Will hyaluronic acid injections in the forehead cause lumps?
While hyaluronic acid injections in the forehead offer many benefits, some online reviews mention that "the forehead became lumpy after the procedure."
Looking into it, there seem to be quite a few reviews complaining about malfunctions, so many people must be feeling uneasy.
While hyaluronic acid injections are relatively easy to undergo, the quality of the results is significantly influenced by the skill of the treating physician.
The forehead, in particular, is a challenging area due to its thin fat layer, requiring a higher level of skill.
In some cases, when inexperienced doctors perform the procedure, unnatural bumps or curves may result.
Why injecting hyaluronic acid into your forehead causes lumps and bumps
Even if bumps appear on your forehead after the procedure, it doesn't necessarily mean it was a failure.
The following reasons may explain why hyaluronic acid injections cause a bumpy forehead.
It was not injected thinly and evenly.
One key point for achieving a smooth and beautiful result with forehead hyaluronic acid injections is to inject the absolute minimum amount thinly and evenly while considering the overall balance.
If too much is injected into a specific area, the hyaluronic acid that isn't absorbed by the body can form lumps.
Hyaluronic acid injections in the forehead require a high level of technical skill.
The injection volume was not appropriate.
Hyaluronic acid injections are,The appropriate injection volume varies depending on the body part.
In the case of the forehead, if the injection volume is too small, it may not spread evenly, making it prone to creating unnatural bumps and unevenness.
On the other hand, if there is too much, only one part will bulge out, preventing a clean line from forming.
Hyaluronic acid products are not suitable for the forehead.
Hyaluronic acid formulations come in various types, differing in firmness, duration, and ease of blending.
ThereforeIt is important to use the appropriate product for each specific area.。
Injecting hyaluronic acid formulations unsuitable for the forehead may result in poor integration and unnatural lumpiness.
The injected skin layer is shallow
The forehead has a thin layer of subcutaneous fat, and immediately beneath it lies the skull.
Therefore, injecting a large amount into the shallow layers of the skin is likely to make the bumpy texture more noticeable.
However, even if the formulation is delivered to deeper layers,In some cases, differences in muscle thickness can create unnatural gaps.。
Therefore,It is important to identify the layer to be injected and perform the procedure accordingly.。
People with naturally thin skin should take special care.
The muscles on the forehead and between the eyebrows move, changing shape.
Hyaluronic acid gradually changes shape over time after the procedure.
Of course, as hyaluronic acid is absorbed into the body, the volume gradually decreases, but that's not all.
The forehead and brow muscles can cause lumpiness. This is less likely to occur when injected into the deeper layers of the skin, butIndividuals with more pronounced muscle movement tend to show a noticeable lumpy texture.
The hyaluronic acid hasn't fully absorbed yet.
It takes time for hyaluronic acid to fully absorb.
Additionally, areas that bleed during treatment may develop hematomas, or swelling may occur where the needle was inserted, leading to unevenness.
As time passes and the hyaluronic acid filler settles into your forehead, it will become less noticeable in most cases.

After receiving hyaluronic acid injections, if you notice bumps on your forehead, it's important not to panic.
Wait until the hyaluronic acid filler settles into your forehead.
Although individual results may vary, it typically takes about one to two weeks for the injected hyaluronic acid to fully integrate with the surrounding tissue.
The hematoma will become less noticeable as the swelling subsides, and the edema will disappear within about two days.
In most cases, the bumpy texture tends to become less noticeable after about a month.
Even if a bump appears on your forehead, don't panic—wait a few days to see how it develops.
Refrain from strong stimulation or massage
Avoid rubbing or massaging your forehead too hard just because you're concerned about its bumpiness.
Many cosmetic clinics, including Bianca Clinic, do not recommend massaging the area immediately after hyaluronic acid injections.
Massaging your forehead too vigorously after hyaluronic acid injections can cause the hyaluronic acid to shift unnaturally or be absorbed into the body more quickly.
It is safer to refrain from strong stimulation or massage based on your own judgment.
Adding additional hyaluronic acid injections
If you've waited for the hyaluronic acid filler to settle but are still concerned about unevenness, another option is to have additional hyaluronic acid filler injected to smooth out the bumps and lumps.
However, achieving a balanced forehead contour while considering the existing hyaluronic acid already injected requires advanced technical skill.
Choose a doctor with extensive experience in hyaluronic acid injections.
Get Botox injections
For those who notice a noticeable bumpy texture when moving their forehead, combining Botox injections can be effective in some cases.
Botox injections suppress excessive movement of the muscles in the forehead and between the eyebrows.
Dissolve the injected hyaluronic acid
To correct hyaluronic acid injections, hyaluronidase (an enzyme that breaks down hyaluronic acid) can be injected to dissolve the product at the treatment site.
After an additional 72 hours have passed, re-injection is also possible.
This method is suitable when you want to make adjustments not only to the bumpiness but also to the overall balance and design.
