Acne Marks vs Acne Scars: What’s the Difference & How to Treat Them?
A pimple may disappear within days, but the spot or uneven texture it leaves behind can last much longer. Many people call every post-pimple spot an “acne scar,” but acne marks and acne scars are different. The easiest way to tell them apart is simple: acne marks mainly change skin colour, while acne scars change skin texture.
Knowing which one you have matters because treatment differs. Choosing the right acne marks treatment can help improve flat post-acne discoloration, while deep pitted or raised scars often need dermatologist-led care.
Acne Marks vs Acne Scars: Quick Difference
If the affected area is flat and appears brown, red, pink, or grey, it is more likely an acne mark caused by lingering pigmentation or redness. In contrast, if the skin has visible pits, dents, uneven waves, or raised areas, it is more likely to be a true acne scar.
Flat post-acne discoloration mainly affects skin colour, while true acne scars involve structural changes in the skin, such as depressions, uneven texture, or raised tissue.
What Are Acne Marks?
Acne marks are flat areas of discoloration that remain after a pimple heals. Unlike true acne scars, they usually do not create pits, dents, or raised skin. The affected area generally feels smooth, but the color may look different from the surrounding skin.
Two common types of acne marks are:
Post-Inflammatory Hyperpigmentation (PIH)
PIH appears as brown, dark brown, or greyish spots after acne inflammation. It develops when the skin produces excess melanin during the healing process and can be more noticeable or persistent in medium to deeper skin tones.
Post-Inflammatory Erythema (PIE)
PIE appears as red, pink, or purplish marks after an inflamed pimple heals. These marks are mainly linked with lingering redness in the skin.
A simple way to identify acne marks is by texture: the skin usually remains flat and smooth. They may gradually fade over time, but repeated breakouts, picking or squeezing pimples, and excessive sun exposure can make them darker or more persistent.
Post-inflammatory hyperpigmentation can be more noticeable and longer-lasting in darker skin tones.
What Are Acne Scars?
Acne scars are permanent or long-lasting structural changes in the skin that develop when deeper acne inflammation damages the skin tissue and affects collagen production during healing. Unlike acne marks, which mainly change skin color, true acne scars change the skin’s texture, depth, or contour.
Common types of acne scars include:
Ice Pick Scars: Deep, narrow, pin-point depressions that extend into the skin and often look like tiny holes.
Boxcar Scars: Wider, round or oval depressions with clearly defined edges. They may be shallow or deep.
Rolling Scars: Broad, shallow depressions that create an uneven, wave-like appearance across the skin.
Hypertrophic Scars: Raised scars caused by excess collagen forming during the healing process.
Keloid Scars: Raised scars that can grow beyond the original area of acne inflammation.
Unlike post-acne pigmentation, true acne scars usually do not disappear simply by using a brightening or pigmentation serum. The right treatment depends on the type and depth of the scar, skin tone, overall skin condition, and whether active acne is still present.

Why Do Pimples Leave Dark Marks on Indian Skin?
Post-inflammatory hyperpigmentation after acne is an important concern for Indian and other melanin-rich skin tones.
When acne becomes inflamed, pigment-producing cells can create additional melanin. Even after the pimple heals, some of this pigment may remain as a flat brown or grey-brown mark. These post-acne dark spots and pigmentation can be more noticeable in deeper skin tones and may become darker with UV exposure.
This makes preventing new breakouts equally important. Picking, squeezing, harsh scrubbing, and irritating skincare can increase inflammation and may increase the risk of dark spots after acne and scarring.
How to Treat Acne Marks
Flat pimple marks and dark spots generally respond better to skincare than true scars. Focus on controlling acne, protecting the skin and supporting a more even-looking complexion.
1. Use Sunscreen Every Day
Broad-spectrum SPF 30 or higher should be an important part of your acne marks routine. Sun exposure can make post-inflammatory pigmentation appear darker.
For acne-prone skin, choose a derma sunscreen labelled non-comedogenic or designed not to clog pores.
2. Add Niacinamide to Your Routine
Niacinamide for acne marks is popular because it can fit well into routines for oily, acne-prone and uneven-looking skin. A suitable niacinamide serum for acne can be combined with hydration, acne control and daily sun protection instead of layering several harsh active ingredients at once.
3. Consider Azelaic Acid
Azelaic acid for acne marks is another ingredient used for acne and post-inflammatory pigmentation. DermNet includes azelaic acid among topical options used for post-inflammatory hyperpigmentation.
If you have sensitive skin, introduce active ingredients gradually.
