Hello.
I am Dr. Kim Dong-young, Director of Cleor Clinic Hongdae Branch.
Have you ever returned home after spending a long time outdoors,
only to find your skin looking duller and more lackluster than usual in the mirror?
"With the continuous days of heavy fine dust, my skin feels like it has lost its tone,
and even with moisturizing, it doesn't feel revitalized."
When external stimuli accumulate on the skin, active oxygen builds up inside the cells.
Active oxygen is a key cause of aging that breaks down collagen and accelerates cellular aging,
so surface moisturizing alone has limitations in restoring the internal environment.
Just as opening a window in a stuffy room allows fresh air to flow in,
the Hongdae Oxygen Treatment is designed to boost your skin's condition from within by directly supplying high-concentration oxygen to tired skin.
Today, I will summarize what the oxygen treatment is,
and how the 5-step Oxygen Bubble Therapy and session options are structured.
What is Hongdae Oxygen Treatment

👉 Hongdae Oxygen Treatment is an Oxygen Bubble Therapy procedure that delivers high-concentration pure oxygen and negative ions to the skin using a dome-shaped mask,
reducing active oxygen and stimulating cellular metabolism.
The core equipment is an oxygen ion generator called O2toDerm.
It filters nitrogen from the air using an adsorption filter to create over 90% pure oxygen,
while simultaneously generating approximately 3 million negative ions.
It is known as a non-invasive care treatment with almost no downtime, as it supplies oxygen in a respiratory form without applying significant irritation to the skin surface.
As it is a supplementary care treatment that helps the skin's own recovery environment,
it is often performed in stages with other procedures or as daily condition care.
Technical Features of Hongdae Oxygen Treatment
👉 Hongdae Oxygen Treatment combines PSAT oxygen purification technology, negative ion generation, and a 5-step integrated care structure.
PSAT (Pressure Swing Adsorption) Oxygen Purification
The O2toDerm equipment uses technology to filter out nitrogen from the air through a special adsorption filter
and extract only pure oxygen.
Thanks to this method, it is known to stably supply high-concentration oxygen of over 90%.
Simultaneous Generation of Approximately 3 Million Negative Ions
The negative ions generated during the oxygen purification process
are reported to play a role in reducing active oxygen.
Active oxygen is one of the main causes of collagen breakdown, pigmentation, and skin aging,
and the mechanism involves creating an environment where negative ions reduce these effects.
Dome Mask Delivery Method
A specially designed dome-shaped mask covers the entire face,
supplying oxygen and negative ions to the skin through skin respiration.
It is a form that creates an environment without giving invasive irritation to the skin.
5-Step Integrated Care Structure
Oxygen Bubble Therapy is not a single step but consists of 5 steps,
covering everything from pore cleansing to nutrient penetration, oxygen supply, and final soothing.
Effects and Advantages of Hongdae Oxygen Treatment
👉 The core advantages of Hongdae Oxygen Treatment can be summarized into three: active oxygen reduction, non-invasive structure without downtime, and multi-step integrated soothing care.

First, it works by reducing active oxygen.
It is known to organize the skin aging environment by reducing active oxygen accumulated from fine dust, UV rays, and stress through negative ions.
Next, it is a non-invasive care with almost no downtime.
Since there are no needles, incisions, or strong heat stimulation, makeup is possible immediately after the procedure,
and there is little burden on returning to daily life.
Finally, it includes a multi-step integrated care structure.
It does not end with oxygen supply but includes pore cleansing, nutrient penetration, and soothing finishing,
making it highly versatile for condition care as it is structured within a single flow.
Types of Hongdae Oxygen Treatment
👉 At the Hongdae branch, we operate the Oxygen Bubble Therapy line with two session options: 1 session and 5 sessions,
and all options consist of the same 5 steps.
5-Step Structure
If your goal is light condition care, the 1-session option is recommended,
and if you want to gradually lift skin that has been dampened by fine dust or accumulated irritation,

the 5-session cumulative option is recommended.

