Hello.
I am Dr. Kim Dong-young, Director of Cleor Clinic Hongdae Branch.
Have you ever looked into fundamental skin care after consistently using vitamin ampoules and whitening creams that are said to be good, yet your skin tone didn't brighten and your melasma didn't fade?
"I apply vitamin serum every day, but there's no significant change.
I also use sunscreen, but my melasma and freckles still bother me.
I feel like home care has its limits, so I'm looking into clinic treatments,
but I'm curious if there's a treatment I can receive without the burden of lasers."
I often hear these inquiries in the consultation room.
While Vitamin C is a very effective ingredient for skin tone and pigmentation management,
the ingredient itself is unstable, easily destroyed by air and light,
and has characteristics that make it difficult to penetrate the skin barrier and reach the dermis.
This is why the vitamin serum you apply at home mostly stays in the epidermis,
and you don't feel a significant change.
The approach of stably delivering this Vitamin C to the dermis
is the Hongdae Ionto Vitamin Treatment.
Today, I will explain the principle of how iontophoresis penetrates vitamins,
what effects you can expect,
and how the general treatment differs from the premium treatment.
What is Hongdae Ionto Vitamin Treatment?
👉 Hongdae Ionto Vitamin Treatment is a whitening procedure that uses the principle of iontophoresis to deliver ionized Vitamin C ingredients precisely to the dermis using a weak current, thereby inducing the inhibition of melanin formation, reduction of pigmentation, and improvement of skin tone.

Iontophoresis is a method that utilizes the electrical principle that like poles repel each other.
When a (+) or (-) current is applied to ionized Vitamin C ingredients,
the ingredients move into the skin due to the force of like poles repelling each other.
Through this principle, the penetration efficiency increases by tens to 100 times
compared to applying it at home.
Unlike lasers or needle procedures, it has low skin irritation
and almost no downtime, making it a treatment you can receive without burden.
How Vitamin C acts on the skin
👉 Vitamin C that reaches the dermis acts on skin tone and condition in four ways: inhibiting melanin formation, antioxidant reaction, supporting collagen synthesis, and activating cell regeneration.
Inhibiting melanin formation

Vitamin C acts to inhibit the activity of tyrosinase, a key enzyme in the melanin production process.
As new melanin production decreases, melasma, freckles, and pigmentation
gradually fade.
Antioxidant reaction
Vitamin C is a representative antioxidant.
It neutralizes active oxygen generated by UV rays and the external environment,
slowing down skin aging and mitigating cell damage.
Supporting collagen synthesis
It acts as an essential coenzyme in the collagen production process in the dermis.
As collagen synthesis becomes smoother,
it also influences skin elasticity and the improvement of fine lines.
Activating cell regeneration
It acts to increase the regeneration speed of damaged skin cells.
This effect contributes to skin condition recovery and soothing,
and is also effective for sensitive or acne-prone skin.
Expected effects
👉 Hongdae Ionto Vitamin Treatment is a procedure that can bring various effects such as skin tone equalization, improvement of elasticity and fine lines, skin condition recovery, and mitigation of UV damage, in addition to whitening and pigmentation reduction.
Whitening and brightening
As melanin formation is inhibited,
the overall skin tone becomes brighter and transparency is restored.
As the number of treatments accumulates, the overall dark tone of the face fades,
and a clear, even skin tone is established.
Reduction of melasma, freckles, and pigmentation
Existing pigmentation gradually fades,
and new pigmentation is inhibited.
Long-standing pigmentation like melasma and freckles
progresses toward gradual reduction over several sessions.
Skin tone equalization
Uneven skin tone in different areas becomes uniform.
As the entire face is organized into a single tone,
makeup application and adhesion are improved.
Improvement of elasticity and fine lines
As collagen synthesis is supported,
skin elasticity improves and shallow fine lines fade.
It progresses toward establishing a young and healthy skin texture.
Skin condition recovery and soothing
Cell regeneration becomes active and skin condition is restored.
Soothing effects also appear on sensitive or flushed skin,
stabilizing the overall skin state.
Mitigation of UV damage
Skin damage caused by UV rays is mitigated through antioxidant action.
It acts to strengthen defense against daily UV exposure.
Difference between General Ionto Whitening Treatment and Premium Ionto Treatment
👉 At the Hongdae branch, we operate Ionto Vitamin Treatment with two options. The premium treatment combines exfoliation, ionzyme mask, LED whitening, and modeling pack, allowing for deeper absorption and a multi-layered approach.
General Ionto Whitening Treatment
This is a basic treatment that delivers Vitamin C to the dermis through iontophoresis.
It is an option you can start without burden,

