Not Every Brown Spot Is Melasma

Many people assume that every brown patch or dark spot on the face is melasma. As a result, they often purchase whitening creams or undergo treatments without knowing the true cause of their pigmentation.

In reality, several pigmentation disorders—including melasma, Hori nevus, and Ota nevus—can appear similar but differ significantly in their origin, depth, and recommended treatment approach.

A misdiagnosis may lead to ineffective treatment, prolonged recovery, unnecessary expenses, or even post-inflammatory hyperpigmentation.

That is why an accurate diagnosis by an experienced physician is the most important first step before beginning any pigmentation treatment.

What Is Melasma?

Melasma is an acquired pigmentation disorder that develops due to multiple contributing factors, including:

• Hormonal changes.
• Chronic sun exposure.
• Genetic predisposition.
• Skin aging.
• Pregnancy or postpartum hormonal changes.
• Hormonal medications.
• Chronic stress.

Melasma typically appears:

• On both cheeks.
• Forehead.
• Nose.
• Chin.
• In a symmetrical pattern.

Common characteristics include:

• Light to dark brown patches.
• Irregular borders.
• Darkening after prolonged UV exposure.

Because melasma is strongly influenced by hormones and UV radiation, treatment usually requires a combination of medical procedures and long-term skin maintenance.

What Is Hori Nevus?

Hori nevus (Acquired Bilateral Nevus of Ota-like Macules) is a benign dermal pigmentation disorder commonly seen in Asian adults.

Typical characteristics include:

• Multiple small gray-brown or blue-gray spots.
• Usually affects both cheeks.
• Pigment is located deeper within the dermis.
• Often develops during adulthood.

Unlike melasma, Hori nevus is not hormone-related, and topical skincare products alone generally provide limited improvement.

Because the pigment lies deeper in the skin, treatment strategies differ significantly from those used for melasma.

What Is Ota Nevus?

Ota nevus is a congenital or early-onset dermal pigmentation disorder.

Typical features include:

• Usually appears on one side of the face.
• Blue-gray or slate-colored pigmentation.
• May involve the eyelids or areas around the eye.
• Pigment extends deep into the dermis.

Since Ota nevus is fundamentally different from melasma, it often requires a specialized laser treatment protocol over multiple treatment sessions.

Why Are They Commonly Confused?

Although these conditions all appear as facial pigmentation, their underlying causes are completely different.

Melasma	Hori Nevus	Ota Nevus
Hormone-related	No	No
Usually symmetrical	Symmetrical	Usually one-sided
Brown patches	Gray-brown spots	Blue-gray patches
Changes with hormones	Rarely	Rarely
Requires different treatment	Yes	Yes

Because their appearance can overlap, visual examination alone may not always provide an accurate diagnosis.

Why Proper Diagnosis Matters Before Treatment

A common mistake is assuming that every pigmentation disorder can be treated using the same laser or skincare products.

In reality, physicians must carefully evaluate:

• Pigment type.
• Pigment depth.
• Skin type.
• Previous treatments.
• Medical history.
• Sun exposure habits.
• Hormonal influences.
• Overall skin condition.

Only after identifying the exact cause can an appropriate treatment plan be developed.
