In modern medical cosmetology, hyaluronic acid fillers injection has become a pupular cosmetic treatment for many people, using hyaluronic acid filler to achieve lip augmentation, facial contour correction, breast augmentation and buttocks augmentation.
However, no matter how experienced the practitioner is, some side effects may still occur after completing the filler injection, the most common of which is bruising. Bruising is the most conspicuous side effect because it leaves purple and blue marks on the face, which will affect the patient's return to normal work and life.
Hyaluronic acid injections enhance the beauty and harmony of our face, but we must also be prepared to accept the temporary price they come with—bruising. How to cover bruises after filler injection?
Why do bruises occur?
Thousands of filler injections may cause more or fewer bruises each time, as the human face has complex and a large number of blood vessels, and even the most experienced practitioners cannot perfectly avoid puncturing blood vessels.
When hyaluronic acid filler is injected, the injection needle will pass through the skin and enter the subcutaneous tissue. During the process, the needle may touch these tiny blood vessels, causing them to rupture and bruise.
Postoperative bruises will not appear immediately. Bruise usually begins to appear within 24 hours after injection, that is, obvious bruises will appear on the second day. The initial color is red or purple. Over time, the color will gradually change to blue, green or yellow, and eventually fade away.
Although bruises themselves are temporary and will fade away within a week or two, for those seeking beauty, it may affect their appearance, so covering bruises is an issue worth discussing and solving.
Use blunt injection: effectively reduce bruises

Working principle of blunt injection needle
As the name suggests, the blunt injection needle is not as sharp as the traditional sharp needle, but is blunted with a rounded edge.
Sharp needles can easily puncture balloons, just like puncturing skin and blood vessels, while cannulas do not easily puncture skin and blood vessels. When cannulas pass through subcutaneous tissue, they cause minimal stimulation to surrounding blood vessels and nerves.
cannulas do not cut or puncture blood vessels like sharp needles do.
Instead, they avoid direct damage to blood vessels by pushing away blood vessels and tissues, thereby significantly reducing bruising and swelling after injection.
Reduce blood vessel damage and reduce the risk of bruising
Blood vessels are one of the root causes of bruising. When injecting hyaluronic acid filler, the needle can easily touch the blood vessels when it penetrates the skin, which may cause blood vessels to rupture and form bruises.
The sleek design of the blunt needle can avoid blood vessels and avoid blood vessel rupture. Therefore, blunt injection needles can greatly reduce the chance of bruising and make the postoperative recovery process smoother.
Improve postoperative swelling and discomfort
In addition to bruising, common side effects after injection include swelling and discomfort. When using a blunt needle for filler injection, the doctor can more accurately inject the filler into the target area, reduce damage to surrounding tissues, and make postoperative recovery smoother and avoid excessive swelling and discomfort.
How to choose a suitable blunt cannula?
Material and quality of microcannula
First of all, the material of cannula has a direct impact on reducing bruises.
For safety reasons, high-quality cannulas are usually made of high-quality stainless steel, because stainless steel has better toughness and can be bent at any angle without deformation during injection.
A microcannula with good material can smoothly slide through the skin and subcutaneous tissue to avoid damaging blood vessels.
Design and sharpness of needle tip
The design of cannulas should be characterized by smooth and round needle tip. As the blunt cannula does not need to perform the function of puncture, it only needs to be inserted into the puncture port and "push away" the blood vessels during the injection process.
Cannula diameter and length
Choosing a blunt cannula with appropriate length and diameter can ensure accurate control of the injection dose.
Most facial injections choose 25G cannulas for operation. For small-scale injections, such as under the eyes and around the eyes, a smaller diameter, such as 30G, is required to reduce the scope of trauma and reduce bruises.
How to Cover Bruises after Filler Injection?

Use concealer
Concealer is the most direct and effective method. Concealer has a strong covering power and can easily cover the bruises on the face. Choose a concealer with strong covering power to cover the color of the bruise.
For different stages of bruises, you can choose different colors of concealer: purple and blue bruises can choose yellow or orange concealer, while yellow bruises are suitable for concealer with pink or peach tones.
When applying, you can pat with a makeup brush or sponge to make the concealer evenly cover to achieve a good concealing effect.
Use cold and hot compresses
Cold and hot compresses are auxiliary methods to relieve bruises. In the first two days after injection, cold compresses can help constrict blood vessels and reduce the degree of bruises.
After the bruise gradually turns yellow, hot compresses can help speed up blood circulation and promote the disappearance of bruises.
But be careful not to confuse the time period of cold and hot compresses. If you use hot compresses in the first two days of bruises, it will speed up blood flow and make bruises more serious.
Avoid taking blood thinners
Blood thinners can cause bleeding in wounds and are not conducive to the healing of bruises, such as aspirin and ibuprofen. This is a very reasonable suggestion.
Take medication with caution during the bruise period, or take medication under the doctor's advice to avoid worsening the bruise.
Avoid touching the bruised area
During the recovery period after the filler injection, try to avoid touching the injection site. As the blood vessels during the bruise are already very fragile, friction or hard pressure may cause the bruise to become more severe and even prolong the recovery time.
Choose high-quality injection fillers to reduce the side effects of injection
Choosing high-quality injection products can effectively reduce the occurrence of side effects, including allergies, bruising and swelling.
As a top-level hyaluronic acid injection product, Diaminy dermal Filler has won the favor of many operating physicians for its unique formula and strict quality control.
1. Reduce allergic reactions and reduce skin irritation
Diaminy high-quality hyaluronic acid has high purity and biocompatibility, which greatly reduces the risk of allergic reactions during injection and is suitable for patients with skin allergies.
Low-quality hyaluronic acid may contain impurities, which may cause allergic symptoms such as skin redness, itching, and swelling, leading to discomfort after surgery.
2. Reduce the occurrence of bruises and swelling
Diaminy high-quality hyaluronic acid has good fluidity and flexibility during the injection process, allowing it to be evenly distributed in the injection area, avoiding swelling and bruising caused by uneven injection.
Low-quality hyaluronic acid filler often has a granular or piled-up appearance after injection due to its unstable molecular structure, resulting in uneven effects and even aggravating the degree of swelling and bruising.
3. Improve the naturalness and durability of the injection effect
Diaminy high-quality hyaluronic acid filler can accurately simulate the natural hyaluronic acid in the skin, and the effect after injection is more natural and lasting, producing a natural three-dimensional and plump effect.
Low-quality hyaluronic acid filler may have uneven or overly abrupt effects after injection, and even affect the harmonious beauty of the facial contour.
4. Reduce the risk of infection and complications

The production process of Diaminy hyaluronic acid filler is more rigorous, the sterile environment is strictly controlled, the product is safe and reliable, and the risk of infection during injection is reduced.
Low-quality hyaluronic acid may have problems such as lax environmental control and unstable ingredients during the production process, which can easily cause bacterial contamination and increase the chance of postoperative infection.
Conclusion
Although hyaluronic acid injection fillers can bring satisfactory cosmetic effects, postoperative bruising is a realistic problem that many people need to face. Through the correct covering method and care skills, the impact of bruising can be effectively alleviated, allowing you to restore your natural beauty in a short time.
At the same time, choosing high-quality injection fillers, such as Diaminy Dermal Filler, can reduce damage to blood vessels during injection, reduce the risk of bruising, and ensure that your beauty process is safer and more comfortable.
If you are considering hyaluronic acid injection, choosing Diaminy Dermal Filler is undoubtedly a sensible choice. It not only brings natural facial correction effects but also allows you to avoid unnecessary irritation and allergies, keeping beauty and health coexisting.
