I'm going to start with something most doctors won't say out loud.

Sometimes I can't tell you with certainty what your pigmentation is.

Not because I haven't looked properly, and not because I don't have the instruments. Because most of the time, what's actually on your face isn't one clean condition. It's a mixture — melasma with post-inflammatory marks on top of it, or melasma sitting alongside sun damage that's been accumulating for twenty years, or something that started as one thing and got layered over by another. Real faces are messy. The textbook photos are not.

So here's how I actually work, and I'd rather you know it upfront.

I ask a lot of questions first. When did it start? Was there something before it — a rash, a burn, a course of some cream, a period where your skin was irritated? Any pregnancies, and did it change afterwards? Any hormonal medication? That history matters more than people expect, and honestly, most of it is me preparing myself rather than you. By the time I look at your face and put the dermatoscope on it, I've usually already narrowed things down in my head.

Then I tell you what I've found. Where it's clear, I'll name it. Where it isn't clear, I'll say so plainly — this part I'm confident about, this part I'm not, and here's why.

That last bit sometimes surprises patients. But I've never understood the alternative. If I invent a confident-sounding label to fill the silence, and then the treatment doesn't do what that label predicted, you'd have every right to be annoyed with me. Whereas if I tell you upfront that we're dealing with a mixed picture, and we agree on what we're aiming for, then we're working together on something honest.

And I do still treat it. Almost everyone who walks into my room with pigmentation doesn't come in wanting a perfect diagnosis. They come in wanting improvement. That's a completely reasonable thing to want, and we can usually work towards it — as long as we've talked properly about what's realistic first.

What melasma actually is

Melasma is a pigmentation condition, usually symmetrical, usually across the cheeks, forehead, upper lip or jawline. The pigment-producing cells in your skin become overactive and start depositing more pigment than they should.

Three things drive it. Hormones — which is why it's far more common in women, why pregnancy is such a frequent starting point, and why hormonal medication can set it off. UV light, obviously. And visible light — ordinary light you can see, which is the part almost nobody in Malaysia knows about and which I think explains a great deal about why melasma here is so stubborn.

The single most important thing to understand is this: melasma takes years to form.

Not weeks. Years. It builds slowly, in the background, through thousands of hours of accumulated light exposure and hormonal signalling, until one day you notice in a particular light that the sides of your face don't match the middle.

Everything else in this post follows from that sentence. If something took years to develop, it is not going to disappear in a fortnight, and any product or person promising otherwise is either misinformed or selling you something.

What treatment can realistically do

Let me set the expectation properly, because this is the conversation I have most often.

We are aiming to reduce and then control melasma. Not to erase it and be done.

Realistically: some patients see a little change at around one month. That's early, and I'd rather you didn't judge anything by it. The more meaningful assessment point is at three months and beyond. Then, typically, we reach a certain level of improvement — a plateau where things have settled about as far as this approach is going to take them — and at that point we shift into maintenance.

And I want to be direct about maintenance, because this is where melasma differs from most other skin conditions I treat.

Melasma maintenance requires more discipline than eczema does. I don't say that lightly. With eczema, if you're slack for a week, you might get away with it. With melasma, if you skip sunscreen a few times and you're out in direct sun, I can often see the darkening at your next visit. It's that responsive. The pigment cells don't need much encouragement to go back to what they were doing.

So the honest framing is: this is a long-term relationship with your skin, not a course of treatment you complete. If that sounds discouraging, I'd flip it around — patients who understand this from day one do much better than patients who spend a year looking for the version where they don't have to.

Sunscreen is not the supporting act

If you take one practical thing from this page, take this.

Most people think sunscreen is for UV. It's for two types of UV, and also for visible light — and the visible light part is, in my view, the hidden reason melasma recurrence rates in Malaysia are so high. Ordinary daylight, coming through a window, reflecting off a wall, sitting on your face while you drive, will drive melasma. You don't need to be at the beach.

So what I look for in a melasma sunscreen is three things together: SPF 50+, PA++++, and iron oxide, which is what gives protection against visible light and is why these products are tinted rather than clear. The one I use in the clinic is Derm Eden DD Cream, for exactly those reasons.

Now, application. I've learned something over the years about giving instructions, which is that the more choices I give someone, the worse the decision they make.

If I say "reapply every four to six hours, or more often if you're outdoors, depending on your activity" — what actually happens is that the patient goes home and interprets it, and negotiates with themselves, and the practical outcome is once a day or not at all. I've watched this play out too many times.

So my rule is deliberately blunt:

At least twice a day, every day — even if you're indoors the entire day.
Every two to three hours if you're going to be in direct sunlight.

That's it. No conditions, no judgement calls. I'd rather give you a simple rule you'll actually follow than a precise one you'll quietly abandon.

Two other things people get wrong: not using enough (there's a two-finger guide for the face and most people use a fraction of it), and cutting back once the skin improves because it feels wasteful. The improvement is the sunscreen working. Cutting it back is how you lose the ground you gained.

The two treatment routes

Once we've talked about sunscreen, the medication conversation is essentially a fork in the road, and I let patients choose with full information.

