Hello.
This is Director Hwang Jeong-hwan of Cleor Clinic Gangnam Branch.
Do you often feel that your skin looks particularly dull and your overall condition is low when you look in the mirror,
leading you to take vitamin supplements?
"My skin looks dull and I catch colds frequently.
I feel like pills aren't absorbed well, so I'm wondering if there's another way."
We have been receiving many inquiries like this recently.
The human body cannot synthesize vitamin C on its own,so it is an essential nutrient that must be supplied from the outside.
Oral intake is known to have an absorption rate of about 20% in the stomach,
so even if you take the same amount, the actual amount reaching the cells is limited.
Today, I will explain what role vitamin C plays in our body,
and how intravenous (IV) nutrition differs from oral intake.
What is the Gangnam Vitamin Injection?
👉 The Gangnam Vitamin Injection is an intravenous nutrition therapy that directly administers vitamin C (L-Ascorbic Acid) into the vein,
providing antioxidant effects, supporting collagen synthesis, and assisting immune function.
The official chemical name for vitamin C is ascorbic acid.
It is a water-soluble essential nutrient that the human body cannot produce itself,
so it must be consumed through foods like fruits and vegetables or
supplemented through nutritional products.
When this ingredient is administered intravenously, it bypasses the absorption process in the stomach
and reaches the bloodstream directly, allowing for
a stable blood concentration to be achieved in a short time.
At the Gangnam branch, vitamin C IV therapy is offered either as a standalone treatment or
as an option to be considered alongside other nutritional IV therapies.
The role of vitamin C in our body
👉 Vitamin C is a water-soluble essential nutrient involved in various human systems through four main functions: antioxidant effects, collagen synthesis support, immune function support, and UV response assistance.
Antioxidant effects
Vitamin C is an ingredient with strong electron-donating properties.
It is known as an antioxidant that neutralizes oxidation reactions by
donating electrons to active oxygen (free radicals) that damage cells,
making it a popular category during periods of increased cell damage due to accumulated fatigue or stress.
Collagen synthesis support
Collagen is a key protein that supports tissues such as skin, blood vessels, and joints.
Vitamin C acts as a cofactor for the enzymes required in the process of collagen production,
so it is known as an area of high interest regarding the structural support of skin tissue.
Immune function support
Vitamin C is reported to be involved in white blood cell activation and immune cell activity.
It is a category of interest for those looking for immune management during seasonal changes or periods of low physical condition.
UV response assistance
A small amount of vitamin C naturally exists in human skin and is known to be involved in
protecting against cell damage caused by UV rays.
It is an area of high interest during periods when skin condition is affected by daily UV exposure.
Difference between oral intake and intravenous (IV) nutrition
👉 Intravenous nutrition bypasses the stomach absorption process to reach 100% of the bloodstream, allowing for a stable blood concentration in a shorter time compared to oral intake.
Difference in absorption rate — approx. 20% vs. 100%
Vitamin C taken orally is known to have an absorption rate of about 20% in the stomach.
Intravenous nutrition does not go through the digestive system and is delivered directly to the bloodstream,
so the administered amount is reported to reach the blood as is.
Blood concentration maintenance — limited vs. stable
Oral intake is characterized by being excreted through the kidneys shortly after absorption,
making it difficult to maintain high blood concentrations.
Intravenous nutrition is known to maintain a stable blood concentration,
facilitating smooth supply to cells.
Administration time — daily vs. session-based
Oral supplements require consistent daily intake,
while intravenous nutrition is a category managed on a session-by-session basis at necessary times.
This is also why those who find daily management difficult look into session-based management.
When the Gangnam Vitamin Injection is recommended
👉 The Gangnam Vitamin Injection is a nutritional IV line that gains interest during periods when skin condition is low, frequent colds and fatigue are repeated,
UV accumulation is felt significantly, or when one feels dissatisfied with the absorption of oral supplements.
Periods when skin condition is low
During times when the skin is dull and lacks vitality due to lack of sleep, stress, or seasonal changes,
it is a category of interest from the perspective of antioxidant and collagen-related nutritional support.
Periods of frequent colds and repeated fatigue
When colds occur frequently or recovery is slow during seasonal transitions or periods of low physical condition,
it is a line considered from the perspective of immune function support.
Periods when UV accumulation is felt significantly
For the purpose of skin condition management during times of frequent outdoor activities or high UV exposure,
it is a category of interest from the perspective of UV response assistance.
