5 Acne Mistakes You're Probably Making

Usual caveat: not a lecture. Almost everyone who arrives with stubborn acne has been trying hard — often for years, often expensively. These are traps, not accusations.

1. Trusting unverified sources

Skincare advice on social media is a genuinely enormous industry, and almost none of it is answerable to anyone.

The person recommending something to you has usually not examined a single patient, has no way of knowing what your skin is actually doing, and — this is the bit that gets missed — is frequently showing you results from something other than what they're recommending. Someone with clear skin on a prescription regime, selling you a serum.

That's before the more basic problem: you're watching a filtered sample. The people it worked for, posting during the window it was working, with lighting they chose.

I'm not going to tell you not to be on social media. But I'd apply one test to anything you see there:

would this person still be recommending it if it didn't sell?

2. Not understanding products versus medications

This is the most useful distinction on this page, and it applies well beyond acne.

Medications contain ingredients that are proven to work. That's why they're regulated, and often why they need a prescription — because something powerful enough to genuinely change how your skin behaves is also capable of causing problems if used wrongly. The regulation exists because the ingredient works, not despite it.

Products are mostly not proven. And here's the part I'd like you to sit with: even the ones that are have marginal benefit compared to medications.

Not zero. Marginal.

That's not snobbery about skincare. It's a statement about the size of the effect. A well-formulated product might make a small difference. A properly-titrated combination of benzoyl peroxide, azelaic acid and a retinoid changes what your skin does.

So when someone has spent three years and considerable money cycling through products and their acne is unchanged — that's not because they picked the wrong products. It's because they were operating in the wrong category the entire time.

If the whole category produces marginal benefit, then no amount of searching within it finds you a large one.

3. Believing you need a ten-step routine

Ten-step routines are popular, extensively marketed, and mostly unnecessary.

The reasoning offered is usually about barrier repair — that your skin barrier is damaged and needs an elaborate sequence of products to restore it.

Your barrier does matter. But a barrier is repaired by not damaging it, far more than by applying seven things to it. Fewer harsh cleansers, less scrubbing, less over-washing, and not layering multiple actives on top of each other without supervision.

And there's a specific problem with elaborate routines in acne: more steps means more opportunities for irritation, and more chances that something in the stack is working against your actives. I regularly meet patients whose ten-step routine contains three things that shouldn't be there, and the acne treatment underneath never had a chance.

What actually works is simple: a gentle cleanser, your actives, sunscreen, and a moisturiser if you need one. That's it. Anything more needs a reason, not just a marketing narrative about barrier repair.

Something else worth naming: complexity is popular partly because it's complex. A ten-step routine feels like effort, and effort feels like it should produce results. It doesn't necessarily.

4. The hydration myth

This one deserves its own space, because it's the most successful piece of skincare marketing of the last decade.

Hydration has been sold as the answer to everything — acne, pigmentation, wrinkles, every problem, same solution.

Hydration matters. I'm not dismissing it. But it's been elevated far beyond what it does, and here's the mechanism behind why.

Hydration produces fast, visible results. Use a sheet mask and you'll see a difference immediately — plumper, smoother, better.

And a few hours later, it's gone.

That's the whole phenomenon. A temporary cosmetic effect from water content, not a change in how your skin functions.

Now think about why the industry likes this so much. It's fast, so it feels effective. It's temporary, so it's repeatable — which means repeat purchases. And it carries almost no risk to the manufacturer, unlike actives, which genuinely work but can cause irritation and therefore complaints.

So there's a commercial logic pushing you towards something that gives immediate feedback and no lasting change, and away from the things that give almost no feedback for weeks and then actually work.

I've had patients arrive with bad acne having done hydration intensively for years. Years of masks and essences and layering, on skin with active inflammatory acne that had never been treated.

This needs to stop, and I say that as strongly as I say anything on this website. Hydration is not acne treatment. If your routine consists of hydrating products and nothing that addresses the acne process, you have a pleasant routine, not a treatment.

