Medical Treatment for Melasma: What Works and What Can Make It Worse?

Most people who come to us about melasma have already tried something.

A brightening serum, a course of peels, perhaps a laser package that seemed to help for a month before the patches came back darker than before.

We understand the frustration. Melasma is one of the most common reasons people see a dermatologist about their skin, and it is also one of the most misunderstood.

The honest answer is that melasma can usually be improved and controlled very well, but it is a long-term condition rather than a mark you remove once. In this article, our dermatology team explains what melasma is, what triggers it, and how a careful medical treatment for melasma differs from a quick fix.

What Is Melasma?

Melasma is a common pigment condition that causes brown or greyish brown patches, usually on both sides of the face. It is also known as chloasma, and when it appears during pregnancy it is often called the mask of pregnancy.

The patches tend to sit on the cheeks, forehead, upper lip, nose and chin. They are flat, they do not itch or hurt, and they often have soft, irregular edges that look a little like a map.

Melasma is far more common in women, typically starting between the ages of 20 and 40. It is also more likely in medium to darker skin tones, including people of Asian, South Asian, Middle Eastern and Latin American background. Men can develop it too, and it is often overlooked when they do.

Dermatologists also look at how deep the pigment sits.

• Epidermal melasma sits closer to the surface and generally responds better to treatment.
• Dermal melasma sits deeper in the skin and tends to be more stubborn.
• Mixed melasma has features of both, and is a common picture in practice.

Knowing which type you have shapes the whole treatment plan, which is why we never recommend a treatment before examining the skin.

Chloasma Causes and Common Triggers

There is no single cause of melasma, or chloasma. It is better understood as skin that is primed to make extra pigment, which then gets switched on by one or more triggers.

The triggers we ask about most often are listed below.

• Sunlight: UV exposure is the biggest driver, and Australian sun is unforgiving. Visible light, including blue light, can also deepen pigment, particularly in darker skin.
• Hormones: Pregnancy, the contraceptive pill, hormonal IUDs and implants, and menopausal hormone therapy are all linked to melasma. This is why chloasma causes are so often traced back to a pregnancy.
• Genetics: Melasma commonly runs in families, so a mother or sister with it is a useful clue.
• Heat: Long periods in hot kitchens, saunas or hot workplaces may make melasma worse, even without much sun.
• Skin products and medicines: Some perfumed products and certain medications can make the skin more reactive to light.
• Irritation: Harsh scrubs, strong peels and aggressive treatments can inflame the skin, and inflamed skin tends to produce more pigment.

Smoking can also contribute to melasma and make it harder to control. Melasma has also been linked with thyroid conditions, so your dermatologist may ask about your general health as well as your skin.

Why Melasma Needs a Proper Diagnosis First

Not every brown patch on the face is melasma. Sunspots, freckles and pigment left behind after acne or a persistent rash can all look similar at first glance.

This matters because they are treated differently. A laser setting that clears a sunspot beautifully can inflame melasma and leave it darker. Some skin conditions that mimic melasma also need medical attention in their own right.

This matters because each one is treated differently. A treatment that suits one type of pigment may irritate melasma and make it more noticeable, so getting the diagnosis right comes first.

At your consultation, a Specialist Dermatologist will look closely at where the patches sit, their colour and how evenly they spread across both sides of the face. We will also ask about pregnancies, hormonal medications, your skincare routine, your work and how much time you spend in the sun. Together, these details help us understand what is driving your pigment and which treatments are likely to suit your skin.

How to Treat Melasma Medically

Medical treatment for melasma works on two fronts at once. It calms the cells that are overproducing pigment, and it protects the skin from the light that keeps switching them back on. Most people need a combination of approaches rather than one product.

1. Daily light protection, every single day

This is the foundation, and no treatment works for long without it. We recommend a broad spectrum SPF 50+ sunscreen applied to the whole face every morning, all year round, and reapplied when you are outdoors.

A tinted sunscreen containing iron oxides is often the better choice for melasma, because it also screens out some visible light. A broad brimmed hat adds a lot of protection on bright days, and so does sitting away from windows where you can.

2. Prescription lightening creams

The most effective first line treatment is usually a prescription cream that slows pigment production. Your dermatologist may prescribe a single active ingredient or a combination formula, which is generally considered the gold standard for melasma.

These creams need careful supervision. Used too strongly or for too long, some lightening agents can irritate the skin or, rarely, cause a different blue grey pigmentation. We tailor the strength, how often you apply it and how long you use it, and we often start in the cooler months when the skin is less exposed to sun.

3. Supportive skincare ingredients

Alongside prescription treatment, gentler ingredients can help keep pigment steady. Examples include vitamin C, niacinamide, kojic acid and mild exfoliating acids. On their own they rarely clear established melasma, but they are useful for maintenance and for sensitive skin.

4. Oral medication for selected patients

For some people with stubborn melasma, a dermatologist may suggest an oral prescription medicine that reduces pigment signalling in the skin. It is not suitable for everyone, especially anyone with a history of blood clots, so it is only considered after a careful medical review.

5. Looking at hormonal triggers

If melasma started or worsened after beginning hormonal contraception, it can be worth discussing alternatives with your GP. We never ask anyone to change contraception without that conversation, but it is an important piece of the puzzle.

Melasma Laser Treatment in Sydney, and Why Caution Matters

Laser and light treatments can play a role in melasma, but they are usually not the starting point. Our dermatologists may suggest them when creams alone have not been enough.

Melasma skin is reactive. Heat and inflammation can trigger more pigment, so the wrong treatment can make melasma darker or harder to treat. That is why laser should be used thoughtfully, by people experienced in treating pigment.

When we do consider light based treatment, a few principles guide us.

• Stabilise first: Pigment is calmed with medical treatment and sun protection before any device is used.
• A gentle approach: Melasma generally responds better to careful treatment than to aggressive resurfacing.
• Tailored to you: The right option, if any, depends on your skin type, the depth of your melasma and your treatment history.
• Never on its own: Any laser plan is paired with ongoing skincare and strict sun protection.

Like any procedure, laser treatment carries risks. The most common are skin irritation, redness, peeling and swelling, and your dermatologist will talk you through these before you decide.

At Glow by Quayside Medispa, our laser treatments are delivered under the supervision of our Specialist Dermatologists, in our Sydney CBD clinic. If a device is not the right choice for your melasma, we will tell you, and explain what we suggest instead.

How to Get Rid of Melasma, an Honest Answer

People often search for how to remove melasma for good. We would rather be straight with you than sell you a promise.

Melasma is a chronic condition with no known cure. With the right plan, its visibility can often be reduced, but the tendency to make extra pigment usually stays, so melasma can return with sun exposure, a pregnancy or hormonal changes.

That is not a reason to give up. It simply means the goal is long-term management. A typical journey often looks like this.

1. The first few months: Active treatment to calm and lighten the pigment. Change is gradual, so photos taken in the same light help you see progress.
2. The settling phase: Treatment is adjusted as the skin responds, and strength or frequency is often reduced.
3. Long term maintenance: A simpler routine and strict light protection keep pigment steady, with check ins before summer.

Every person responds differently, and some melasma takes longer to improve than others. Your dermatologist will talk you through what is realistic for your skin.