Periods of dissatisfaction with oral supplement absorption
For those who feel that taking vitamin supplements consistently does not provide a noticeable effect,
this line has become a category for exploring intravenous nutrition options.
Gangnam Vitamin Injection lineup
👉 At the Gangnam branch, vitamin C IV therapy is operated in 1, 5, and 10-session options and can be combined with other nutritional IV lines.
Since the number of sessions is determined based on your condition and goals,
it is generally performed once or twice a week, but can be adjusted according to individual status.
The session configuration that suits your condition and desired management direction will be discussed during the preliminary consultation.
Who is the Vitamin Injection for?
Those who feel limited in absorption even when taking oral vitamin C
Those interested in antioxidant management due to low skin condition
Those looking for immune management due to frequent colds and low physical condition
Those who need skin cell management due to frequent UV exposure
Those who want to maintain regular nutritional management on a session basis
Side effects and precautions for the Gangnam Vitamin Injection
👉 While the Gangnam Vitamin Injection is a nutritional IV line with long-term clinical safety, it is important to understand in advance that it is a category requiring prior confirmation based on individual condition and underlying diseases.
Immediately after the procedure, you may experience
mild redness, minor bruising, or brief pain at the injection site.
These are generally reported to resolve naturally within a day.
Due to the nature of IV nutrition, some may feel warmth in their fingertips or
brief dizziness during the procedure,
but the treatment is performed in a comfortable position, and if physical condition is very low,
we ensure stability by adjusting the administration speed.
Effects vary by individual, and the level of satisfaction
with session-based progress also differs from person to person.
It is a line where safety is well-managed when performed after checking your condition and underlying diseases
under the guidance of experienced medical staff.
If any of the following apply to you, the procedure may be restricted or
require prior confirmation, so please inform us during the consultation.
If you are pregnant or breastfeeding
If you have a history of kidney disease or kidney stones
If you have been diagnosed with G6PD deficiency (glucose-6-phosphate dehydrogenase deficiency)
If you are regularly taking blood-thinning medication
If you have a history of allergies to vitamin C or ascorbic acid
If you have other underlying diseases or are taking other medications
⚠️ Precautions before and after the Gangnam Vitamin Injection
👉 The Gangnam Vitamin Injection is a procedure where the perceived effect and recovery stability depend on preparation before the procedure and care afterward.

Q. How is the Gangnam Vitamin Injection different from the Garlic Injection or White Jade Injection?
They are categories with different main ingredients and areas of interest.
The Vitamin Injection (Vitamin C) is a line interested in antioxidant, collagen, and immune-related nutritional support,
the Garlic Injection (active Vitamin B1) is a line related to energy metabolism and condition recovery,
and the White Jade Injection (glutathione) is a line related to antioxidant and beauty interests,
making them options with different ingredient characteristics.
Q. Can I return to daily life immediately after the Gangnam Vitamin Injection?
It is a line that allows for normal daily activities from the day of the procedure.
However, it is better for condition management to refrain from heavy drinking or intense exercise for a few days after the procedure.
Q. I am worried about side effects; is the Gangnam Vitamin Injection safe?
It is a nutritional IV line with long-term clinical data,
and it is a category where safety is well-managed if performed after checking your condition and underlying diseases during the preliminary consultation.
We recommend undergoing the procedure in an environment guided by experienced medical staff.
Because the human body cannot produce vitamin C on its own,
it is an essential nutrient that must be supplied consistently from the outside.
Since there is a limit to the absorption rate with oral intake alone, the background for the increasing number of people looking into
intravenous nutrition for antioxidant and collagen support is clear.
The Gangnam Vitamin Injection is an intravenous nutrition therapy that directly administers
vitamin C (ascorbic acid) into the vein to support antioxidant effects, collagen synthesis, and
immune function.
At the Gangnam branch, in addition to vitamin C,
we operate various other nutritional IV lines.
From the Cinderella Injection, which is of high interest for beauty purposes,
the Garlic Injection related to condition recovery,
to the White Jade Injection explored for antioxidant and beauty purposes,
we have prepared options that you can choose
according to your interests and physical condition.
The nutritional IV direction that suits your condition
will be confirmed directly during the consultation.
If you feel that both skin condition and antioxidant management are needed,
please feel free to visit Cleor Clinic Gangnam Branch.
Even before deciding on the procedure, you can explore
the management direction that suits your condition through a preliminary consultation.
