Acne Marks vs Acne Scars: How to Tell the Difference and Treat Each
If you have had acne, you have probably looked in the mirror after the spots settle and wondered: are these scars, or will they fade? It is one of the most common questions we hear at Dr Jane Clinic, and the answer matters, because acne marks and acne scars are different problems with different treatments.
Many people search for "acne scar removal" when what they actually have are flat marks that respond well to gentler treatment. Others spend months on brightening creams for scars that only a procedure can improve. This guide explains how to tell them apart, what causes each, and how a doctor decides what will help.
What Is the Difference Between Acne Marks and Acne Scars?
The simplest way to think about it is colour versus texture.
Acne marks are flat. They change the colour of your skin (brown, dark, pink or red) but the surface feels smooth when you run a finger over it.
Acne scars change the texture of your skin. They are dents, pits or raised areas left behind when deep inflammation damaged the collagen underneath.
You can have both at the same time, which is very common. A good assessment separates the two so each is treated properly.
The Two Types of Acne Marks
1. Dark or brown marks (post-inflammatory hyperpigmentation)
After a pimple heals, the skin can produce extra pigment in that spot, leaving a brown or dark mark. This is called post-inflammatory hyperpigmentation, or PIH. It is especially common in Asian and darker skin tones, so it is something we see every day in Malaysia.
Dark marks often fade gradually on their own, but this can take many months, and sun exposure, picking or squeezing pimples can make them darker and longer-lasting.
2. Red or pink marks (post-inflammatory erythema)
Some marks stay red or pink rather than brown. This is post-inflammatory erythema, or PIE, sometimes simply called acne redness. It comes from small blood vessels that have become dilated in the healing skin, not from pigment, which is why brightening products that target pigment often do little for it.
A quick check: gently press a clear glass over the mark. If the red colour fades under pressure, it is likely PIE. A brown mark that does not change is more likely PIH.
The Main Types of Acne Scars
True acne scars sit in or below the skin surface. The three types most people have are:
Ice pick scars: narrow, deep pits
Boxcar scars: wider depressions with sharper edges
Rolling scars: broad, shallow dips that give the skin a wavy look
We cover these in detail, with which treatment suits each type, in our guide to acne scar types: ice pick, rolling and boxcar scars.
How to Tell Which One You Have
A few simple clues at home:
Run your finger over it. Smooth means a mark. A dip or bump means a scar.
Look in side lighting. Stand by a window or use your phone torch from the side. Scars cast small shadows; flat marks do not.
Notice the colour. Brown suggests PIH, red or pink suggests PIE. Scars can be skin-coloured, or have colour on top.
Think about time. Marks tend to lighten slowly over months. Indented scars do not fill in by themselves.
These checks are a useful starting point, but they are not a diagnosis. Under good lighting, a doctor can also spot early scarring hidden under pigment, and tell whether active acne is still creating new marks.
How Acne Marks Are Treated
The good news is that acne marks are usually the more treatable of the two, and often need less downtime.
For dark marks (PIH)
Pico laser: ultra-short laser pulses break up excess pigment. At Dr Jane Clinic we use the Discovery Pico Laser, which is suitable for Asian skin, and pigmentation treatments generally involve little or no downtime. Learn more on our Pico laser page.
Chemical peels and medical skincare: to encourage cell turnover and even out tone, chosen to suit your skin.
Daily sunscreen: without sun protection, dark marks are much slower to fade and can return.
Our pigmentation treatment page explains how we approach dark spots and uneven tone more broadly.
For red marks (PIE)
Vascular laser: targets the small blood vessels behind persistent redness. See our vascular laser treatment page.
Pico laser: can be combined for redness that sits alongside pigment.
Topical medical creams: may help milder redness.
How Acne Scars Are Treated
Because scars involve damaged collagen, they need treatments that remodel the skin or lift depressed areas. Depending on the scar type, options at our clinic include:
Microneedling (SkinPen): often used for rolling and textural scars
Pico laser: for shallow scars, especially with pigmentation on top
Fractional CO2 laser: a stronger option for deeper scars, with a longer recovery
Punch excision: for stubborn ice pick scars
Dermal fillers: to lift certain depressed scars
Most people with scarring do best with a combination plan over several sessions. Our acne scar treatment page walks through each option and what recovery looks like.
Why Controlling Active Acne Comes First
Treating marks or scars while breakouts continue is like repainting a wall that is still leaking. Every new inflamed spot can leave a new mark, and deep, cystic acne is what causes most scarring. If you are still breaking out, the first step is getting acne under control with the right mix of skincare, medication, facials or procedures. Our acne treatment page and our article on acne facial vs laser vs medication explain the options.
Realistic Expectations
It is worth being honest about what treatment can and cannot do:
Marks often improve noticeably, but they fade gradually rather than overnight, and sun protection is part of keeping results.
Scars can be improved, often significantly, but rarely erased completely. The aim is smoother, more even skin you feel confident in.
Results depend on your skin type, how deep the marks or scars are, and how consistently you follow aftercare.
A plan built around what you actually have, rather than what you assume you have, is usually faster and kinder to your skin.
Frequently Asked Questions
Will acne marks go away on their own?
Many flat dark or red marks do fade with time, especially with daily sunscreen and no picking, but it can take months. Treatment can speed this up. Indented scars, however, do not fill in on their own.
Can the same laser treat both acne marks and acne scars?
Sometimes. Pico laser can help with pigmentation and shallow scars, which is useful when you have both. Deeper scars or persistent redness usually need other treatments as well, which is why an assessment matters.
Is it safe to treat acne marks on Asian skin?
Yes, with the right approach. Asian skin is more prone to pigmentation, so settings, treatment choice and aftercare need care. Our doctors tailor treatment to your skin type and always discuss sun protection and aftercare.
Not Sure Whether You Have Marks or Scars?
Our LCP-certified aesthetic doctors, Dr Jane Frances and Dr Huey Ming, can look at your skin in person, explain exactly what you are dealing with, and suggest a realistic plan, with no pressure to start anything you are not ready for.