The number of sessions that fits your skin condition and schedule will be determined during the pre-procedure consultation.
Who is Hongdae Oxygen Treatment for?
Those concerned about skin that has become dull due to fine dust and external stimuli
Those whose skin condition feels low even after moisturizing
Those who need soothing and recovery after breakouts or laser procedures
Those looking for options that can be received as daily care without downtime
Those who prefer gentle, non-invasive soothing and detox care
Side Effects and Precautions for Hongdae Oxygen Treatment
👉 Hongdae Oxygen Treatment is a type of care where changes become stable when performed cumulatively rather than just once.
As it is a non-invasive procedure, there is almost no pain or downtime.
However, in the case of very sensitive skin, light warmth or
mild redness may be felt immediately after the procedure, which is reported to subside within a short time in most cases.
Since oxygen treatment is a soothing, moisturizing, and condition-care procedure,
other procedures are often recommended together for strong indications like deep pigmentation breakdown or lifting.
We will look at combinations that fit your skin concerns during the pre-procedure consultation.
Please inform us in advance as the procedure may be restricted in the following cases:
If you are pregnant or breastfeeding
If there is active inflammation, herpes, or infection at the treatment site
If you have claustrophobia where breathing in an oxygen mask feels suffocating
If you have recently received strong peeling or laser procedures at the treatment site
If you have a history of allergic contact dermatitis
⚠️ Precautions Before and After Hongdae Oxygen Treatment
👉 Pre- and post-procedure care for Hongdae Oxygen Treatment affects the soothing effect and maintenance of skin condition.
❓ Frequently Asked Questions (FAQ)
Q. How is Hongdae Oxygen Treatment different from regular massage care?
While regular massage focuses on surface stimulation and blood circulation,

oxygen treatment is a device-based care that directly delivers over 90% high-concentration oxygen and about 3 million negative ions through a dome mask using O2toDerm equipment.
The biggest difference is the action area of reducing active oxygen.
Q. How often should I receive Hongdae Oxygen Treatment?
It varies depending on skin condition and exposure to external stimuli,
but in most cases, changes become stable when performed cumulatively.
The reason the 5-session option is operated is for structured, step-by-step care,
and the recommended interval will be guided during the pre-procedure consultation.
Q. Can I wear makeup immediately after receiving Hongdae Oxygen Treatment?
As it is a non-invasive care, light makeup is often possible immediately after the procedure.
There is almost no irritation to the skin surface, so there is little burden on returning to daily life.
Q. Can Hongdae Oxygen Treatment be received with other procedures?
It is often possible.
It is sometimes used as a soothing aid after procedures like lasers, peeling, or toning,
and is also used for recovery care after injection procedures.
Whether it can be performed in parallel and the schedule will be determined during the pre-procedure consultation.
Q. How long does Hongdae Oxygen Treatment take?
As it consists of 5 steps, it takes a certain amount of time when adding up the time for each step.
The exact duration varies depending on the step operation,
and it will be guided along with the schedule during the pre-procedure consultation.
Q. Is there any pain with Hongdae Oxygen Treatment?
As it is a non-invasive care, there is almost no pain.
It is performed in a form where you lie down comfortably while receiving oxygen and negative ions inside the dome mask.
Q. Does Hongdae Oxygen Treatment help with fine dust care?
When fine dust accumulates on the skin, an environment is created where active oxygen increases,
and since oxygen treatment works to reduce active oxygen through negative ion action,
it is often recommended as a soothing and detox care for those frequently exposed to fine dust.
When external stimuli such as fine dust, stress, and UV rays accumulate,
active oxygen builds up inside the skin, creating an environment where the condition gradually declines.
Hongdae Oxygen Treatment is an Oxygen Bubble Therapy that delivers over 90% high-concentration oxygen and about 3 million negative ions through a dome mask using O2toDerm equipment to reduce active oxygen and stimulate skin cell vitality.
Consisting of 5-step integrated care from whipping mask to oxygen ion dome and modeling pack finishing,
pore cleansing, nutrient penetration, oxygen supply, and soothing are all handled within a single flow.

The session configuration that suits your condition and schedule
will be confirmed directly during the consultation.
