Hello, I am the director of 21 Plastic Surgery.

For localized fat, such as a double chin, abdomen, or upper arms,

we perform DCA fat-dissolving injections. For the face,

we administer stem cell skin-regeneration injections,

and we may also add stem cell intravenous injections or

an oxygen chamber to help manage overall physical condition.

However, it is best not to perform DCA fat-dissolving injections and stem cell

skin-regeneration injections on the same area at the same time.

Precisely separating the treatment areas is important.

● DCA Fat-Dissolving Injection

Reduction of localized fat, such as a double chin, abdomen, or upper arms

● Stem Cell Skin-Regeneration Injection

Improvement of facial skin elasticity and texture

● Stem Cell Intravenous Injection

Overall physical condition management

● Oxygen Chamber

Support for tissue recovery and physical condition

| What Is a DCA Fat-Dissolving Injection? |

DCA (deoxycholic acid) is a bile acid component

that breaks down fat cell membranes and is used for localized fat

in areas such as the double chin, abdomen, and upper arms.

As a result, the treated area may appear slimmer

and the body line may look more defined.

Swelling and pain may occur after the procedure,

and the results and number of treatments vary from person to person.

| What Are Stem Cells? |

Stem cells are cells with the ability

to differentiate into various types of cells and

help support regeneration when tissue is damaged.

In cosmetic procedures, it is common to use

growth factors, cytokines, and other substances

secreted during the culturing process.

In Korea, the cosmetic-purpose administration of

living stem cells themselves is strictly restricted

under the Advanced Regenerative Medicine Act. As a result,

actual products often consist of growth factor components

derived from culture medium.

| What Is a Facial Stem Cell Skin-Regeneration Injection? |

These growth factor components are injected directly into the facial skin

to stimulate collagen production

and help improve elasticity and texture.

After the procedure, the skin may be expected to feel

more elastic and moisturized.

| What Is a Stem Cell Intravenous Injection? |

The same growth factor components are delivered

through an intravenous injection throughout the body,

which may help improve fatigue and support recovery of physical condition.

Stem Cell Procedure Process

| Oxygen Chamber |

High-concentration oxygen is supplied in a sealed chamber

to help support tissue recovery and physical condition management.

Q. What are the benefits of managing

different areas separately?

The approaches to fat on the torso, facial skin, and overall physical condition

are different.

By separating the treatment areas, it is possible to manage fat reduction,

skin elasticity, and physical condition in a balanced manner

without unnecessary stimulation.

However, the expected results and whether treatment is necessary

vary from person to person, so consultation is important.

Q. Are there any precautions after the procedure?

● Temporary swelling, bruising, or pain

may occur.

● DCA fat-dissolving injections and stem cell skin-regeneration injections should not be performed simultaneously on the same area.

● If you have an underlying medical condition or take medication,

you must consult a medical professional before the procedure.

Each is a management method with a different area of action and purpose.

DCA fat-dissolving injections and skin-regeneration injections

should be performed on separate areas.

The appropriate method for you should be determined

through consultation.

Thank you.
