[Seongsu/Ttukseom] Top 5 Most Popular

Procedures at Sio Clinic and Their Effects

Hello, this is Sio Clinic.

Because the form and depth of skin aging

vary for everyone,

the concerns of those who visit us

are inevitably diverse.

Among them, there are certain procedures

that many people consistently seek.

Today, we will summarize the features and

general principles of the five most popular

procedures at Sio Clinic so you can

understand them at a glance,

and explain how each procedure

works.

1. Ultherapy, the power to lift from deep within

As we age, the feeling of skin sagging

and facial lines blurring

is a common change experienced during the aging process.

Beneath the skin surface, there is a

fascial layer, a firm fibrous membrane structure that supports elasticity,

and as time passes, this layer loosens,

causing the outer skin to sag downward as well.

Ultherapy is a device that delivers

high-intensity focused ultrasound

energy precisely to this deep fascial layer

without causing unnecessary irritation or damage

to the skin surface.

Similar to the principle of using a magnifying glass

to focus sunlight and generate heat at a single point,

it forms micro-thermal coagulation points deep inside the skin

to induce the loosened tissue

to contract on its own.

Because we adjust the energy while directly viewing

each individual's skin thickness and structure

on a real-time monitoring screen,

the procedure process is precise.

We recommend it for those who want a naturally refined jawline,

or those whose overall facial contours have become blurred

due to sagging jowls or a double chin.

2. Serf, firmness filled with radiofrequency

Just as much as deep sagging,

many people are also concerned about

fine wrinkles or rough texture on the skin surface.

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

makeup easily cakes and the skin looks lifeless.

Serf is a radiofrequency procedure that delivers

three-dimensional RF energy evenly

from the epidermis to the dermis,

creating an internal thermal environment

and promoting collagen synthesis.

It stimulates the core components within the dermis

whose amounts decrease rapidly with age,

playing a role in helping the skin

become firm on its own.

Because it fills the skin's density with firmness,

we recommend it for those who have felt

that their skin is limp or flaccid

when touched.

3. Collagen Booster, Juvelook and Hilo Wave

Beyond simply providing temporary moisture

or filling space with external substances,

this procedure focuses on the skin's self-regeneration,

giving the skin strength on its own.

It utilizes components that naturally decompose over time

to induce changes within the skin.

Juvelook, which induces self-collagen production,

and Hilo Wave, which gently refines the overall skin environment,

create positive synergy when applied together.

The micro-particles of Juvelook

are slowly absorbed within the dermis,

activating cellular activity around them,

and as a result, helping the skin's natural substances

to plump up.

When combined with Hilo Wave,

the skin's moisture retention increases

and the barrier becomes stronger,

alleviating elasticity loss caused by dryness.

Because it creates natural volume

by restoring the vitality you originally possessed,

rather than artificial volume,

the burden of foreign body sensation

is low.

Satisfaction is high when internal dryness is not easily resolved

or when you want to healthily boost

the overall health of your skin.

4. Clean Cut, smoothing out unnecessary lines

Excessively developed fat on the face or

sagging tissues clumped in specific areas

make the overall impression look heavy and dull.

Especially under the chin or around the mouth,

fat distribution easily becomes unbalanced with age.

Clean Cut is Sio Clinic's own meticulous procedure

that gently refines unnecessary lines

such as a double chin or jowls

with precise touch.

It is a non-surgical method that does not go through

burdensome surgical processes like cutting bone or incisions,

reducing the volume of problematic areas

to make facial features appear more defined.

If you reduce fat excessively out of greed,

the skin may actually become indented or sag,

so it must be designed to connect smoothly

by considering the overall ratio and curves of the face.

We recommend it to those who want to selectively refine

only the heavy lines around the face

without compromising their natural contours and charm.

5. Botox, delicate adjustment of expression wrinkles

Botox is the most common procedure,

yet it is one where the practitioner's delicate sense

and control ability greatly influence the results.

The various expressions we make in daily life

are created through the contraction and relaxation of facial muscles,

and if this movement is repeated for years,

deep furrows form on the skin.

Botox temporarily relaxes the neurotransmitters

of specific muscles that cause wrinkles,

preventing wrinkles from setting in on the forehead,

glabella, and around the eyes

that deepen when making expressions.

Furthermore, it also performs the role of

reducing the volume of excessively developed

square jaws or masseter muscles,

refining the lower facial line more smoothly.

Only the appropriate amount must be handled

by accurately identifying muscle size, force intensity, and movement direction

so that expressions do not become stiff

and natural harmony can be maintained.

Beyond the concept of simply stopping muscles,

it focuses on making the overall impression

more comfortable and softer.

The five procedures introduced today

each act on different skin layers

and their areas of effect are also distinct.

The important thing is not to blindly

follow trendy procedures,

but that a one-on-one plan that comprehensively considers

your current skin condition, thickness, and aging progression speed

must come first.

Our Sio Clinic always sincerely listens

to the stories of each and every person who visits,

and we aim to present only the necessary directions

without unnecessary over-treatment by precisely identifying conditions.

The results for skin can vary

depending on the touch of the person handling it

and the perspective they view it with.
