What Is Melasma on the Face? Causes, Triggers, and Best Treatments
Melasma on the face causes dark patches, uneven skin tone, and stubborn facial discoloration over time.
Melasma on the face is a common skin condition that causes brown, gray-brown, or patchy discoloration, usually on the cheeks, forehead, nose, upper lip, and chin.
It is often triggered by sun exposure, hormones, heat, inflammation, and genetics. While melasma is harmless, it can be difficult to treat without the right skincare routine and daily sun protection.
Melasma is one of the most common forms of facial hyperpigmentation, especially in women and those with medium to deeper skin tones. It often appears as symmetrical patches and can become darker with sunlight, heat, hormonal changes, stress, and skin irritation.
At Serene Skin Health, our goal is to help you understand what melasma is, what causes it, and how to treat it with both medical-grade and lifestyle approaches.
What Does Melasma Look Like?
Melasma usually appears as flat brown or gray-brown patches on the face. The most common areas include:
- cheeks
- forehead
- bridge of the nose
- upper lip
- chin
- jawline
Unlike acne scars or isolated dark spots, melasma often appears in larger patch-like areas and usually affects both sides of the face.
Some people notice it worsening after summer, vacations, pregnancy, birth control changes, or stressful periods.
What Causes Melasma on the Face?
Melasma is caused by overactive pigment-producing cells called melanocytes.
These cells produce extra melanin when triggered by internal and external factors.
The most common causes include:
Sun exposure
UV rays are one of the biggest triggers. Even a few minutes of daily sun exposure can worsen melasma.
Hormones
Hormonal shifts are a major cause, especially:
- pregnancy
- birth control pills
- hormone replacement therapy
- estrogen and progesterone fluctuations
For a deeper look, read our guide on what hormones cause melasma.
Heat
Heat can stimulate pigment production even without direct sunlight. This includes hot yoga, saunas, cooking over the stove, and warm outdoor temperatures.
Inflammation
Harsh skincare products, aggressive exfoliation, or irritation can make melasma worse.
Genetics
Melasma often runs in families.
Why Melasma Gets Worse
Melasma is known for recurring because the pigment cells remain easily triggered.
Common worsening triggers include:
- sun exposure
- chemical sunscreens that do not provide enough mineral protection
- hormones
- heat
- alcohol
- poor sleep
- stress and elevated cortisol
- skin inflammation

Best Sunscreen for Melasma
Sunscreen is the most important step in any melasma routine.
A mineral sunscreen with zinc oxide and iron oxides is best because it protects against:
- UVA
- UVB
- visible light
- heat-related pigment triggers
Tinted mineral sunscreens are often ideal for melasma.
Be sure to reapply every 2 hours when outdoors.
Professional Treatments for Melasma
For more stubborn cases, professional treatments may help.
These may include:
- customized facials
- light chemical peels
- physician-guided medical-grade skincare
- microneedling in select patients
- pigment correction programs

Can Melasma Go Away Naturally?
Melasma may improve naturally if the trigger is removed, such as after pregnancy or stopping certain hormones.
However, many cases are chronic and require maintenance.
The good news is that with the right skincare and sun protection, it can significantly fade.