5. Quitting before it's had a chance

The Clear phase takes around three months.

Not because we're being cautious, but because that's the skin's own timeline, and because the actives are being titrated up gradually rather than applied at full strength on day one — which is deliberate, since escalating too fast produces irritation, and irritation is what makes people quit.

So there's a stretch — roughly weeks two to six — where you're on treatment, your skin isn't dramatically better, and it may be slightly irritated from the escalation. That's the window where most people abandon a programme that was working.

Give it three months before you judge it.

And if it's irritating you, tell me rather than quitting silently. Irritation means we're climbing faster than your skin will take, and adjusting the titration is straightforward if I know about it. What I can't do anything about is a patient who stops and doesn't say.

The same applies to the phases after. Fade takes another three months. And maintenance is ideally ongoing, or at least a year before we trial stopping. Clearing your skin and stopping everything is the cycle you've probably already been through several times — that's what maintenance exists to break.

And two more, quickly

Over-washing and over-treating. When skin is oily and breaking out, the instinct is to strip it — harsh cleansers, multiple washes, scrubbing, and stacking every active you own. That damages the barrier, produces irritation, and irritation contributes to the very marks you'll spend the Fade phase treating. Clean, don't strip.

Stopping topicals the moment it's clear. Same error as the maintenance point, but worth its own line because it's so common. Clear skin is the treatment working, not the treatment finishing.

The thread through all of these

Acne rewards structure and patience, and almost every mistake on this list is a substitute for one or the other.

Social media offers speed. Products offer the feeling of doing something. Ten-step routines offer effort as a proxy for progress. Hydration offers instant feedback. Quitting early is impatience with a timeline nobody explained.

The actual answer is unglamorous: the right actives, titrated up properly, given three months, then three more, then maintained. Plus sunscreen, no popping, and finding your real food trigger once things are quiet enough to test.

That's it. It's not exciting, and it works.

简要说明

我是陈医生，亚庇 Lintas Square 的 Klinik Dr Tan（皮肤与暗疮）。这是陷阱清单，不是指责。

1. 相信未经验证的来源

社交媒体上的护肤建议是一个非常庞大的产业，而且几乎不需要对任何人负责。

推荐东西给你的人通常没有检查过任何一位病人，无从得知你的皮肤实际状况，而且——这一点最常被忽略——他们展示的成果，往往来自他们推荐的东西以外的其他治疗。一个靠处方药维持皮肤干净的人，在卖你一瓶精华。

这还没算更基本的问题：你看到的是经过筛选的样本——有效的那些人、在有效的那段时间发文、用他们挑好的光线。

我不会叫你不要用社交媒体。但对你在上面看到的东西，我会用一个测试：如果这个东西不能卖钱，这个人还会推荐它吗？

2. 不理解「产品」和「药物」的差别

这是这一页最有用的区分，而且适用范围远超痘痘。

药物含有已被证实有效的成分。 这正是它们受管制、往往需要处方的原因——因为强到足以真正改变你皮肤行为的东西，用错了也足以造成问题。管制的存在是因为成分有效，不是尽管它有效。

产品多数未经证实。 而我希望你好好想想这一句：即使是那些经过证实的，和药物相比效益也是「边际」的。

不是零。是边际。

这不是对护肤品的傲慢，这是关于「效果量级」的陈述。配方良好的产品可能带来小小的差别；而一套逐步加量的过氧化苯甲酰＋杜鹃花酸＋A 酸，会改变你皮肤在做的事。

所以当有人花了三年和不少钱不断换产品、痘痘却毫无改变——那不是因为他选错了产品，而是因为他从头到尾都在错的类别里操作。

如果整个类别产生的都是边际效益，那么在这个类别里再怎么找，也找不到一个大的。

3. 相信你需要十个步骤的保养流程

十步骤流程很流行、行销很多，而且多数是不必要的。

给出的理由通常关于**「修复屏障」**——说你的屏障受损了，需要一套繁复的产品序列来修复。

屏障确实重要。但屏障是靠「不去破坏它」修复的，远大于靠「往上面涂七样东西」。 少用刺激性洗面乳、少搓、少过度清洁，以及不要在没有监督的情况下把多种活性成分层层叠加。

