What is Melasma?
Melasma is a common pigmentation disorder that causes brown or gray-brown patches on the face, most often on the cheeks, forehead, nose, and upper lip. Sun, heat, and hormones can all trigger it, making melasma a frequent concern for patients in sunny Southern Arizona. At Mountain View Dermatology and Aesthetics in Tucson, AZ , our team creates customized melasma treatment plans to lighten discoloration and help prevent it from returning.
Request an AppointmentWhat Causes Melasma?
Melasma develops when pigment-producing cells in the skin, called melanocytes, become overactive and produce excess melanin. The exact cause is not fully understood, but several factors are known to trigger or worsen it:
- Sun exposure, including ultraviolet and visible light
- Hormonal changes from pregnancy, birth control pills, or hormone therapy
- Genetics and a family history of melasma
- Heat exposure, which can stimulate pigment even without direct sun
- Certain skincare products or cosmetics that irritate the skin
Melasma is much more common in women and in people with medium to darker skin tones. In sunny Tucson, AZ , year-round UV exposure and high heat make melasma especially persistent, which is why sun protection is a critical part of every treatment plan.
Signs and Symptoms of Melasma
Melasma appears as flat, brown to gray-brown patches with irregular borders. It most commonly develops on the cheeks, forehead, bridge of the nose, upper lip, and chin, usually in a symmetrical pattern on both sides of the face. It can also appear on the forearms and neck. Melasma is not painful or itchy, but it often becomes darker during summer months and lighter in winter. Because melasma can resemble sunspots, freckles, or other pigmentation concerns, a dermatologist should confirm the diagnosis before treatment begins.
Melasma Treatment at Mountain View Dermatology and Aesthetics
Melasma is a chronic condition, and the most successful approach combines prevention, topical therapy, and carefully selected in-office treatments. Dr. Marc I. Epstein and our team will evaluate your skin type, pigment depth, and triggers to build a personalized plan, which may include:
- Prescription lightening creams that slow pigment production
- Medical-grade brightening serums and antioxidants
- Gentle exfoliating treatments such as HydraFacial MD to refresh dull skin
- Carefully selected light and laser treatments for appropriate candidates, such as BBL Hero
- Daily broad-spectrum sunscreen, ideally a tinted mineral formula that also blocks visible light
Some laser and heat-based treatments can worsen melasma if they are not chosen and performed carefully. That is why it is important to work with a dermatology practice that understands pigment and adjusts treatment to your skin. Our team can also recommend medical-grade skin care products, including sunscreens from trusted brands, to maintain your results.
Melasma Versus Sun Damage
Not every brown spot is melasma. Sunspots and age spots are often treated differently, and rough, scaly sun-damaged patches may be actinic keratosis, a precancerous condition. If a spot is changing, bleeding, or growing, schedule a skin cancer evaluation. For general sun damage and uneven tone, treatments such as laser peels or Opus Plasma resurfacing may be options once melasma has been ruled out or controlled.

Melasma FAQs
Can melasma be cured permanently?
Melasma is a chronic condition with no permanent cure, but it can be significantly lightened and controlled with a consistent treatment plan and diligent sun protection.
Why does my melasma get darker in summer?
UV light, visible light, and heat all stimulate pigment production. Tucson’s intense sun and summer temperatures commonly cause melasma to darken during warmer months.
Is melasma caused by pregnancy?
Pregnancy is a common trigger, which is why melasma is sometimes called the ‘mask of pregnancy.’ It may fade after delivery, but it can persist and often benefits from treatment.
Can lasers make melasma worse?
Yes. Some aggressive laser or heat-based treatments can trigger rebound pigmentation. Our team carefully selects treatments and settings based on your skin type and pigment.
What sunscreen is best for melasma?
A broad-spectrum mineral sunscreen with SPF 30 or higher is recommended, and tinted formulas containing iron oxides add protection from visible light. Reapply every two hours outdoors.
How long does melasma treatment take to work?
Many patients notice gradual lightening within 8 to 12 weeks of consistent treatment. Ongoing maintenance helps prevent recurrence.