and is suitable if you want regular skin tone management.
Premium Ionto Treatment - 5-Step Combination
The premium treatment combines several procedures before and after the ionto step.
① Exfoliation
First, we organize the dead skin cells on the skin surface to create an environment where vitamins can be absorbed well.
Since ingredient penetration is limited when thick dead skin cells are present,
the exfoliation step acts as a preparation process to increase absorption efficiency.
② Ionto Treatment
We deliver ionized Vitamin C to the dermis with basic iontophoresis.
Penetration efficiency increases significantly because the dead skin cells are organized.
③ Ionzyme Mask
Ionzyme is a combination method that uses sound waves (sonophoresis) and electric current (iontophoresis) simultaneously.
Much more powerful ingredient delivery occurs than when using ionto alone,
and the penetration rate of water-soluble vitamins increases significantly.
④ LED Whitening
We inhibit melanocyte activity with LED light of a specific wavelength.
At the point where the vitamins delivered by ionto/ionzyme are settling,
the LED acts together to strengthen the pigmentation reduction effect.
⑤ Modeling Pack
The final step is a mask pack that provides both soothing and moisturizing.
It mitigates initial irritation after the procedure
and finishes the treatment so that the effects settle stably.
When is which option suitable?
If you want regular skin tone management and an accessible approach, the General Ionto Whitening Treatment is suitable. If you want to manage established pigmentation like melasma and freckles in a multi-layered way, or if you also want skin condition recovery, the Premium Ionto Treatment is suitable.
Hongdae Ionto Vitamin Treatment Lineup
👉 At the Hongdae branch, we operate Ionto Vitamin Treatment in two lines: General and Premium, and they are conducted in single sessions or 5-session options.
Results settle stably when conducted consistently at 7-14 day intervals,
and the overall tone change of the face becomes distinct after completing 5 sessions.
Options suitable for your skin condition and management goals
are reviewed together during the pre-treatment consultation.
Who is Ionto Vitamin Treatment suitable for?
Those who haven't felt significant changes with home care using vitamin ampoules or whitening creams.
Those bothered by a dull and dark overall skin tone.

