Acne scars that stayed after the acne cleared
Most of what people call acne scars are not scars. They are flat marks — red, purple or brown — left in skin that has healed. They behave completely differently from real scarring, they respond to different things, and a large share of them fade on their own if nothing makes them worse.
So the first question is not which treatment. It is whether the surface of your skin is smooth or not. That single answer sorts almost everything that follows.
The test that sorts it, and it takes ten seconds
Stand at a window, side-on to the light, and look at your face in a hand mirror from an angle rather than straight on. Then do the same under an overhead light.
- If the marks disappear when the light is flat and only the colour remains, you are looking at pigment or lingering redness. The skin surface is intact. This is not scarring.
- If you can see dents, pits or a rolling unevenness that changes as the light angle changes, there is texture change. That is scarring, and it is a different conversation.
- If it is both — which is common — then they are two separate problems that happen to live on the same face, and they should be planned separately.
Photographs taken with a flash flatten everything and are the worst possible way to make this judgement. Side light is the honest light.
The three things people call acne scars
| What it looks like | What it actually is | What that means |
|---|---|---|
| Flat red or purplish patches where spots used to be, more visible after exercise or a hot shower | Lingering redness in healed skin, sometimes called post-inflammatory erythema | Usually fades over months on its own; there are treatments aimed at redness — see post-acne redness |
| Flat brown or grey-brown marks, often darker on deeper skin tones, worse after sun | Post-inflammatory pigmentation | Fades slowly, and sun exposure is the single biggest thing that slows it — background at hyperpigmentation |
| Small deep pits, sharp-edged square depressions, or a soft undulating unevenness | True atrophic scarring — ice pick, boxcar and rolling, respectively | Does not fade with time; this is where treatment is the only route — see acne scars |
There is a fourth, less common one: raised, thickened scars. Those behave differently again and are worth having looked at rather than guessed about.
Why the distinction changes what you do next
Because the two categories fail in opposite directions.
Flat marks punish impatience. They are already healing. The main way people make them worse is by attacking them — strong actives stacked on top of each other, aggressive scrubbing, repeated irritation — which restarts the inflammation that caused the mark in the first place. A pigment mark treated harshly can end up darker than it started.
Texture change punishes patience. Atrophic scarring does not resolve on its own. Waiting three years to see whether it settles is three years spent not treating it. If there are dents, the useful question is what to do, not whether to wait.
This is also why a single generic answer to “what do I do about my acne scars” is nearly always wrong for half the people asking it.
How long each one actually takes
- Redness. Often months. It is common for it still to be visible at six months and gone by twelve, and it is genuinely hard to be patient with because it is the most visible one under bad lighting.
- Pigmentation. Months to well over a year, and the timeline is heavily influenced by sun. Consistent daily protection is not a wellness suggestion here; it is the difference between fading and not.
- Atrophic scarring. Indefinite. It changes with treatment or it does not change. Sessions are measured in months and courses rather than single visits — the sessions-and-results framing is set out at post-acne marks and sessions.
Four ways people make it worse while waiting
- Sun, without protection. The most avoidable factor in how long a pigment mark stays, and the one most consistently ignored between October and April.
- Continuing to pick. Every new picked spot resets the clock and adds a mark to a face that is already waiting for marks to fade. The mechanism is covered in dark marks after picking.
- Stacking strong products. Three actives from three different sources, applied together to skin that is still calming down, buys irritation rather than speed.
- Treating the marks while the acne is still active. If new spots are still forming, they will produce new marks. Settling the acne comes first; there is no version of this where it does not.
What a consultation should actually tell you
Come away with four answers: whether what you have is pigment, redness, texture change, or a combination; whether your acne is settled enough for it to be worth treating the aftermath at all; roughly how many sessions of what, over what period; and what result is plausible rather than what is possible in a best case.
Be wary of an answer that arrives before anyone has looked at your skin under proper light and at an angle. Be equally wary of a single treatment offered for everything, because these are not one problem. Skin tone matters here too: the risk profile of some approaches differs on deeper skin, and a clinic should raise that with you rather than wait for you to ask. The comparison of the two main routes for real scarring is laid out at acne scar treatment.
When it is a doctor’s job first
If acne is still active and producing new lesions, especially deep or cystic ones, treating scarring is premature and a doctor is the right first stop. Effective medical treatments exist, and the window in which they prevent further scarring does not stay open indefinitely. The same applies if scars are raised and thickened rather than depressed, or if you are unsure whether what you are looking at is scarring at all.
If the acne itself has not settled, start there instead — what causes acne is the better entry point, and for a teenager still in it, what a parent should book first.

Frequently asked questions
How do I know if I have acne scars or just marks?
Look at your skin side-on to a window rather than straight into a flat light. If only colour remains and the surface is smooth, it is pigment or lingering redness rather than a scar. If you can see dents or a rolling unevenness that shifts as the light angle changes, that is texture change, which is true scarring.
Will acne marks fade on their own?
Flat red and brown marks usually do, over months and sometimes over a year. True atrophic scarring — pits, sharp-edged depressions, rolling unevenness — does not fade with time, which is why telling the two apart matters before deciding to wait.
Why are my marks getting darker instead of lighter?
The two usual reasons are sun exposure without protection, and irritation from treating the marks too aggressively. Strong actives stacked on skin that is still calming down can restart the inflammation that caused the mark, and a pigment mark handled harshly can end up darker than it started.
Should I treat scarring while I still have active acne?
Generally not. New lesions produce new marks, so treating the aftermath while the cause is still running rarely holds. Settling the acne comes first, and if it is deep or cystic that is a doctor’s job rather than a clinic’s.
How many sessions does acne scarring take?
It is measured in courses over months rather than single visits, and the honest number depends on the type and depth of the scarring and on your skin. A consultation should give you a plausible range and a plausible result, not a best case.
General information about marks and scarring left after acne. It is not medical advice, it is not a diagnosis, and no result is promised or implied. Active acne, deep or cystic lesions, raised or thickened scars, or uncertainty about what you are looking at should be assessed by a doctor. Whether a treatment suits you depends on your skin, your skin tone, your health and your history, and that is a judgement for a qualified professional at a consultation.
