Melasma can be one of the more frustrating skin concerns to manage, not because it is harmful, but because it can be stubborn, unpredictable and prone to returning.
It often appears as brown, grey-brown or patchy pigmentation across areas of the face, commonly the cheeks, forehead, upper lip or jawline. For some people, it appears gradually. For others, it seems to show up quite suddenly after pregnancy, sun exposure, hormonal changes or a period of heat and inflammation.
The most important thing to understand is that melasma is not just a surface pigment issue. It is usually influenced by a combination of internal and external triggers, which is why it often needs ongoing management rather than a quick one-off treatment.
What is melasma?
Melasma is a common pigmentation condition where the skin produces more pigment than usual in certain areas.
This pigment is called melanin, and it is produced by cells in the skin called melanocytes. When these pigment-producing cells become overactive, they can create darker patches or uneven areas of pigmentation.
Melasma is most commonly seen on the face, particularly in areas that receive regular sun exposure. It can affect anyone, although it is more common in women and people with skin types that tan more easily.
What causes melasma?
There is usually not one single cause of melasma. In most cases, it develops because several triggers are working together.
Common factors that may contribute to melasma include:
- Sun exposure
- Visible light exposure
- Heat
- Hormonal changes
- Pregnancy
- Certain medications
- Genetic tendency
- Skin inflammation or irritation
- A compromised skin barrier
This is why two people can have pigmentation that looks similar, but have very different reasons behind why it developed.
Sun exposure is one of the biggest triggers
Sun exposure is one of the most common triggers for melasma.
When the skin is exposed to UV light, it naturally produces more melanin as a protective response. In skin that is prone to melasma, this pigment response can become uneven and overactive, leading to darker patches across the face.
This is also why melasma often becomes more noticeable during summer, after holidays, or after periods of increased outdoor exposure.
Even small amounts of regular sun exposure can contribute to melasma returning, especially if the skin is already prone to pigment changes.
Visible light can also play a role
Many people think only UV light matters when it comes to pigmentation, but visible light can also be involved.
Visible light is the light we can see, and it is present in daylight. For some people, especially those with deeper or more pigment-prone skin types, visible light may contribute to ongoing pigmentation.
This is one reason why daily sun protection is such an important part of managing melasma. It is not just about sunscreen at the beach. It is about consistent protection as part of your everyday skin routine.
Hormones and melasma
Hormonal changes are another major factor in melasma.
Melasma is sometimes called the “mask of pregnancy” because it can appear during pregnancy, when hormone levels change significantly. It may also be influenced by hormonal contraceptives, hormone therapy or other hormonal shifts.
This does not mean hormones are always the cause, but they can make the pigment-producing cells in the skin more reactive.
For some people, melasma may fade after a hormonal trigger changes. For others, it may remain or return over time, especially when combined with sun exposure, heat or inflammation.
Why does melasma come back?
Melasma often comes back because the skin remains prone to overproducing pigment.
Even when pigmentation appears lighter after treatment, the underlying tendency can still be there. If the skin is exposed to triggers again, such as sun, heat, hormonal changes or irritation, the pigment can become more noticeable.
This is why melasma is often described as a chronic or recurring condition. It can be improved and managed, but it may need ongoing care to help reduce the chance of relapse.
Heat can make melasma worse
Heat can be a trigger for some people with melasma.
This may include hot weather, saunas, intense exercise, hot yoga, cooking over heat or working in warm environments. Heat can contribute to inflammation in the skin, and inflammation can make pigment-prone skin more reactive.
This does not mean you need to avoid every warm environment forever, but it does mean heat exposure may be something to consider if your melasma tends to flare easily.
Inflammation and irritation matter
Melasma-prone skin often does not respond well to aggressive treatment or over-exfoliation.
When the skin becomes irritated, inflamed or stripped, pigment cells can become more active. This can sometimes make pigmentation worse rather than better.
This is why a gentle, considered approach is so important. More active ingredients, stronger peels or harsher treatments are not always the answer. In some cases, calming and supporting the skin barrier is the first step.
Genetics can influence melasma
Some people are simply more prone to melasma than others.
If melasma runs in your family, or if your skin naturally tans easily, your skin may be more likely to develop pigmentation changes. Genetics do not mean you cannot improve the appearance of melasma, but they can influence how easily it is triggered and how likely it is to return.
Why melasma treatment needs to be careful
Melasma is not the type of pigmentation that should be treated aggressively without proper assessment.
Some pigmentation concerns can respond well to certain treatments, while others can become darker or more reactive if the wrong approach is used. This is especially important for melasma, because the skin may already be sensitive to heat, light and inflammation.
A careful treatment plan may include skin preparation, daily sun protection, barrier support, pigment-regulating skincare and in-clinic treatments where appropriate.
The right approach depends on your skin type, the depth of the pigmentation, your triggers, your skin history and whether your melasma is currently active or stable.
Can melasma be cured?
Melasma is usually managed rather than cured.
For some people, it may fade significantly, especially if the trigger was temporary, such as pregnancy or a medication change. For others, it may require ongoing maintenance to keep the pigment calmer and less visible.
This can feel frustrating, but it is also empowering to understand. When you know your triggers and have the right plan in place, melasma can often be managed more effectively over time.
What helps reduce the chance of melasma coming back?
There are several things that may help reduce the chance of melasma returning or becoming more noticeable.
- Consistent daily sun protection
- Avoiding unnecessary heat exposure where possible
- Using skincare that supports the skin barrier
- Avoiding over-exfoliation or harsh active ingredients
- Identifying hormonal or medication-related triggers where relevant
- Following a personalised treatment plan
- Maintaining results rather than stopping care completely once pigment fades
Maintenance is one of the most important parts of melasma care. Once the skin is calmer, ongoing support helps reduce the chance of the pigment becoming active again.
When should you seek advice?
If pigmentation is changing, spreading, becoming darker or not responding to skincare, it is best to have your skin assessed before trying stronger products or treatments.
Melasma can look similar to other types of pigmentation, so understanding what you are treating matters. A professional skin assessment can help identify whether your pigmentation is likely to be melasma, sun damage, post-inflammatory pigmentation or another concern.
From there, your clinician can recommend an approach that is suitable for your skin and your long-term goals.
