Shurink Side Effects: The 3 Most Common Ones We See in the Clinic and Recovery Time

If you’ve searched for Shrink side effects, you’re probably concerned about nerve pain, paralysis, or facial hollowness. Just by getting the depth selection right, you can avoid 90% of them.

Shurink side effects, the 3 most commonly seen

in the clinic and how long recovery takes



Please check this before reading


Q. Are Shurink side effects

a problem with the machine itself?

A. In most cases, it is not the machine,

but a mistake in choosing the depth.


Q. How long does recovery from side effects usually take?

A. Bruising and swelling: 3 to 7 days,

nerve irritation: 1 to 2 months at the longest.



Bottom line.

Most Shurink side effects

come from choosing the wrong depth.


The key difference.

Whether the tips for each area (1.5, 3.0, 4.5 mm)

were switched appropriately or not.


What we’ll cover today.

Which side effects are common,

and how many days it takes to recover.

Shurink side effects,

which ones are the most common?

In order of frequency: bruising and swelling,

temporary pain, and rarely, nerve irritation.


If you searched for "Shurink side effects" and came here,

most of you have probably already booked the procedure, or

noticed something unusual after treatment and

came to check what it could be.


These days, if you read all kinds of reviews,

you’ll see scary comments like "I felt numb," "my jaw hollowed out,"

and "the neuralgia lasted for a month."

Those stories can sound alarming.


But here’s the tricky part:

most of these side effects are not caused by a faulty machine,

but by the practitioner choosing the wrong depth.



Shurink is a HIFU procedure that uses tips in three depths:

1.5 mm, 3.0 mm, and 4.5 mm,

switched according to the treatment area.



The superficial dermis (1.5) targets skin texture refinement,

the subcutaneous fat layer (3.0) targets volume refinement,

and the SMAS layer (4.5) targets lifting.



If you use only one type of tip and treat the entire face,

side effects are almost guaranteed.







Why Shurink side effects

come from depth selection

If you fire 4.5 mm in an area with a thin jawbone,

it can reach the nerve.





Dr. Wi Young-jin’s key insight

Most Shurink side effects

come from choosing the wrong depth



If 4.5 mm is fired as is along a thin jawline,

nerve pain or temporary paralysis can occur.



Changing tips by area is the key to preventing side effects.





This is the most important part of this article.



As you move inward along the jawline, there are areas where

branches of the mandibular nerve run more superficially.



The coagulation point of the 4.5 mm tip is,

as the name suggests, at a depth of 4.5 mm.



But for people with a thin jawbone, the distance from skin to bone can

be less than 3 mm.



If you fire 4.5 mm in this condition,

the coagulation point may hit the bone or

stimulate the nerve pathway above it.



That is why, immediately after the procedure or within a few days,

one side of the mouth may not lift properly,

or water may leak out when brushing your teeth.



Pain is the same. When people say, "

Shurink hurts too much,"

many cases involve forcing 4.5 mm into areas

that do not actually need the SMAS layer.



When the coagulation points are created over muscle,

it can feel sore later when that muscle moves.



This is not something that numbing cream can easily hide.



That is why, at our clinic, we first check the thickness of the

skin, fat, and SMAS with ultrasound before treatment,

and use different tips by area.



For areas close to the jawbone, we remove the 4.5 mm tip

and replace it with 3.0 mm.



Honestly, I didn’t notice this pattern at first either.

Last month, a case involving a 49-year-old patient left a strong impression on me.

She came in after treatment at another clinic,

saying one side around her mouth felt awkward for a month, and

that she had come in "just for an evaluation, with no expectations."

She said she had no real expectations and simply wanted a diagnosis.


On ultrasound,

the jawline skin was thinner than average,

and there were signs that 4.5 mm had been used along that line in the prior treatment.



We postponed retreatment for the time being

and recommended medication and time for nerve recovery.



When she returned 3 weeks later,

the asymmetry had almost completely resolved, even to her surprise,

and she said she never expected it to come back this quickly.



When nerve irritation is relieved, recovery is usually

normal within 1 to 2 months.




Dr. Wi Young-jin’s key summary

Shurink side effects are not caused by "too many shots,"

but by "going in at the wrong depth."



Before treatment, ask how the tips will be

divided by area.



If the answer is "we’ll use 4.5 mm for the whole face,"

you should think twice right there.






Shurink value for cost, side effects

Where should I get it if I want to avoid them?

First check whether ultrasound diagnosis

and tip switching are being done, rather than the lowest price.



People talk a lot about value for money,

and ads like 600 shots for around 200,000 KRW are tempting.



But even with the same 600 shots,

a clinic that uses only 4.5 mm for everything

and a clinic that uses 1.5, 3.0, and 4.5 mm by area

are completely different treatments.



The former raises the risk of side effects,

while the latter achieves the same effect more safely

with the same number of shots.



So the real value for money should be judged as

the cost of receiving treatment without injury.



For those who are very afraid of pain, numbing cream alone

is often not enough to tolerate 4.5 mm.



In that case, an additional nerve block solution or

sedation anesthesia can be used together.



However, sedation adds extra cost, so

please confirm in advance.

The case of a 43-year-old patient is a good example.



On the first treatment, the pain was so severe at another clinic

that she had to stop midway and came to us.

After checking the thickness with ultrasound, dividing the tips by area,

and adding a nerve block solution,

she said, "Is this really the same procedure?"



In the end, value for money comes down to

whether it was tailored to my face.






3 frequently asked questions about Shurink side effects



Q1. A few days after getting Shurink,

one corner of my mouth feels a bit awkward.

Is this permanent?

A. If I don’t address this,

you’ll regret it, so I’ll answer clearly.



Statistically, nerve irritation is reported in less than 0.1%,

but in the clinic, we still see one or two cases a month.



Most recover naturally within 1 to 2 months.



If it’s within 2 weeks after the procedure, please wait first,

and if it continues for more than a month, be sure to let the clinic know

so the progress can be followed.



Permanent paralysis is truly rare.



Q2. To prevent Shurink side effects,

what should I check before treatment?

A. Checking before you receive treatment

is 100 times better than regretting it afterward.



When choosing a clinic, look at just three things.



Whether they check skin thickness with ultrasound in advance,

whether they switch the 1.5, 3.0, and 4.5 mm tips by area,

and whether they have anesthesia options (cream, nerve block, sedation)

that match your pain tolerance.



If a clinic cannot do these three things and still fires 4.5 mm as is,

the risk of nerve irritation and temporary paralysis increases.



Q3. After Shurink,

my face seems hollowed out. Will it recover?

A. This is a case we occasionally hear in the clinic,

and last week’s case of a 49-year-old patient was typical.



She said a slight hollowed feeling beside the cheekbone

appeared two weeks after treatment.



On examination, there were signs that

3.0 mm had been used too aggressively in a person with thin subcutaneous fat.



In such cases, wait 2 to 3 months for natural recovery,

and if it doesn’t return, a light filler correction

can make it look almost unnoticeable.




If you take only one thing away from today,

— ask first not about the number of shots, but about

how the tips were divided by area.




In the next article, I’ll explain '

how far ultrasound should be used to safely apply Shurink 4.5 mm.
