Q. If I consistently apply whitening skincare products,
will my skin tone actually brighten?
A. Skincare products remain only on the outermost layer
of the skin — the surface of the epidermis.
For active ingredients to reach the basal layer,
where melanin is actually produced,
a medical approach such as laser or injection therapy
is absolutely necessary.
Q. What is the main cause of skin darkening?
A. It is a combination of excess melanin production,
dull skin tone from poor circulation,
and the accumulation of dead Keratin cells
working together.
📌 Key Takeaways from This Article
Going beyond simple whitening skincare,
a combined approach using Laser Toning and Glutathione IV
is what it truly takes
to achieve clear, radiant, luminous skin.
Why Skincare Products
Can't Reach the Basal Layer
To be straightforward — this doesn't mean whitening skincare products have no effect at all.
They certainly play a role,
but there is one important fact
we all need to understand.
The pigment-producing cells in the basal layer —
the deepest layer of our skin —
are where melanin activity is most intense.
In other words, the root cause of skin darkening
is embedded deep within the skin,
far below the surface.
Most skincare ingredients are blocked by the skin barrier,
causing them to circulate only in the upper layers of the epidermis
before absorption stops.
This is precisely why Vitamin C and other brightening ingredients
struggle to reach the melanin-producing factory
in the basal layer directly.
That temporary feeling of brightness you get
while using skincare products
is a fleeting effect caused by this very limitation in depth of penetration.
👨⚕️ Dr. Wi Young-jin's Key Insight
If you want truly clear and luminous skin,
it's time to change your approach.
You need Laser Toning
to directly break down melanin at the basal layer,
combined with Glutathione IV
to flood your body with powerful antioxidants.
Relying on just one of these two
will often leave you with results
that fall short of your expectations.
A Targeted Approach
Based on Your Skin's Root Cause
The reasons behind a dull or uneven skin tone
vary from person to person.
1. When Melanin Pigmentation Is the Primary Concern
If UV damage or melasma is your main concern,
Laser Toning is the most effective solution.
The 1064nm wavelength laser penetrates deep
into the basal layer,
selectively targeting and destroying pigment
without damaging the surrounding tissue.
2. When the Skin Looks Dull and Oxidized
If your skin lacks vitality and appears lackluster,
Glutathione IV — which delivers glutathione directly into the body — is the answer.
It neutralizes free radicals,
protects cells from oxidative damage,
and fundamentally blocks the pathway
through which melanin is produced.
3. When Rough Texture from Keratin Buildup Is the Issue
For laser and injection procedures to deliver optimal results,
the skin's foundation needs to be clean and clear.
A gentle peeling treatment to smooth and refine
your Skin Texture beforehand
significantly accelerates the brightening effect
after your procedure.
❓ Frequently Asked Questions
Q1. How often should I receive Glutathione IV?
During the initial intensive phase,
we recommend once a week for 4 to 8 sessions.
After that, depending on your skin's condition,
you can gradually extend the interval
to approximately once a month for maintenance.
Q2. Is it safe to receive Glutathione IV during pregnancy?
I do not recommend this procedure
for pregnant or breastfeeding patients.
Since the safety data has not been fully verified
for these circumstances,
I encourage you to come in for a consultation
after you have finished breastfeeding.