The route with hydroquinone. This is the faster one. Hydroquinone is an effective pigment-reducing agent, used in a combination prescription cream, applied thinly at night only, for a defined period of around two months — then off it, and onto a maintenance phase. The reason for that structure is that hydroquinone is not something you use indefinitely. Used continuously for very long periods, it can cause a paradoxical darkening called exogenous ochronosis, which is difficult to treat and which I'd rather never see in one of my patients. So I explain what it is, what it does, what the risks are and how the on-off structure protects against them — and then the decision is yours.

The route without hydroquinone. Slower, gentler, and completely legitimate. This uses agents like azelaic acid, tretinoin, and tranexamic acid — topically and, in appropriate patients after proper screening, orally. Oral tranexamic acid is a genuinely useful tool in melasma, but it is a prescription medicine with real contraindications, so it requires screening before starting, monitoring on treatment, and a doctor who knows your history. It is not something to source yourself online, and I'd ask you not to.

For some patients I'll prescribe compounded preparations rather than off-the-shelf products, because the combination or concentration I want for their particular skin doesn't exist commercially.

Which route is right depends mostly on one question: how much do you care about speed versus gentleness? There isn't a wrong answer. I've had patients take each route and do well.

Why I don't offer lasers or peels for melasma

I'm often asked, so let me be clear about my position.

I don't do procedures for melasma. Not because procedures don't affect pigment — they do, and for several otherpigmentation problems they're useful.

But melasma isn't a pigment deposit sitting there waiting to be removed. It's an active, ongoing process in overactive cells that are responding to light and hormones every single day. You can remove pigment, and the cells will simply make more — and with melasma there's a real risk of the treatment itself provoking things and leaving you worse than before.

So my approach is sun protection plus topical treatment: reduce it, then maintain it. Rather than remove it and watch it come back. I know that's less exciting than a machine. I'd rather be honest about what actually holds up over years.

If your pigmentation turns out to be something other than melasma, that's a different conversation, and part of why the diagnosis discussion at the start matters.

About whitening products

Briefly, because it deserves its own post.

Think about the difference between a medication and a cosmetic whitening product. Medications contain ingredients proven to work, which is precisely why they're kept under medical supervision — because something effective enough to change your skin is also capable of harming it if used wrongly.

Cosmetic products are usually built around "natural" ingredients, which mostly work modestly at best. And here's the logic I'd like you to sit with for a moment: if those natural ingredients were genuinely powerful, we would have found out long ago, and we'd be using them in medicine too. We're not hiding them from you.

So when a whitening product produces dramatic results in three weeks, ask what's actually in it. Because too often the answer is undeclared medication, or worse, mercury and other prohibited ingredients — things that will lighten skin and cause real harm doing it.

Too good to be true usually is.

Coming to see me

My consultations for skin are roughly ninety percent conversation and ten percent prescribing, and melasma is one of the conditions where that ratio matters most. The history is doing a lot of the diagnostic work, and the expectation-setting is doing a lot of the treatment work.

Once we start, I'll review you at around one month and again at two months — to look at progress, and to check for side effects. And you're welcome to message before that if anything concerns you. You don't need to wait for the appointment.

简要说明

我是陈医生，亚庇 Lintas Square 的 Klinik Dr Tan（皮肤与暗疮）。我是对皮肤有专长的普通科医生，不是皮肤专科医生。

关于黄褐斑（melasma）：

诊断有时候真的不容易，因为脸上的色素多数是「混合型」——黄褐斑加上炎症后色素沉着，或再加上多年的日晒损伤。我会先详细询问病史（何时开始、之前有没有皮肤发炎、怀孕、荷尔蒙药物），再检查和用皮肤镜。清楚的我会告诉你，不清楚的我也会老实说不清楚。
黄褐斑是几年慢慢形成的，所以不可能几个星期就消失。目标是减淡然后长期控制，不是根除。
时间表：一个月可能看到一点变化，但真正应该评估的是三个月以后。到某个程度后就转入维持阶段。
黄褐斑的维持比湿疹更需要纪律。防晒断几次、又晒到太阳，下次复诊我通常就看得出变深。
防晒是治疗的核心，不是配角。 多数人以为防晒只防紫外线，其实还要防可见光——这是马来西亚复发率高的隐藏原因。我看三样：SPF 50+、PA++++、含氧化铁（iron oxide）。诊所用的是 Derm Eden DD Cream。
我的防晒规则很简单：每天至少两次，即使整天在室内；直接晒太阳的话每两三小时补一次。规则越复杂，执行率越低。
两条治疗路线：一是含对苯二酚（hydroquinone）的处方药膏，见效较快，晚上薄擦，用约两个月后停，再进入维持期——因为长期不间断使用可能引起外源性褐黄病（exogenous ochronosis）。二是不含对苯二酚的路线：杜鹃花酸、A酸、传明酸（口服与外用）。口服传明酸是处方药，必须先筛查、治疗中监测，不要自己上网买。
我不为黄褐斑做激光或换肤。 黄褐斑是持续活跃的过程，不是等着被清除的色素。清掉了细胞还会再制造，甚至可能被刺激得更严重。我的做法是防晒加外用药：先减淡，再维持。
美白产品：真正有效的成分之所以被列为药物，正因为它有效也可能伤人。若「天然成分」真的那么强，医学界早就在用了。效果太快太夸张的产品，往往含有未标示的药物、汞或禁用成分。
