When you wash your face in the morning and look in the mirror, have you ever felt that your skin looks duller than before, or that blemishes and melasma are getting darker and darker?
If your skin tone is uneven, it can make you look tired and older, which is why many people worry about it ㅠㅠ But the truth is, there are limits to what cosmetics alone can do.
That is why more and more people are looking for professional pigment correction clinics these days,
and in particular, the 'Quattro Pigment Correction Clinic,' which can improve multiple pigment concerns at once, is attracting a lot of attention.
Today, I’ll neatly and simply explain the Quattro Pigment Correction Clinic offered at Human Dermatology Clinic in the Seoul National University Entrance area! :)
What is the Quattro Pigment Correction Clinic?

Gwanak-gu blemish removal
Quattro pigment correction is
a customized treatment program that combines four or more laser devices to treat various pigment concerns such as melasma, blemishes, redness, and hyperpigmentation in a way that is tailored to each person’s skin condition :)
👉 Addresses multiple pigment problems at once
👉 Minimizes irritation and speeds recovery
👉 Leaves the skin tone clearer and cleaner
In particular, at Human Dermatology Clinic near Seoul National University Entrance Station, the major difference is that a board-certified dermatologist directly diagnoses and plans the treatment, rather than simply using a machine :)
Why do melasma and blemishes appear?

Seoul National University Entrance Station dermatology clinic
-
Sun exposure (UV radiation)
Ultraviolet rays (UVA, UVB) stimulate melanocytes in the dermis, increasing melanin production.
This can darken melasma and blemish areas and make them spread over a wider area.
-
Hormonal changes (Hormonal factors)
When estrogen and progesterone levels fluctuate due to pregnancy, oral contraceptives, or hormone replacement therapy, the melanin production pathway becomes activated and melasma develops more easily.
Pregnancy melasma (mammasma) is a representative example.
-
Post-inflammatory hyperpigmentation (Post-inflammatory hyperpigmentation, PIH)
As areas where inflammation has occurred, such as acne, eczema, or contact dermatitis, heal, excess melanin remains and appears as blemishes.
In particular, the stronger the skin irritation, the greater the risk of PIH.
-
Genetic predisposition (Genetic predisposition)
There are large individual differences in the sensitivity and distribution of melanocytes, and if there is a family history, the risk of developing melasma and blemishes is higher.
-
External irritants and cosmetics (Irritants & Cosmetics)
Highly irritating skincare products, strongly scented soaps, and taking certain medications can damage the skin barrier and trigger excessive melanin production.

Skin care is not something that ends after doing it once;
true change comes from approaching it consistently and correctly!
In particular, pigment disorders are influenced by many factors in combination, such as time, the environment, and lifestyle habits,
so rather than expecting only short-term results,
it is important to work out a long-term plan together with a board-certified dermatologist.

Human Dermatology Clinic near Seoul National University Entrance Station does not simply fire lasers;
it carefully assesses the patient’s skin condition, lifestyle pattern, and care habits to propose a customized solution.
It also provides professional skin care programs before and after the procedure, along with advice on lifestyle habits,
thereby increasing satisfaction with pigment treatment.
Finding not just a simple 'laser treatment,' but a 'care partner' for your skin is the best way to maintain clear skin for a long time.
We hope you, too, can create radiant skin that lasts with Human Dermatology Clinic Seoul National University Branch. ✨
