Top 5 Procedures and Their Effects

Hello. This is Sio Clinic.

​

The forms and depths of skin aging

vary from person to person,

so the concerns of our visitors

are also incredibly diverse.

​

Among these, there are certain procedures

that many people consistently seek out.

​

​

Today, we will organize the top five

most popular procedures at Sio Clinic,

providing an overview of their characteristics and general principles,

​

and explain how each procedure works.

1. Ultherapy: The Lifting Power from Deep Within

As we age, skin gradually sags,

and the feeling of blurred facial contours

are common changes during the aging process.

​

​

Beneath the skin's surface lies the

fascia layer, a firm fibrous structure that supports elasticity.

​

Over time, this layer loosens,

causing the overlying skin to sag as well.

Ultherapy delivers energy without

unnecessary irritation or damage to the skin surface,

​

precisely targeting this deep fascia layer

with high-intensity focused ultrasound energy.

Similar to how a magnifying glass focuses sunlight

to generate heat at a single point,

​

it creates microscopic thermal coagulation points

deep within the skin, inducing the

loose tissues to contract on their own.

​

​

The procedure is meticulous because

the energy is adjusted while directly monitoring

each individual's skin thickness and structure

on a real-time display.

​

It is recommended for those who desire

a naturally defined jawline, or for those

whose facial contours have become blurred due to

sagging in the jowl or double chin areas.

​

2. Serf: Firmness Filled with Radiofrequency

In addition to deep skin sagging,

many people are also concerned about

fine wrinkles or rough texture on the skin's surface.

​

​

When the density of the skin's surface layer decreases,

makeup can easily become patchy, and the skin

can appear lifeless.

Serf is a radiofrequency procedure that

delivers volumetric RF energy evenly from the epidermis

to the dermis, creating an internal thermal environment

and promoting collagen synthesis.

​

It stimulates the key components within the dermis,

whose amounts decrease rapidly with age,

​

helping the skin to become firmer on its own.

​

By densely filling the skin's structure,

it is recommended for those who feel their skin

is weak, loose, or flabby to the touch.

​

3. Collagen Booster: Juvelook and Healowave

This procedure focuses on enhancing the skin's

self-regenerative power, enabling it to gain strength,

rather than simply providing temporary hydration

or filling space with external substances.

​

It induces changes within the skin using

ingredients that naturally decompose over time.

Juvelook, which induces autologous collagen production,

and Healowave, which gently refines the overall

skin environment, create a positive synergy

when applied together.

​

The microparticles of Juvelook

are slowly absorbed within the dermis,

activating cellular activity around them,

and ultimately helping the skin's

natural substances to replenish.

​

​

When combined with Healowave,

skin's moisture retention increases,

and the skin barrier strengthens, alleviating

elasticity loss due to dryness.

It creates natural volume by restoring

the skin's inherent vitality, rather than

artificial fullness, so there is less concern

about an unnatural feeling.

It is highly satisfactory for those

who struggle with persistent dryness

or wish to improve their overall skin health.

​

4. Clean Cut: Smoothing Unwanted Lines

Excessive facial fat or sagging tissues

accumulated in specific areas can make

the overall impression appear heavy and dull.

​

​

Areas like under the chin and around the mouth

are particularly prone to uneven fat distribution

as we age.

Clean Cut is a meticulous procedure at Sio Clinic

that gently refines unwanted lines, such as

double chin or jowls, with precise touch.

It is a non-surgical method that avoids

the burden of bone shaving or invasive surgery,

​

reducing the volume in problematic areas

to make facial features appear more defined.

​

If excessive fat is reduced with greedy ambition,

the skin can become sunken or saggy.

​

​

Therefore, it must be designed to

smoothly connect, considering the overall

facial proportions and curves.

​

It is recommended for those who wish to selectively

refine heavy lines around the face without

compromising their natural contours and charm.

​

5. Botox: Delicate Adjustment of Expression Lines

Botox is one of the most commonly encountered

procedures, yet its results are significantly influenced

by the practitioner's delicate sense and control.

​

The various expressions we make in daily life

are created through the contraction and relaxation

of facial muscles. When this movement is repeated

over many years, deep grooves form in the skin.

Botox temporarily relaxes the specific muscles

that cause wrinkles by inhibiting neurotransmitters,

thereby preventing deep lines in the forehead,

between the eyebrows, and around the eyes from

becoming permanent.

​

Furthermore, it also plays a role in

reducing the volume of overdeveloped muscles

like the jaw muscles or chewing muscles,

softening the lower facial contour.

​

To avoid a stiff facial expression and maintain

natural harmony, it is crucial to accurately

assess the muscle size, strength, and direction

of movement, and use only the appropriate amount.

Beyond simply stopping muscle movement,

the focus is on creating a more relaxed and

gentle overall impression.

The five procedures introduced today

each act on different skin layers

and have distinct areas of effect.

​

​

The important thing is not to blindly

follow trending procedures,

​

but rather to have a personalized plan

that comprehensively considers your current

skin condition, thickness, and rate of aging.

​

At Sio Clinic, we always listen sincerely

to the stories of each and every visitor,

accurately assess their condition, and strive

to provide only the necessary treatments without

unnecessary over-treatment.

Skin's results can vary depending on

the touch of the person handling it

and the perspective with which it is viewed.
