Hello.
I'm Dr. Tae Hoon Kim, board-certified dermatologist at Grays Dermatology, a place that helps you find your own natural beauty.
These days, many skin care options such as laser lifting and skin boosters have emerged, yet there is one procedure many people still steadily seek out.
It's Botox.
There was a time when Botox was known as an expensive procedure and seen as the preserve of celebrities and a wealthy few.
Now, however, thanks to reasonable prices and fast results, it has become a procedure anyone can choose as part of their everyday skin care.
Especially if you'd like to slim a square jaw, are bothered by deep wrinkles on the forehead or between the brows, or want to smooth out your skin texture, you've probably considered it at least once.
Today, for those considering Botox, I'll share some helpful tips worth knowing, along with Grays Dermatology's own customized Botox solution.

How does Botox work?
Botox is a medication derived from botulinum toxin.
Because of the word ‘toxin,’ many people feel uneasy at first, but in fact, medically purified Botox is a safe drug that has been used around the world for decades.
When Botox is injected into a muscle, it temporarily blocks the connection between nerve and muscle, limiting the muscle's movement.
This prevents the muscle from contracting or developing excessively, and as a result, the muscle gradually decreases in size over time, revealing a slimmer, smoother line.
Square-jaw Botox: Botox is injected into a developed masseter muscle to make the jawline softer and slimmer.
Wrinkle Botox: reduces excessive muscle movement on the forehead, between the brows and around the eyes to soften wrinkles.
Line Botox: applied to developed muscles such as the trapezius and calves → a slimmer body line.
In other words, Botox is not simply an “injection that erases wrinkles,” but a procedure that designs the lines of the face and body by adjusting muscle strength.

When people think of Botox, the first thing that comes to mind is the square jaw.
When Botox is injected into a developed masseter, the muscle gradually decreases in size and the facial contour becomes slimmer.
Beyond the cosmetic effect, this can also help with problems such as habitual jaw clenching and teeth grinding.
Another representative area is wrinkle improvement.
Wrinkles on the forehead, between the brows and around the eyes in particular are dynamic wrinkles that deepen as muscle movement is repeated, and Botox reduces this muscle movement to help prevent the wrinkles from deepening further.
Trapezius and calf Botox are also very popular these days.
Trapezius Botox can create a longer, more graceful neckline, and with calf Botox you can expect a slimmer leg line.

Finally, an area that has been drawing attention recently is Skin Botox (also called Dermatoxin or Dermotoxin).
Small amounts of Botox are injected into the dermis, and smaller-looking pores, softer fine lines and improved skin texture can be expected.
Rather than simply paralyzing muscles, this is closer to a care concept that smooths the skin's surface.
At Grays Dermatology, rather than standard Skin Botox, we run the ‘Bicos’ program, which combines BYRYZN skin booster with Botox.
BYRYZN: high-concentration hyaluronic acid and regenerative ingredients give the skin powerful hydration and firmness.
Botox: smaller-looking pores and improved skin texture.
Combined effect: smooth skin texture + long-lasting hydration + natural firmness.
Compared with standard Skin Botox, it lasts longer and can raise the overall quality of the skin, and many patients have been satisfied with it.

When considering Botox, the first thing many people think of is price.
However, because Botox is such a widespread procedure, there are quite a few cases of people choosing based on price alone and then experiencing side effects.
- Genuine product, correct dosage: we perform treatment honestly, based on 1 vial per person, without excessive dilution.
- Accurate diagnosis: proper results come from distinguishing whether the cause is muscle, fat or bone structure. For example, if the face looks larger because of fat rather than a square jaw, lifting such as InMode is more suitable than Botox.
- Minimum dose, optimal effect: rather than injecting large amounts indiscriminately, we aim to achieve the most natural and long-lasting effect with the minimum dose needed.
In the end, what matters is who performs the procedure and how it is designed.

I believe a design is needed that considers not only your face today but also your face in the future.
We don't create artificial-looking faces through excessive treatment.
We deliver results that are natural, yet satisfying, with the minimum dose.
We perform 1:1 customized treatment, taking each patient's muscle patterns, bone structure and skin condition into account.
Before treatment, we hold a thorough consultation and explain both the effects and the possible side effects before proceeding.
We do our best so that patients not only feel the satisfaction of seeing “it's changed” in the mirror right after treatment,
but can also keep a naturally well-cared-for face months and even years later.
What makes the difference in results is not the device or the medication, but the specialist's eyes and hands, and their design philosophy.
Through 1:1 customized Botox planning for you alone, Grays Dermatology creates not just a simple change, but beauty that stays natural and harmonious over time.
