effect of autologous fat injection can usually last for 2 to 3 years, or even longer.
Fat absorption : After fat injection, about 30% to 50% of the fat may be absorbed, and the remaining fat can exist stably, forming a more lasting effect. Since autologous tissue is used, the probability of rejection reaction is low.
Durability of other filling materials
The effects of expanded polytetrafluoroethylene and collagen materials last longer. Expanded polytetrafluoroethylene fillers can generally last for 3 to 5 years, but due to the risk of displacement or infection, they need to be used with extreme caution. The effect of collagen is relatively short-lived, generally only lasting a few months.
3. Factors that affect the duration of injection rhinoplasty effects
In addition to the characteristics of the filler material used, several factors will affect how long the results of injectable rhinoplasty last, including the following:
Individual metabolism
Everyone's metabolic rate is different. People with faster metabolism may absorb the injected material faster, resulting in a shorter duration of the effect, while people with slower metabolism may maintain the effect longer. Overall, young people and people with healthy constitutions have slower metabolism, so the effect may last longer.
Injection site
The specific site of injection also affects the duration of effect. Generally speaking, the injection site of the bridge of the nose is relatively stable and the effect lasts longer; while the filling effect of the nose tip may be relatively short-lived, especially when using materials such as hyaluronic acid, because the blood circulation in the tip of the nose is relatively rich, which may accelerate the absorption of the injected material.
Injection technique
The doctor's injection skills and experience also affect the duration of the effect. A skilled doctor can reasonably arrange the injection levels and dosages, reduce the absorption rate of the material, and thus prolong the duration of the effect.
Postoperative Care
Postoperative care also plays an important role in maintaining the effect of injection rhinoplasty. Following the doctor's advice after the operation and avoiding strenuous facial activities and external force collisions can effectively reduce the risk of premature absorption of the injected material.
Brand and quality of materials
The quality of hyaluronic acid or fat filling materials from different brands varies. Some brands’ products may last longer due to their more stable molecular structure and stronger water retention. Choosing high-quality filling materials can effectively prolong the duration of the effect.
4. How to prolong the effect of injection rhinoplasty
Regular supplemental injections
If you want to maintain the rhinoplasty effect for a long time, it is recommended to have 1-2 injections per year. Especially for easily absorbed materials such as hyaluronic acid, regular supplementation can effectively maintain the shape of the nose.
Pay attention to postoperative care
After the operation, avoid excessive facial expressions and improper postures, reduce the absorption and loss of injected materials, avoid sun exposure, and avoid hot compresses and other improper operations that may irritate the injection site.
Healthy diet and daily routine
Maintaining good work and rest and eating habits and avoiding excessive intake of high-sugar and high-fat foods will help slow down the absorption process of the injected material.
Beauty Encyclopedia Tips:
The effect of injection rhinoplasty varies depending on the type of material and individual differences. The effect of hyaluronic acid usually lasts for 6 months to 1 year, while the effect of autologous fat can last for 2 to 3 years. In order to prolong the duration of the effect of injection rhinoplasty, patients should choose a professional doctor for the injection and follow the postoperative care instructions. Regular supplementary injections and maintaining a healthy lifestyle are also important means to prolong the effect.
