“After thread lifting,

threads came out.”

“I'm worried because the swelling and bruising

were worse than I expected.”

“I only got it because they said there would be no side effects,

so why is this happening?”

If you have ever searched for thread lifting,

you may have seen reviews like these.

The real issue is not that thread lifting itself

is dangerous,

but that there is a lack of information,

and the results can vary greatly

depending on the practitioner.

Thread lifting is not simply

a procedure that inserts threads,

but a highly advanced technique that requires delicate design

and expertise in coordination with facial structure.

So today,

based on paper data,

I will clearly organize how often

thread lifting side effects occur, why they happen,

and the criteria you must check

to receive the procedure safely.

  1. What side effects can thread lifting have?

This study analyzed side effects that occurred after thread lifting procedures

in 2,827 people.

In simple terms, it is a dataset that gathered 26 thread lifting studies reported worldwide

and organized, in numbers,

how often each side effect occurred.

The results are as follows.

Bruising: 26% (one of the most common side effects)
Swelling: 16%
Pain: 11%
Skin dimpling or asymmetry: 7%
Sensory abnormality (tingling): 6%
Visible or palpable threads: 10%
Thread exposure: 5%
Infection: 2%

However, looking at the conclusion of the paper,

it states that thread lifting is generally safe,

but the frequency of side effects varies widely.

I will explain the reason for this now.

  1. Thread lifting changes depending on 'this.'

An important point mentioned in the paper is that

heterogeneity between studies was very high.

In other words, even with the same thread lifting procedure,

results differed greatly from patient to patient

and from practitioner to practitioner.

This means that the rate of side effects can change

depending on the practitioner’s skill,

thread insertion position, and design planning.

That is why thread lifting can never be expected to produce good results

simply by inserting more threads or applying more force.

Only when all of the following can be comprehensively designed:

understanding of anatomical structure, precise depth setting,

thread direction, and tension adjustment,

can the procedure help reduce side effects.

For that reason, the side effects of thread lifting can be influenced by

who performs it and how it is performed.

  1. Please be sure to follow this

In addition, thread lifting is just as important in aftercare

as it is in the procedure itself.

So the following criteria must be strictly followed.

Whether the pulling direction of the threads was designed to match the overall facial contour
Whether the pulling force was distributed so that volume does not gather in one area and look spread out
Whether depth, fixation, and tension were adjusted so the threads could stably settle within the skin

Our clinic also considers this part very important,

so rather than simply applying the technique,

we design the procedure based on what expression and impression

each patient will have after treatment.

Therefore, it is not simply a

‘procedure that pulls the face,’

but a design-centered thread lifting,

lifting that minimizes side effects,

and a safe procedure tailored to the patient’s skin condition

are our top priorities.

For this reason, even patients with sensitive skin

or reactive skin can receive treatment without worry,

and we even review cosmetic ingredient lists ourselves

before using them.

Thread lifting is not simply

‘a procedure that inserts threads.’

When design, skill,

and post-procedure care are all harmonized,

a true level of effectiveness and safety can be secured.

As the paper also showed that analyzing thousands of people revealed

a side effect rate that cannot be ignored,

if you are considering the procedure,

I strongly recommend choosing a place with a verified system

and experience.

Our clinic also takes pride in delivering highly satisfying results

to many patients through delicate design

and responsible treatment^^

I will end by saying that the procedure best suited to your face

starts with the safest design.

This has been Kim Jin-hyeon, the chief director of UNNI Clinic Mokdong branch.

Thank you.
