Epidermal vs. deep dermal melasma: how they differ, which skin layer they're in, and whether they can be treated

1 What is epidermal melasma?

Epidermal melasma is a type of melasma in which pigment is concentrated mainly in the epidermis, the outermost layer of the skin. It usually appears as light brown or yellowish-brown patches spreading symmetrically across both cheekbones, the forehead and the bridge of the nose, with fairly clear borders.

The skin contains pigment cells (melanocytes) located in the basal layer of the epidermis. When stimulated by sunlight, hormones or inflammation, these cells produce more melanin than normal and push pigment up into the cell layers above. If the excess pigment sits mainly in the epidermis, the result is epidermal melasma, also called superficial melasma.

Epidermal melasma often becomes more visible after the sunny season, after a beach trip or after you stop using sun protection for a while. Because the pigment is close to the surface, epidermal melasma usually responds faster to treatment. The downside is that it also comes back easily if the skin keeps being exposed to the sun without protection.

Epidermal melasma should be distinguished from freckles (tiny, scattered dots) and age spots (spots with clear borders, usually in older people). These three conditions can appear on the same face, but their treatment protocols differ.

2 What is deep dermal melasma, and which skin layer is it in?

Deep dermal melasma is a type of melasma in which pigment drops into the dermis, below the epidermis. It is usually dark brown, gray or bluish-gray, may appear as spots or patches, has less defined borders and responds to treatment more slowly than epidermal melasma.

When hyperpigmentation persists for a long time, the basement membrane (the boundary between the epidermis and dermis) can be damaged. Melanin slips into the dermis and is "swallowed" by phagocytic cells, where it stays for a long time. This is why deep dermal melasma looks darker, with a gray-blue tint: light has to pass through several layers of skin to reach the pigment.

Deep dermal melasma is often strongly linked to hormonal factors (pregnancy, birth control pills, perimenopause), genetics and skin damaged over a long period by unregulated mixed creams or peeling creams. Some studies have also noted changes in the small blood vessels and dermis of melasma-affected skin, which contribute to its persistence.

• Epidermis: the outermost layer, where pigment cells are found. Pigment here causes epidermal melasma.
• Dermis: the layer below, containing collagen and blood vessels. Pigment that drops here causes deep dermal melasma.
• Mixed melasma: pigment is present in both layers; this type is very common in Asian women.

3 How to tell epidermal and deep dermal melasma apart

You can make a rough assessment based on color, borders and how the melasma changes with the seasons, but to know exactly whether the pigment is superficial or deep, a doctor needs to analyze your skin and assess it under a specialized lamp at the clinic.

The table above helps you picture the difference, but judging it yourself in the mirror is very easy to get wrong. Indoor lighting, makeup or areas with post-acne marks can all make melasma look different. In addition, most people who come in for an examination have mixed melasma: superficial melasma on the cheekbones with deeper gray spots in between.

At the clinic, the doctor asks about your history (when it appeared, any link to pregnancy, current medications, skincare products used), analyzes your skin and examines it under a specialized lamp to estimate the depth of the pigment. This step determines which technology to use, how much energy, and when to reassess. You can read more about realistic improvement in the article can melasma be cured.

4 Can deep dermal melasma be treated?

Deep dermal melasma can fade significantly with the right protocol and persistence, but it needs more sessions than epidermal melasma, usually combining laser, brightening mesotherapy and peels. Melasma is a chronic condition, so maintenance is needed to limit recurrence.

Topical creams act mainly on the epidermis, so for deep dermal melasma they usually help only partially. Foxy M.D doctors usually build a combined protocol, chosen according to the pigment depth and the condition of your skin. Step-by-step details are in the article medical-standard melasma treatment in Da Nang; the expected number of sessions for each type of melasma is in the article how long Pico laser takes to clear melasma.

5 Who should get a skin analysis to classify melasma, and who should postpone treatment?

Get examined when melasma spreads, keeps darkening, doesn't improve after long-term use of creams, or if you have used unregulated mixed creams. People who are pregnant, have inflamed or irritated skin, have just had strong sun exposure or are taking photosensitizing medication usually need to postpone laser and peels.

Get examined early if you:

• Have brown or gray patches on both cheeks or the forehead that appeared after giving birth, while taking birth control pills, or after age 30.
• Have used melasma creams for months but the melasma hasn't faded, or has even darkened.
• Have used unregulated mixed creams or peeling creams of unknown origin, and your skin is red, thin or stinging.
• Want to know whether you have epidermal, deep dermal or mixed melasma before choosing a treatment course.

Postpone or be cautious with laser and peels when:

• You are pregnant or breastfeeding: doctors usually prioritize sun protection and gentle care.
• The skin in the treatment area is inflamed or infected, or has eczema or severe inflamed acne.
• You have just been to the beach, are sunburned, or are taking medication that increases sensitivity to light.
• You have a history of keloid scars or pigment disorders after procedures: tell your doctor beforehand.

Note: if your skin is damaged by mixed creams, the doctor usually lets the skin barrier recover for a few weeks before starting laser, to reduce the risk of post-inflammatory hyperpigmentation.

6 Cost of treating epidermal and deep dermal melasma at Foxy M.D

According to the Foxy M.D menu effective March 10, 2026: Pico laser from $43/session, brightening peels from $33, and brightening mesotherapy from $83 depending on the product. The total cost depends on the type of melasma and the number of sessions the doctor recommends.

Epidermal melasma usually needs fewer sessions and may only require one or two methods. Deep dermal and mixed melasma usually require combining laser with mesotherapy and peels, so the cost of the full course is higher. The doctor will tell you the expected number of sessions after analyzing your skin, so you can plan your budget instead of buying a package on impulse.
