Hello.
I'm Dr. Tae Hoon Kim, board-certified dermatologist and Medical Director of Grays Dermatology, located near Jung-dong Station in Haeundae.
“My jawline is fine, but my upper cheeks look hollow, and it makes me look older.”
People often think of reduced skin firmness as the only problem of aging.
In reality, however, ‘hollowing (volume loss)’ caused by the decrease of collagen in the skin makes facial aging even more noticeable.
This is why, no matter how much you lift the skin with lifting treatments, a youthful impression will inevitably remain out of reach if the hollow areas aren't restored.
Today, let's talk about filler, which naturally restores hollow areas to complete a three-dimensional, youthful face.

The real culprit that makes you look older: ‘hollowing’
Skin aging brings wrinkles on the skin's surface, pigmentation and a decline in skin texture, along with reduced firmness and hollowing caused by collagen loss and the redistribution of fat.
In addition, as the bone structure of the jaw and cheekbones regresses, the facial contour becomes less defined and the cornerstones that act as pillars of volume are lost.
Hollow areas of the face formed in this way can make the face look tired and older than its actual age.
When the cheeks flatten and the under-eye area sags and sinks, the face can change to a somewhat gloomy look, far from a lively impression.
So for a youthful face, lifting alone is not enough.
Appropriate volume restoration — that is, treatment that naturally fills in hollow areas — should be done alongside it.
Filler, as the name suggests, is an injection procedure that ‘fills’ spaces in the skin. The most commonly used ingredient is hyaluronic acid, a safe substance that naturally exists in our body.
As you know, filler works immediately, so you can see the volume fill in right after the procedure.
It helps complement hollow areas to complete a three-dimensional, younger-looking impression for a natural, youthful face.
In particular, hyaluronic acid is absorbed by the body over time, so there is less concern about long-term residue,
and it can be used not only on the forehead and cheeks but on various areas such as under the eyes, the chin, lips and nose.
Even so, many people still worry about fillers.
This is because of cases from the past.
Past filler procedures focused on long-lasting results and injected substances such as paraffin or collagen extracted from animals.
Because of foreign-body migration and immune reactions, areas of the face could look bulging, and in severe cases lumps could form.
Today, however, most fillers in use are hyaluronic acid fillers, which are naturally absorbed after a certain period and do not remain in the body.
When a skilled board-certified dermatologist performs the procedure with a minimal amount, taking balance and harmony into account, you can achieve a naturally younger look that isn't artificial at all.

I don't see filler simply as a tool for filling.
Natural results come from using it in a supporting role that completes the face's dimension and harmony.
By placing filler like pillars in supporting structures such as the deep cheeks and chin, an overall lifting effect can be achieved even with minimal volume.
And the filler procedure I aim for is one that gives the impression of being ‘well cared for,’ rather than an immediate, exaggerated change.
I use only products whose safety has been recognized through long clinical use, in ‘minimal amounts,’ aiming for the design that looks most natural with each patient's facial lines.
This requires considering the patient's bone structure, skin thickness and muscle patterns, and a 1:1 customized plan for each individual is essential.
Just as a painter with a fine brush draws delicate lines on a canvas, filler is a way of changing the impression of the entire face with a small amount.
I sincerely ask that, if you're thinking of having a large amount injected at once, you do so only after a diagnosis by a board-certified dermatologist.
That's because you most likely won't need that much.

No matter how skilled the medical team, filler can never be done naturally without a sense of design.
In particular, a lack of skill can create left-right asymmetry or, in severe cases, lumpy results.
A board-certified dermatologist should be able to use safer products and perform precise procedures based on careful design.
Whether domestic or imported, I use only products whose safety has been verified through long clinical use.
And on the principle of injecting only the minimum needed, I never perform excessive treatment.
After carefully analyzing each person's skin, bone structure and muscle patterns, I provide a 1:1 customized plan with a personal design.

Now you can see that, in creating a youthful face, filling and restoring hollowing (volume loss) is just as important as lifting, right?
Firm skin is the base, and lively, plump volume is the melody.
Filler procedures that fill in naturally, three-dimensionally and healthily are, of course, what board-certified dermatologists do well.
If hollowing makes you look older,
if you want a natural, youthful face, if you want genuine products, minimal amounts and a specialist's careful design —
Grays Dermatology will design your own beauty with safe, natural filler treatment.
