Botox and fillers are two common micro plastic surgery in beauty clinics and have become an important means for many people to pursue beauty and youth. Botox can improve fine wrinkles on the face and restore the firmness and smoothness of the skin. Fillers can not only improve facial wrinkles but also increase facial volume, optimize facial contours, make the face more three-dimensional, and make the face more harmonious.
However, despite the widespread use and remarkable results of these treatments, there are still some potential side effects of Botox and fillers. This article comprehensively explains the negative effects of these two operations.
Side Effects of Botox
Botox, as a neurotoxin, is often used to treat facial wrinkles and make the skin smooth. The mechanism of Botox injection is to temporarily paralyze the facial muscles through the toxin to reduce the formation of wrinkles. Since Botox itself is a toxin, unlike hyaluronic acid, hyaluronic acid fillers can be absorbed by the human body, and the injection process can also cause discomfort and swelling at the injection site.
One of the most common side effects of Botox injection is slight swelling or pain at the injection site. This condition is usually caused by a local reaction caused by the needle piercing the skin, and the patient may feel some discomfort. Fortunately, this discomfort usually subsides on its own within a few hours to a few days.
Headache
After Botox injection, some patients may experience a mild headache. The cause of the headache is usually related to the nerve reaction after the drug injection, mainly the body's allergic reaction to Botox, but this pain will subside within a few days after the operation.
Unnatural facial expression

The core function of Botox is to inhibit the formation of wrinkles by paralyzing facial muscles. This is Botox's advantage, but it can also have the opposite effect. If the injection is not done properly, it may cause the facial muscles to relax too much, resulting in a stiff or unnatural expression.
It is often heard or seen that some people will have a stiff expression after Botox injection, and they cannot express their expressions naturally when making expressions, showing a disordered facial expression.
Ptosis
Botox may cause ptosis of the eyelid, which is usually caused by the drug spreading to areas where it should not be injected, affecting the eye muscles. This side effect will aggravate the aging of the eyes, affect the patient's social life, and bring a certain amount of stress to the patient. This phenomenon often eases after a few weeks.
Allergic reaction
Although extremely rare, some individuals may have an allergic reaction to Botox. Common allergic reactions include redness, swelling, itching, or shortness of breath. For patients with a history of allergies, it is recommended to conduct an allergy test before injection to ensure its safety.
Swelling and tingling in the injection area
Post-injection swelling is usually caused by slight irritation of the needle and the toxin to the skin and surrounding tissues during the injection of Botox. When the injection needle pierces the skin, it may cause slight blood vessel damage due to the sharp needle used, resulting in mild local swelling. This swelling is generally most obvious within 24 hours after treatment and usually subsides on its own within a few days.
In addition, pain is another common discomfort reaction, which usually occurs on the day of injection. The degree of pain varies from individual to individual, but is usually mild to moderate.
Side Effects of Fillers Injection

Fillers are a medical beauty method that fills the gaps in the face through injection to improve wrinkles, sagging skin, or increase facial contours. Fillers include hyaluronic acid, collagen, poly-L-lactic acid, etc. They are increasingly used in the market, and the injection technology is becoming more and more sophisticated, but even the most mature injection operation will bring certain side effects to patients.
Redness, swelling, pain, and nodules at the injection site
Similar to Botox, the most common side effects after filler injection are redness, swelling, and pain at the injection site, but the injection of fillers will have an additional side effect of nodules. These reactions usually subside within a few days and are local reactions caused by the needle irritating the skin and tissues. Mild lumps are usually caused by the failure of the filler to be evenly distributed. As the quality problems of the filler or the operation method, lumps are produced after injection.
Filler Migration or Granulation
If the injected filler is not evenly distributed or is affected by external pressure, filler displacement or granulation may occur. Filler displacement can cause an unnatural appearance on the face because the filler in the original position has moved to another place. Granulated fillers may cause uneven skin and lumps, and even require injection of hyaluronic acid diluent enzymes to solve the problem.
Allergic reactions
Although most modern fillers (such as hyaluronic acid) are relatively safe, some patients may still have allergic reactions to certain filler materials. Allergic reactions can manifest as local redness, swelling, itching, or cause greater physical reactions. If you encounter this phenomenon, you should seek medical attention in time.
Infection
When injecting fillers, local infections may occur because the injection tools have not been sterilized or there are problems with the operating environment. Infections usually manifest as symptoms such as redness, swelling, heat, and suppuration in the injection area. Therefore, when using needles, the operating physician should purchase sterile needles or blunt cannulas to ensure a smooth operation process.
Diaminy aesthetics store provides sterile needles and cannulas to ensure the safety of the operation process, avoid infection, and give patients a pleasant injection experience.
Vascular occlusion
One of the more serious side effects is vascular occlusion, which may occur during the injection of fillers. If the filler enters the blood vessels, it may cause blood flow obstruction, resulting in local tissue necrosis, and even serious complications such as blindness. To avoid such situations, the physician needs to accurately locate the injection site and be familiar with the distribution of blood vessels on the face.
How to Reduce the Risk of Side Effects of Botox and Fillers
Although the side effects of Botox and fillers are usually mild and short-lived, consumers should be extremely cautious when choosing treatments to ensure safety and effectiveness. Here are some suggestions to reduce the side effects of botox and fillers:
Choose a professional physician and institution
Botox and filler injections require highly professional techniques, so it is crucial to choose a physician who has been formally trained and experienced. Formal and professional physicians not only have the corresponding techniques, but also have complete and safe operating tools to ensure the safety of the entire operation.
Use high-quality injection tools
Choosing high-quality sharp and blunt cannulas can ensure a more precise injection process, reduce tissue damage and unnecessary complications. Low-quality tools may result in rough needles, uneven drug injection, or the risk of infection.
Diaminy provides sharp and blunt cannulas for injecting botox and fillers for the operating physician to choose. The sharp needle has a sharp and smooth needle tip that can easily pierce the skin, and the blunt cannula has a smooth needle tip to avoid piercing blood vessels and protect the nerves under the skin.
Follow postoperative care instructions

After the injection, patients should strictly follow the doctor's postoperative care recommendations, such as avoiding massage of the injection site and avoiding strenuous exercise. Proper postoperative care helps speed up recovery and reduce side effects.
Pay attention to postoperative observation
If abnormal reactions occur after the injection, such as persistent swelling, severe pain, blurred vision, etc., you should seek medical attention immediately. Timely detection and treatment of problems can effectively avoid the occurrence of complications.
