Hello, I’m Dr. Jo Won-jin, and I’ve been seeing patients for 10 years.

I got filler for my nasolabial folds, but it seems like the area beside my mouth

has become even more protruded.

Filler is not simply about “filling” something;

you need to understand the overall balance of the face and its anatomical structure to perform this advanced design procedure.

Under the topic “How to Choose a Good Hapjeong Filler Clinic: 2 Tips,”

I’ll cover two criteria you must check before getting filler.

Hapjeong Filler

  1. Do they analyze the cause instead of insisting on just one procedure?

Let me explain using the nasolabial folds, which many people are curious about.

One of the most common mistakes is visiting with a predetermined answer, such as “I’m going to get 1 cc in the nasolabial folds.”

Being good at the procedure is important, but what should come first is whether the procedure is truly needed.

How to Choose a Good Hapjeong Filler Clinic: 2 Tips image 2 The cause of nasolabial folds differs from person to person, so identifying the cause comes first.

These days, some places even have systems that let you choose a procedure through a kiosk.

In such cases, the patient has already selected the procedure,

and the medical staff has almost no time to look at the face and identify the cause,

so the likelihood of choosing the wrong solution increases.

For example, the reason nasolabial folds look deep can vary greatly from person to person, as shown below.

Volume deficiency: A shadow forms because the area beside the base of the nostrils is hollow (filler is effective)

Muscle movement: The midface muscles move excessively, or decreased elasticity causes sagging (lifting or botox is needed)

Fat sagging: Fat around the cheekbone area sinks downward due to gravity and covers the wrinkle (consider a collagen booster, filler, or thread lifting for the cheekbone area)

If the wrinkle is caused by sagging fat and you try to fill it only with filler,

the face may become overly puffy and look unnatural.

Especially in areas with thin skin, such as the nasolabial folds, the material itself may show more noticeably.

That is why I always say that it is important to analyze the cause of the concern accurately.

By analyzing the patient’s skin thickness, skeletal structure, and muscle movement from multiple angles,

you need to determine whether filler is the right answer or whether it should be combined with another procedure.

Only then can you prevent the regret of receiving the wrong treatment.

Hapjeong Filler 2. Do they consider not only the immediate result but also the way it will look later?

Many people choose a foundation that “breaks down beautifully” when applying makeup, right?

The volume right after the procedure is important, but it is also necessary to predict the shape as time passes and the product is absorbed or shifts.

  1. Choose a product that disappears naturally and neatly

Filler is not a permanent procedure.

Over time, it is absorbed by the body,

and at that point it should disappear smoothly without leaving borders or uneven remnants.

To do this, the injection layer must be chosen carefully,

and the practitioner’s delicate handling is essential.

Also, you should choose products that are designed to be absorbed cleanly from the start, right?

As I mentioned in a previous post, domestically made botox products are good enough.

However, filler should be selected more carefully. I’ll explain why below.

  1. Choose verified products that minimize side effects One of the things that requires the most caution during the procedure is a “delayed immune reaction.”

This refers to a sudden swelling or inflammation that occurs months after the procedure.

To prevent this, it is necessary to follow the principles below.

  • Authentic fillers with established data: First recommend product lines whose safety has been verified through numerous clinical cases.

  • High-purity hyaluronic acid: Using a high-purity product whose impurities have been refined as much as possible during manufacturing helps minimize the chance of an immune reaction.

That is why I recommend Juvederm or Restylane, which are used the most worldwide.

(Domestic products are made by following the processes of the products above, but... they still have a higher rate of side effects.)

Because this is a substance that goes directly into my body,

checking the purity of the raw materials and the clinical data before the price

is the way to reduce any possible risk.

If you still do not know which clinic you can trust, it would be good to read the article below.

Summary of how to choose a good Hapjeong filler clinic

Filler is a highly precise procedure in which a slight difference can make a face look elegant or awkward.

If you think about the future stress caused by poor procedure results, you need to be careful when choosing a clinic.

Be sure to remember the two key points discussed today.

  • Rather than focusing only on filling, they should consider various factors such as muscle movement and sagging fat, and suggest the procedure that is truly necessary for you.

  • They should recommend high-purity authentic products and verified products that minimize delayed immune reactions.

When considering filler, it is better to always approach it conservatively, with the mindset that too much is worse than too little.

Rather than simply looking for the nearest or cheapest place, make sure to check whether they can analyze your concerns from multiple angles,

and whether they use products whose safety has been verified.

Thank you. This was Dr. Jo Won-jin.