4. Use Salicylic Acid for Active Acne
Salicylic acid helps clear clogged pores and can be especially useful for oily and acne-prone skin. Using a 2% salicylic acid face wash as part of an acne-focused routine may help manage excess oil, clogged pores and recurring breakouts.
However, salicylic acid does not fill deep acne scars. Its main benefit here is controlling new acne, which may help reduce the chances of developing additional acne marks and scars.
5. Stop Picking or Squeezing Pimples
Picking a pimple can increase inflammation and tissue damage.
AAD specifically advises against popping or squeezing acne because it can make acne take longer to clear and increase the risk of both post-inflammatory hyperpigmentation and acne scarring.
How Are Acne Scars Treated?
The best acne scar treatment depends on the type of scar rather than following one treatment for everyone.
Depending on the individual case, dermatologist-led options may include:
- Microneedling
- Chemical peels
- Laser resurfacing
- Radiofrequency
- Fillers for selected depressed scars
- Acne scar surgery or other scar-specific procedures
AAD notes that dermatologists often create an individual treatment plan based on the scar type, number of scars, skin tone and other factors. Combination treatments may sometimes be used.
If you have ice pick, boxcar, rolling or raised acne scars, professional evaluation is more appropriate than relying only on home remedies or aggressive exfoliation.
Best Skincare Routine for Acne Marks and Acne-Prone Skin
A complicated 10-step routine is not necessary. Consistency matters more.
Morning Routine
- Gentle face wash
- Niacinamide or another suitable serum for dark spots
- Lightweight, non-comedogenic moisturiser
- Broad-spectrum sunscreen
Night Routine
- Gentle or acne-focused cleanser
- Targeted acne or pigmentation treatment
- Moisturiser to support the skin barrier
Dermasys offers concern-focused skincare options for acne-prone skin, dark spots, excess oil and uneven-looking skin tone. Choose products according to your skin type and introduce one active at a time instead of layering several strong ingredients together.
5 Mistakes That Can Make Acne Marks Worse
- Skipping sunscreen while treating dark spots
- Picking or squeezing pimples
- Scrubbing active or inflamed acne
- Combining too many acids and strong actives
- Treating old marks while ignoring active breakouts
When Should You See a Dermatologist?
Consider professional advice if you have painful or cystic acne, frequent breakouts, deep pits, raised scars or pigmentation that is not improving.
A dermatologist can determine whether you have PIH, post-acne redness, true acne scars or a combination and recommend treatment based on your skin.
Acne Marks vs Acne Scars: Final Takeaway
When comparing acne marks vs acne scars, remember one simple rule:
Colour = usually an acne mark. Texture = usually an acne scar.
Flat dark, brown, red or pink marks can often improve gradually with acne control, sun protection and suitable skincare. Pitted, indented or raised scars involve structural skin changes and may require professional treatment.
Instead of trying every trending acne product, first understand what your skin is showing. Control new breakouts, avoid picking pimples, use daily sun protection and choose skincare according to whether you are dealing with acne marks, pigmentation, active acne or true acne scars.

Frequently Asked Questions
Are acne marks and acne scars the same?
No. Acne marks are usually flat changes in colour, while acne scars change the texture or structure of the skin.
How do I know if I have acne marks or acne scars?
If the area feels smooth but looks darker, brown, red or pink, it is more likely an acne mark. A pit, dent or raised area is more suggestive of an acne scar.
Do acne marks go away naturally?
Many post-acne marks gradually fade, although some may remain visible for months or longer depending on pigmentation depth, skin tone and sun exposure.
Can acne scars go away on their own?
Established pitted or raised acne scars usually persist without treatment, although dermatologist-led procedures can make many scars less noticeable.
What ingredients can help acne marks?
Depending on your skin, ingredients such as niacinamide, azelaic acid and retinoids may be considered alongside daily sunscreen and acne control.
Does salicylic acid remove acne scars?
Salicylic acid can help manage clogged pores and active acne, but it cannot rebuild deep pitted acne scars.
Can niacinamide help acne marks?
Niacinamide can fit well into a skincare routine for uneven-looking tone, excess oil and post-acne marks.
Why are my acne marks getting darker?
Sun exposure, continued inflammation, picking and skin irritation can make post-inflammatory pigmentation appear darker or more persistent.
Can acne marks and acne scars occur together?
Yes. You can have flat pigmentation alongside ice pick, boxcar, rolling or raised acne scars on the same area of skin.
When should I see a dermatologist for acne scars?
Consult a dermatologist if your scars are deep, raised or widespread, if you have painful cystic acne, or if your current acne treatment is not improving your skin.
