Seongsu Station, Ttukseom Station Lip Filler: The Difference is in the Details

The 1mm difference that determines facial atmosphere,

the reason lip fillers are 'dramatic'.

Hello,

This is Sio Clinic, a place that does lip fillers well at Seongsu Station and Ttukseom Station.

​

When we look in the mirror or face others, where does our gaze linger the longest? It's our eyes and lips.

This is because areas like the forehead, nose, and chin are 'static structures' that remain fixed when we make expressions, while the eyes and lips are 'dynamic structures' that move constantly when we speak or smile.

​

The starting and ending point of expressions, lips are the area that most dramatically changes the overall impression and atmosphere of the face with even the slightest change in volume and line.

Today, we will talk about the essence of lip fillers from Sio Clinic's perspective, and why we insist on 'retouching' and 'honesty'.

1. Aging makes lips retract inward.

​

As we age, lips don't just get thinner. As skin elasticity decreases, the philtrum lengthens, and the surrounding muscles that support the lips relax, causing the lips to curl inward.

​

At the same time, the distinct lip border becomes blurred.

​

Thin, retracted lips can give a cold or narrow impression. For those over middle age, lip fillers should be approached not just for aesthetics, but with the concept of 'restoration' to regain a lively and gentle impression.

​

2. Why does Sio Clinic consider 'retouching' essential?

Many people ask, "Can't you just complete it in one session?" However, Sio Clinic considers retouching an essential process due to the difference in 'swelling' and 'tissue texture'.

​

① The tissue texture inside the lips differs from left to right.

​

A person's face is not a perfect mirror image. Even with the same lips, the tissue density and the resistance when the injection needle enters are subtly different between the left and right sides.

​

The amount and number of times the filler is injected must vary based on this resistance. Mechanically injecting the same number of times on both sides is meaningless.

​

② You need to see the 'real shape' after the swelling subsides.

​

Achieving a detailed shape inevitably requires more injection sessions, which consequently causes swelling. The appearance immediately after the procedure includes swelling.

​

About a week later, when the swelling subsides and the tissue stabilizes, the exact asymmetry and insufficient volume become visible. Making fine adjustments at this point leads to a more complete and natural result.

​

Establishing the overall balance in the first session and perfecting the details in the retouching session. This is the core of the naturalness that Sio Clinic aims for.

3. More important than "I'll do it exactly as you want" is saying "This is not possible."

​

Lip fillers are ultimately a matter of 'aesthetic sense'.

However, aesthetic sense is subjective. The best results are achieved when the patient's and the doctor's aesthetic senses align.

​

Occasionally, when a patient brings a photo of the lips they desire, simply saying, "I'll make it exactly like that," can be irresponsible.

​

Structural limitations: Original lip width, degree of asymmetry, philtrum length

Overall harmony: Chin shape, marionette lines, jowl line, protruding mouth

​

Especially in cases of a structurally protruding mouth, fillers can actually make the mouth appear more protruded, so we do not recommend it.

Sio Clinic doesn't just look at the lips.

​

We consider the harmony with the chin, philtrum, and cheek lines within the overall frame of the face. Clearly explaining the possible and impossible limits, and proposing predictable results.

​

That is what Sio Clinic considers 'customized design'.

​

4. Too much is as bad as too little: The aesthetics of naturalness

While 1cc is often used as a standard, what's more important than the volume is 'the amount needed within the overall facial balance'.

​

If the lip border is blurred, we emphasize the line; if drooping corners are a concern, we address the corners with fillers; if asymmetry correction is needed, we combine lip flips and fillers.

Rather than creating an artificial shape with excessive volume, we design an atmosphere that best suits your face.

Experience lip fillers that bring vitality to your expressions with a small 1mm difference, at Sio Clinic, where they understand your aesthetic sense and offer honest advice.
