Melasma Series Part 4 - Lifestyle Habits That Worsen Melasma
Discover the daily habits that worsen melasma, from UV exposure and heat to skin friction and stress, and learn how to manage them effectively.

Daily Management is as Important as Treatment
While treating melasma, I often receive questions like these:
‘I am getting laser treatments, so why is my melasma coming back?’
‘I am taking good care of my skin, so why does it keep appearing?’
Melasma is not simply a condition of excess pigment. It is a condition where various factors interact, such as:
UV rays
Heat
Inflammation
Oxidative stress
Skin barrier damage
All these elements work together to affect the skin.
Therefore, while treatment is important,
how you manage your skin in your daily life can significantly impact the progress of your melasma.
Today, let us summarize the typical lifestyle habits that can worsen melasma.
1️⃣ Sun Exposure
The most significant aggravating factor for melasma is ultraviolet (UV) radiation.
UV rays can induce the following in the skin:
Increased melanin production
Inflammatory responses
Oxidative stress
Basement membrane damage
In particular, melasma can be affected by:
UVB
UVA
And even some visible light.
✔ Using sunscreen
✔ Reapplying when going outdoors
✔ Wearing a hat during prolonged outdoor activities are all crucial.
In melasma treatment, sun protection is the absolute foundation.
2️⃣ Heat Stimulation
Melasma is a pigmentary disorder that is also affected by heat.
When the skin temperature rises, it can increase:
Vasodilation
Inflammatory responses
Stimulation of melanin production
Therefore, if the following situations are repeated, melasma may worsen.
For example:
Saunas
Hot compresses
Long, hot showers
Dietary habits involving a lot of hot foods
Of course, you do not need to avoid these activities completely,
but it is advisable to reduce excessive heat stimulation.
3️⃣ Skin Friction
The habit of frequently rubbing the skin can also worsen melasma.
Typical examples include:
Strong friction during cleansing
Rubbing the face vigorously with a towel
Frequent exfoliation
Using facial massage devices
Friction can create microscopic inflammation in the skin,
and this inflammation can, in turn, stimulate melanin production.
Therefore, for melasma patients,
✔ Gentle cleansing
✔ Minimizing friction is crucial.
4️⃣ Irritating Cosmetics
The skin barrier of melasma patients is often weaker than expected.
Thus, the following products can cause skin irritation.
For example:
Strong exfoliating products
Cosmetics with heavy fragrances
High-concentration functional cosmetics
Irritating whitening products
Such irritation can lead to:
Contact dermatitis
Skin inflammation
And as a result, hyperpigmentation can become more severe.
Therefore, using cosmetics focused on protecting the skin barrier is important in melasma management.
5️⃣ Lack of Sleep and Stress
Recent studies have reported that oxidative stress may be related to melasma.
Lack of sleep or stress can be linked to:
Increased oxidative stress
Increased inflammatory responses
Additionally, melatonin, a hormone related to sleep,
is known as a substance with antioxidant effects.
If you lack sleep, these protective mechanisms can weaken.
Therefore,
✔ Getting enough sleep
✔ Managing stress can also help in managing melasma.
6️⃣ Highly Irritating Skin Procedures
For skin with melasma,
Strong peels
Excessive laser treatments
Repeated skin irritation
can worsen pigmentation.
In particular,
Dermatitis
Contact dermatitis
If irritant reactions occur,
post-inflammatory hyperpigmentation may develop.
Therefore, an approach that manages the skin stably is crucial in melasma treatment.
Summary
Melasma treatment is not determined solely by the procedures you receive at the clinic.
In your daily life, factors such as
UV exposure
Heat stimulation
Skin friction
Cosmetic irritation
Lack of sleep
Stress
can influence the progression of melasma.
Therefore, in melasma management,
✔ Sun protection
✔ Minimizing skin irritation
✔ Lifestyle habit management must go hand-in-hand to expect more stable results.
