If you’ve noticed brown or grey-brown patches appearing on your face, especially across your cheeks, forehead, or upper lip, you might be dealing with melasma. Although melasma is harmless, it can be persistent and may become more noticeable with sun exposure and hormonal changes. The good news is that appropriate treatment and consistent prevention can help reduce its appearance.
In this blog, we’ll explain what melasma is, why it happens, and the most effective ways to treat and prevent it.
Melasma is a chronic skin condition that causes flat, brown or greyish patches of pigmentation to develop, usually on sun-exposed areas of the face. It occurs when melanocytes, the cells responsible for producing melanin (skin pigment), become overactive and produce excess pigment in certain areas.
Unlike a simple sunspot or freckle, melasma tends to appear in larger, symmetrical patches rather than small isolated spots. It’s far more common in women than men, and it often shows up during pregnancy, which is why it’s sometimes called the “mask of pregnancy” or chloasma.
While melasma isn’t harmful or painful, it can affect confidence and self-esteem, which is why so many people search for ways to reduce dark patches on skin and restore a clearer complexion.
Understanding the type of melasma you have helps determine which treatment will work best. Dermatologists generally classify melasma into three main types based on how deep the pigment sits in the skin:
In epidermal melasma, excess pigment is mainly located in the upper layers of the skin. It often appears light to dark brown and may respond relatively well to topical treatments.
Dermal melasma occurs when pigmentation develops deeper within the skin. It can appear bluish-grey or light brown and may be more difficult to treat since topical creams often can’t penetrate deep enough.
Mixed melasma contains characteristics of both epidermal and dermal pigmentation. Treatment may involve topical medications, sun protection, and, in selected cases, procedures recommended by a dermatologist.
There is no single cause of melasma. It usually develops because several factors activate pigment-producing cells.
Sun exposure is one of the most important triggers of melasma. Ultraviolet radiation stimulates melanin production, which can make existing pigmentation darker and contribute to recurrence. Visible light can also worsen melasma, particularly in people with darker skin tones.
Hormonal changes can stimulate melanin production. Pregnancy is a common trigger, while hormonal contraceptives and hormone-related changes may also contribute in some people.
People with a family history of melasma may have a higher risk of developing it. Skin type and genetic susceptibility can also influence how easily pigmentation develops.
Some medications can increase sensitivity to sunlight or otherwise contribute to pigmentation. If you notice melasma after starting a medication, discuss it with your doctor rather than stopping the medicine yourself.
In addition to UV radiation, visible light may contribute to melasma, particularly in people with darker skin tones. Heat may also aggravate melasma in some individuals. This is why protecting your skin from sunlight and excessive heat can be an important part of managing pigmentation.
Harsh skincare products, excessive exfoliation, or products that cause burning and irritation can potentially worsen pigmentation. Gentle skincare is therefore important when managing melasma.
There isn’t a single treatment that permanently removes melasma for everyone. Treatment depends on the type and severity of pigmentation, your skin type, previous treatments, and possible triggers.
A dermatologist may recommend one or a combination of the following:
Topical treatments are often an important part of melasma management. Depending on your condition, a dermatologist may recommend ingredients such as hydroquinone, tretinoin, azelaic acid, or other pigment-reducing agents. Some skincare products may also contain ingredients such as vitamin C or kojic acid.
Chemical peels use controlled exfoliation to help reduce superficial pigmentation and improve skin tone. Depending on your skin type and pigmentation, a dermatologist may consider peels containing ingredients such as glycolic acid or salicylic acid. Because irritation can worsen melasma or trigger post-inflammatory hyperpigmentation, the type and strength of the peel should be carefully selected by a professional.
Laser and light-based procedures may be considered when topical treatments do not provide sufficient improvement.
Advanced treatments like Q-switched lasers, fractional lasers, and Intense Pulsed Light (IPL) target excess pigment at deeper layers of skin.
These treatments need to be selected carefully because melasma can recur, and some procedures can trigger additional pigmentation, particularly in darker skin tones.
Microneedling involves using fine needles to create tiny, controlled punctures in the skin. It may be considered as an additional treatment for melasma in selected patients, sometimes alongside topical treatments. Because procedures can cause irritation or post-inflammatory pigmentation, microneedling should be performed by a qualified professional after assessing the skin.
Tranexamic acid may be used as a treatment option for melasma in selected patients. It may be prescribed in oral or topical forms depending on the individual’s condition.
Oral tranexamic acid is not suitable for everyone and can carry risks, including an increased risk of blood clots in susceptible individuals. A dermatologist should review your medical history, medications, and risk factors before considering this treatment. Never take tranexamic acid for melasma without medical supervision.
Since melasma is highly sensitive to triggers, prevention plays as big a role as treatment. Here are some essential prevention steps:
Use a broad-spectrum SPF 30+ sunscreen every single day, rain or shine, and reapply every 2-3 hours if you’re outdoors. Look for sunscreens with iron oxide, which also protect against visible light.
Hats, sunglasses, and umbrellas add an extra layer of defense against UV exposure.
Try to limit long periods in direct heat, such as cooking over open flames or prolonged sauna sessions.
If you’re on birth control or hormone therapy and notice pigmentation, consult your doctor about alternatives.
Avoid harsh scrubs or irritating products that can trigger inflammation and worsen pigmentation.
Even after your melasma has faded, continuing with a maintenance skincare routine helps prevent recurrence.
Melasma can feel frustrating to deal with, but it’s a manageable condition with the right combination of treatment and prevention. Whether you’re just starting to notice patches or have been dealing with melasma for years, professional guidance can make all the difference in achieving clearer, more even-toned skin.
Melasma is a specific type of hyperpigmentation that usually causes symmetrical brown or grey-brown patches on the face. Hyperpigmentation is a broader term that includes sunspots, post-inflammatory pigmentation, and other causes of darkened skin.
Melasma treatment usually takes several weeks to months to show noticeable improvement, depending on its severity and the treatment used.
Melasma can often be significantly reduced, but it may recur because of sun exposure, hormonal changes, and other triggers. Long-term sun protection and maintenance treatment can help control pigmentation.
Laser treatment can help reduce melasma in selected patients, but it cannot guarantee complete or permanent removal. A dermatologist should assess your skin first because some laser treatments may worsen pigmentation.
Yes, melasma is common during pregnancy because hormonal changes can stimulate increased melanin production.
Genetics can increase the chances of developing melasma, particularly if close family members have experienced it. However, hereditary factors are only one part of the picture, with sunlight and hormones also playing important roles.
A broad-spectrum SPF 30 or higher sunscreen is recommended, and a tinted sunscreen containing iron oxides may provide additional protection against visible light. Apply it daily and reapply when spending extended time outdoors.