而繁复流程在痘痘上有一个具体的问题：步骤越多，刺激的机会越多，而且堆叠里有东西在对抗你的活性成分的机率也越高。 我经常遇到十步骤流程里有三样根本不该在那里的病人，底下的痘痘治疗从来没有机会发挥。

真正有效的其实很简单：温和的洗面乳、你的活性成分、防晒，需要的话加一个保湿。就这样。 多出来的东西需要一个理由，而不只是一段关于屏障修复的行销叙事。

还有一点值得说破：繁复之所以受欢迎，部分正是因为它繁复。 十个步骤感觉像是「有努力」，而努力感觉上应该要有成果。并不一定。

4. 保湿迷思

这一项值得单独一段，因为它是过去十年最成功的护肤行销。

保湿被卖成万能答案——痘痘、色素、皱纹，每个问题，同一个解法。

保湿确实重要，我没有否定它。但它被抬到远超过它实际作用的位置，而背后的机制是这样的：

保湿会产生快速、看得见的效果。 敷一片面膜，马上就看得到差别——更饱满、更平滑、更好看。

然后几个小时后，它就没了。

那就是全部的现象。 那是含水量带来的暂时性外观效果，不是皮肤功能的改变。

现在想想为什么产业这么喜欢它。它快，所以感觉有效。它是暂时的，所以可以重复——也就是重复购买。而且它对制造商几乎零风险，不像活性成分——那些真的有效，但会造成刺激，因而带来投诉。

所以有一套商业逻辑在把你推向「立即回馈、没有持久改变」的东西，并把你推离「好几周都几乎没有回馈、然后真的有效」的东西。

我遇过带着严重痘痘来的病人，已经密集做了好几年的保湿。 好几年的面膜、精华、层层叠加，而底下是从来没有被治疗过的活跃发炎性痘痘。

这件事需要停止，而我说这句话的力道，和我在这个网站上说过的任何一句一样重。保湿不是痘痘治疗。如果你的流程由保湿产品组成，而没有任何东西在处理痘痘的过程，那你有的是一套愉快的流程，不是治疗。

5. 在它有机会之前就放弃

清除期大约需要三个月。

不是因为我们保守，而是因为那是皮肤自己的时间表，而且因为活性成分是逐步加量的，不是第一天就全力上——这是刻意的，因为加太快会造成刺激，而刺激正是让人放弃的原因。

所以会有一段时间——大约第二到第六周——你在用药、皮肤没有明显变好、而且可能因为加量而有点受刺激。那正是多数人放弃一个原本有效的疗程的时间窗口。

请给它三个月再评价。

而如果它在刺激你，请告诉我，不要默默放弃。 刺激代表我们爬升的速度超过你皮肤能承受的，而只要我知道，调整加量的速度是很简单的事。我唯一没办法处理的，是停药却不说的病人。

后面的阶段也一样：淡化期再三个月，维持最好是持续的，或至少一年后再试着停。皮肤清了就全部停掉，正是你大概已经经历过好几次的循环——维持的存在就是为了打断它。

再快速补两个：过度清洁与过度治疗（皮肤出油又冒痘时，直觉是把它「洗掉」——刺激性洗面乳、洗好几次、搓、把手上所有活性成分都叠上去。那会破坏屏障、造成刺激，而刺激又会造成你之后要花整个淡化期去处理的痘印。清洁，不要剥夺。）；一好转就停掉外用药（皮肤清了是治疗在起作用，不是治疗结束了。）
