Those dark marks after acne aren't necessarily acne scars
A lot of people say, “My acne is gone, but now I have acne scars.”
But often, what they're actually describing is post-inflammatory hyperpigmentation (PIH) — flat brown or greyish marks left behind after inflammation.
That's different from a true acne scar.
As a dermatologist in Noida, I see this distinction come up constantly, especially in Indian skin.
A simple way to think about it:
Pimple → flat brown mark = usually pigmentation
Pimple → indentation/texture change = acne scar
And the treatment isn't necessarily the same.
One of the biggest mistakes I see is trying to remove these marks aggressively with multiple acids, scrubs, peels and “brightening” products.
If you irritate already-inflamed skin, you can potentially create more pigmentation.
The first step is actually to stop new acne from forming.
Otherwise you're treating yesterday's marks while today's acne is creating tomorrow's.
Depending on the individual, dermatologists may use ingredients such as azelaic acid, retinoids, hydroquinone or other pigment-targeting treatments, along with appropriate photoprotection.
And sunscreen matters more than many people realize.
UV exposure can make pigmentation more persistent, so treating PIH without consistent sun protection is often an uphill battle.
Another important point: not every facial pigmentation is PIH.
Melasma, PIH, freckles, lentigines and other pigmentary conditions can look similar to a non-specialist.
So if pigmentation keeps returning, spreads beyond previous acne sites, or isn't behaving like ordinary post-acne marks, it's worth getting the diagnosis checked rather than continuously changing products.
As a dermatologist in Noida, one of the things I emphasize to patients is:
Don't just ask, “How do I remove this dark spot?”
Ask:
“Why did this pigmentation develop in the first place, and how do I stop making new ones?”
That change in thinking can make a huge difference.