Those who want fundamental management for established melasma, freckles, and pigmentation.
Those who want a treatment without burden because the downtime of laser procedures is burdensome.
Those who want to maintain a clear and even skin tone through regular management.
Side effects and things to know in advance about Hongdae Ionto Vitamin Treatment
👉 Hongdae Ionto Vitamin Treatment is a non-invasive procedure, so the burden is low, but result stability depends on individual skin condition and post-treatment irritation management.
Immediately after the procedure, light redness, slight heat,
and temporary sensitivity may appear on the face.
Most of these resolve naturally within a few hours.
Ionto Vitamin Treatment is a procedure where results settle through consistent management
rather than immediate effects.
Rather than expecting a big change from a single session,
stable results are confirmed when conducted 5 or more times at 7-14 day intervals.
If UV management is insufficient after the procedure, new pigmentation may occur,
so the use of sunscreen is very important for recovery stability.
It is recommended to refrain from saunas, strenuous exercise, and drinking on the day of and the day after the procedure,
and the use of irritating home care (scrubs, strong acidic cosmetics) is recommended from one week later.
It is conducted after checking your skin condition and state
during a pre-treatment consultation guided by experienced medical staff.
If you fall under the following categories, the procedure may be restricted
or prior confirmation may be required, so please inform us during the consultation.
If you are pregnant or breastfeeding.
If you have a history of allergy to Vitamin C ingredients.
If there is an active infection or wound on the treatment area.
If you are using electronic medical devices such as a pacemaker.
If you are taking photosensitive medication.
If you have a history of recent strong peeling or laser procedures.
⚠️ Precautions before and after Ionto Vitamin Treatment
👉 Ionto Vitamin Treatment is a procedure where result stability depends on pre-treatment UV management and post-treatment irritation management.
❓ Frequently Asked Questions (FAQ)
Q. When can I see the results of Hongdae Ionto Vitamin Treatment?
Immediate whitening effects where the skin tone brightens are confirmed a few days after the procedure.
Established pigmentation like melasma and freckles show distinct changes from the point of completing 5 sessions,
and results settle more stably as you continue the management.
Q. Should I choose General Ionto Whitening Treatment or Premium Treatment?
The choice depends on the purpose of the management.
If you want regular skin tone management and an accessible approach, choose General Ionto Whitening Treatment. If you want to manage established melasma and freckles in a multi-layered way or also want skin condition recovery, Premium Ionto Treatment is suitable.

Q. How often should I get the treatment?
Results settle stably when conducted consistently at 7-14 day intervals.
Since it is a method where results accumulate through regular management, the 5-session option is frequently chosen.
Q. How much pain is involved in Ionto treatment?
Since it uses a weak current, there is not much strong pain.
You may feel a slight tingling or warmth during the procedure,
but it is not uncomfortable and you can receive it comfortably.
Q. Can I wear makeup after the procedure?
Light makeup is possible from the day after the procedure.
On the day of the procedure, avoid irritation and only use sunscreen,
and it is good for recovery stability to use mild products for a few days after the procedure.
Q. Can I receive laser and Ionto treatments together?
Parallel progression is possible.
There are combinations that are reviewed together with intervals between sessions for pigment lasers or other tone-correcting lines,
so a plan suitable for your skin condition is organized together during the pre-treatment consultation.
Q. Can men also receive Ionto Vitamin Treatment?
You can receive it regardless of gender.
It is used equally for managing dull tones or UV damage in men's skin,
so there are many cases where office workers or those with many outdoor activities receive it as regular management.
Vitamin C is an ingredient with various effects such as whitening, pigmentation reduction, antioxidant, and collagen synthesis support,
but the ingredient itself is unstable and difficult to reach the dermis, so effects are limited with home care alone.
When Vitamin C is stably delivered to the dermis through iontophoresis,
penetration efficiency increases significantly compared to home care,
and full-scale whitening and skin condition improvement proceed.
Hongdae Ionto Vitamin Treatment is a whitening procedure that delivers ionized Vitamin C to the dermis via iontophoresis to achieve inhibition of melanin formation, pigmentation reduction, skin tone equalization, elasticity improvement, and cell regeneration activation together.
At the Hongdae branch, two lines are prepared: General Ionto Whitening Treatment for those who want accessible regular management, and Premium Ionto Treatment for those who want to manage established melasma and freckles in a multi-layered way and also want skin condition recovery.
The premium treatment is conducted in a way that a multi-layered approach occurs in one session, combining exfoliation, ionto, ionzyme, LED whitening, and modeling pack.
In addition to this, various lines for pigmentation and tone management are operated at the Hongdae branch.
You can combine them according to your skin management goals, from pigment lasers that approach melasma and blemishes, skin boosters for skin texture organization, to lifting lines that are reviewed when elasticity and lifting are needed together.
The direction suitable for your skin condition and management goals will be confirmed directly during the consultation.
If you are bothered by skin tone and melasma that cannot be handled with home care,
please visit Cleor Clinic Hongdae Branch without burden.
Even before deciding on a procedure, you can check the current state of your skin together
through a pre-treatment consultation.
