Is there a risk of blindness?
If a cannula is used, the story changes
There are many people who are curious about nose fillers,
so I organized everything myself, one by one.
"Doesn’t the nose spread out or look wider?"
"Is there really a risk of necrosis or blindness?"
"How is it different from surgery?"
I get these questions very often.
I’ll answer each one honestly.
✅ 1. What kinds of side effects can nose fillers cause?

The most serious side effect of a nose filler is
nose necrosis that can occur
when a needle is used.
If the filler is injected with a needle,
there is a risk it can enter a blood vessel,
and if the vessel becomes blocked,
the tissue can undergo necrosis.
That is why nose filler
must be performed with a cannula.
Because the cannula has a blunt tip,
it is difficult for it to pierce directly into a blood vessel,
which can greatly reduce this risk.
Also, if the skin has weak elasticity,
a thread lift should be considered along with the filler instead.
If the skin support is insufficient,
it is difficult for the filler to stay in place.
✅ 2. Can it spread out or look wider?

Yes, that can happen if the wrong filler is used.
If a soft filler is used,
the pressure from above can cause it to spread sideways.
For nose filler, you should always use a very firm filler,
such as Restylane LYFT.
That is because a firm filler
can withstand the pressure of the nose skin
and maintain its shape.
If you understand the properties and characteristics of the filler correctly,
you will always choose a firm filler for the nose.
If the nose is very firm,
using threads rather than filler is
much more effective.
In such cases, filler is used only as a supplement.
✅ 3. How long does it last?

With regular filler, after one year
about 50% is absorbed.
A firm filler like Restylane LYFT
is absorbed only about 40%
even after one year.
In other words, it lasts longer.
Areas with little movement, like the nose,
have better longevity than other areas.
The timing of a touch-up varies from person to person,
but it is decided after checking the condition after one year.
✅ 4. How much does it cost?

Based on imported fillers,
it is around 300,000 to 500,000 KRW.
If a domestic filler is used,
it is usually around 200,000 KRW.
There is a price difference depending on
which filler is used,
and the reason a firm imported filler is recommended for the nose
is the difference in the quality of the result.
✅ 5. What is the difference between nose surgery and nose filler?

Nose surgery uses hard, firm materials
such as implants or cartilage.
It is a method that changes the structure itself.
Nose filler adds volume with a substance
that is weaker than cartilage.
It is difficult to achieve the same structural change as surgery,
but a natural height increase
and line improvement are definitely possible.
It has much less anesthesia, recovery, and cost burden,
and the biggest advantage of filler is that
it can be dissolved if you are unhappy with it.
✅ 6. Is there really a risk of blindness? How can it be prevented?

Yes.
That is why this is the most important part.
If nose filler is performed with a needle,
intravascular injection can occur,
and if the blood vessels in the nose become blocked,
it can connect to the vessels around the eyes
and lead to blindness.
There is only one way to prevent it.
Use a cannula.
By using a cannula,
you are free from the risk of intra-arterial injection.
If you are considering nose filler,
make sure to check whether the procedure is done with a cannula.
✅ 7. Can it be done naturally without looking obvious?

Yes, it can.
Because the goal of the procedure is always
set in a natural direction,
it is performed to the point where others would have trouble noticing.
The core of nose filler is
creating a more three-dimensional change in the face
without it being obvious.
✅ 8. Can it be dissolved right away if I don’t like it?

Yes, it can be dissolved at any time.
Hyaluronic acid-based fillers
can be broken down with hyaluronidase.
Even if you are not happy with the result
or need adjustments,
it is possible to correct it,
which is a major advantage of filler.
✅ 9. How is anesthesia done? What about pain?

Point anesthesia is administered by injection.
It is a method that anesthetizes only the necessary area
with minimal treatment.
If done slowly,
the pain is not severe,
so for most people it is at a level that can be tolerated.
✅ 10. Which area is most important during the procedure?

Two areas are focused on.
First, the middle bony part of the bridge.
This is the area that is most often low,
and if you raise it,
the entire bridge comes to life.
Second, the base of the columella.
If this area is low,
the tip of the nose looks low,
so if it is corrected here,
the tip of the nose can naturally appear lifted.
The design focuses on these two points:
the bridge and the tip that lift well.
✅ 11. Are there cases where nose filler is not suitable?
If the skin is too firm,
it is not suitable.
If the skin lacks elasticity or is thick,
the filler may have trouble settling in place,
and the desired shape may not be achieved.
In such cases, threads or other methods
are considered together.
During consultation, the skin condition is assessed first,
and then the appropriate method is recommended.
For nose filler,
whether it is performed with a cannula,
which filler is used,
and whether a method suited to the skin condition is chosen
these three things determine the result and safety.
With a well-designed nose filler,
the entire face can change in a more three-dimensional way.
