Melasma can worsen when common triggers such as UV exposure, hormonal influences and overly aggressive laser treatments are not properly controlled.
“Doctor, why does my melasma keep coming back even after treatments?”
This is probably one of the most common frustrations I hear from melasma patients.
Many patients feel confused because they may already be using skincare consistently or even undergoing treatments, yet the pigmentation still seems to flare up repeatedly. And in many cases, it’s not because the treatment is “not working.” It’s because melasma itself is a very sensitive and reactive condition.
Over the years, I’ve noticed that melasma patients often improve initially, but then unknowingly continue exposing themselves to triggers that have repeatedly aggravated the pigmentation.
One patient I remember clearly was a woman in her early 40s who had been struggling with melasma for several years. She told me her pigmentation would improve slightly after treatments in the past, but within a few weeks, the patches kept turning dark again. At first, she thought her skin was simply “very stubborn.” But during consultation, we realised that several daily habits had been continuously triggering her melasma without her awareness.
And, this is actually very common.
The good news is that while some melasma risk factors cannot be controlled, there are still several important triggers that can be managed more proactively.
Before discussing preventable triggers, it’s important to understand that certain people are naturally and inherently more prone to developing melasma.
For example:
And these intrinsic factors are not something patients can simply “change.” Nevertheless, there are still several other important extrinsic triggers that patients can actively manage to reduce worsening and recurrence of melasma.
This is probably one of the biggest and most underestimated melasma triggers. Ultraviolet (UV) radiation stimulates pigment-producing cells in the skin, known as melanocytes, causing them to produce more melanin [4]. And unfortunately, melasma-prone skin tends to react very strongly to UV exposure.
This is why melasma often becomes darker after:
And, some patients don’t even realise how much daily UV exposure they are accumulating.
One patient told me: “Doctor, but I’m mostly indoors.”
But when we discussed her routine further, she realised she sat beside large office windows daily and frequently walked outdoors without sunscreen while running errands. These seemingly little amounts of sun exposure can add up over time.
This is why consistent sun protection is extremely important in melasma management.
I usually advise patients to use sunscreen regularly, ideally SPF 50 with PA+++ broad spectrum protection, even on cloudy days or when mostly indoors.
Other simple sun protection habits also help significantly, such as:
And, avoiding sunburn is extremely important because once the skin becomes inflamed and tanned, melasma often worsens readily.
This is another important trigger that many patients don’t realise. Now just to be clear, this does not mean patients should stop taking oral contraceptive pills, without discussing with their own doctors. But hormonal birth control pills may increase the risk of melasma in some individuals because of their hormonal effects on the skin [5].
And, I’ve seen quite a number of patients whose melasma became noticeably worse after starting hormonal medication.
One patient in her 30s told me she only started noticing persistent pigmentation after initiating oral contraceptive pills several years earlier. Again, this does not mean the medication is “wrong.” It simply means hormonal pills can influence pigment activity in certain people, as a potential side effect.
If birth control is needed, it may be worthwhile to discuss alternative contraceptive options with a gynaecologist or GP if other methods may also be suitable.
But if oral contraceptive pills are still necessary, then patients usually need to become even more disciplined when it comes to:
Because, once hormonal triggers are present, melasma often becomes more reactive overall, and a lot more challenging to treat.
This is something I’ve personally observed very frequently over the years while treating melasma patients. New patients often come to my clinic with a very similar story.
They tell me their melasma became significantly darker shortly after undergoing a series of “intensive” lasers or aggressive beauty treatments elsewhere.
And, this happens more often than people realise.
One patient came in after completing multiple high-intensity laser sessions within a few weeks.
Her cheeks were still red and irritated, and the melasma patches had become much darker than before treatment.
She told me:
“I thought stronger lasers would clear the pigmentation faster.”
And frankly, I can understand why patients think this way.
Because many people have this misconception:
“If lasers help melasma, then stronger lasers should work even better.”
But melasma does not behave that way. Melasma is actually a very “irritable” pigmentation condition. And when the skin becomes excessively inflamed, overheated or irritated, the pigment cells may react by producing even more pigmentation afterwards.
When I refer to “intensive lasers,” I usually mean treatments causing significant downtime for a few days such as:
And, melasma-prone skin often does not tolerate this type of aggressive treatment very well [6]. This is why careful and controlled treatment is usually much safer and effective, than repeatedly pushing the skin too hard.
One thing I often remind patients is this: Melasma usually responds better to “tender loving care” rather than aggressive treatment.
And, this mindset changes how patients approach their skin completely. Instead of constantly chasing stronger procedures for faster results, the focus becomes:
Once patients understand this, treatment often becomes less emotionally frustrating because they finally understand why the pigmentation behaves the way it does.
Melasma can be frustrating because it is influenced by many different triggers working together at the same time.
Some intrinsic factors, such as genetics and gender, cannot be controlled. But other important extrinsic factors, including excessive sun exposure, hormonal influences and overly aggressive laser treatments, can often be managed more proactively.
And, this makes a very big difference over time. From my clinical experience, melasma usually responds best when the skin is treated gently, consistently and thoughtfully rather than aggressively. The goal is not simply to remove pigment quickly, but it is to keep the skin stable enough that the pigmentation becomes easier to control long term.
If you are struggling with melasma or facial pigmentation, schedule a consultation with One Face Clinic for a personalised assessment and treatment plan.

Sometimes, before we even start discussing treatment, patients will ask: "Doctor, be honest with me... am I about to spend a fortune treating this?"
