Acne marks vs acne scars comparison with QTWAYS Niacinamide, Kojic Acid & Vitamin B5 Face Serum explaining the difference, causes, and clinically proven treatment for clearer skin.

Acne Marks vs Acne Scars: What's the Difference and How to Treat Them?

June 29, 2026

If you've ever looked in the mirror after your acne healed and wondered whether the leftover spot is an acne mark or an acne scar, you're not alone. Many people use these terms interchangeably, but they're actually two completely different skin concerns.

Understanding the difference is important because the right treatment depends on what you're dealing with. While most acne marks respond well to skincare ingredients like Niacinamide, Kojic Acid, Vitamin C, and Alpha Arbutin, true acne scars involve damage beneath the skin and often require professional treatments such as microneedling or laser resurfacing.

In this guide, we'll explain:

The difference between acne marks and acne scars.
How to identify each one.
Why they happen.
Which treatments actually work.
When skincare is enough and when it's time to visit a dermatologist.

Acne Marks vs Acne Scars: Quick Comparison

Feature	Acne Marks	Acne Scars
Appearance	Brown, red, pink, or purple spots	Indented or raised skin
Texture	Completely flat	Uneven, pitted, or raised
Cause	Pigmentation or damaged blood vessels	Collagen damage during healing
Pain	No	No
Can fade naturally?	Usually yes	Rarely
Responds to skincare	✅ Yes	Limited
Professional treatment required	Sometimes	Often

Quick Tip: If your skin feels completely smooth when you run your fingers over it, it's most likely an acne mark. If you feel a pit, dip, or raised bump, it's probably an acne scar.

What Are Acne Marks?

Acne marks are flat areas of discoloration left behind after a pimple heals. Unlike acne scars, they don't change your skin's texture—they only affect its colour.

These marks appear because inflammation during acne triggers changes in melanin production or temporarily damages tiny blood vessels near the skin's surface.

The good news is that acne marks are usually temporary and often improve with consistent skincare and daily sun protection.

Types of Acne Marks

Post-Inflammatory Hyperpigmentation (PIH)

PIH appears as:

Brown spots
Dark brown patches
Black marks

This happens when inflammation stimulates melanocytes to produce excess melanin during the healing process.

PIH is particularly common in Indian and melanin-rich skin tones.

If you'd like to understand this condition in detail, read our guide on Post-Inflammatory Hyperpigmentation (PIH) Explained.

Post-Inflammatory Erythema (PIE)

PIE appears as:

Pink marks
Red spots
Purple discoloration

Unlike PIH, PIE isn't caused by extra pigment. Instead, it's the result of tiny blood vessels remaining dilated after inflammation.

PIE is generally more common in fair skin tones and may take longer to fade than expected.

What Are Acne Scars?

Acne scars develop when severe inflammation damages the skin's collagen during the healing process.

Instead of leaving behind a simple colour change, the skin heals unevenly, creating permanent changes in texture.

This is why acne scars cannot usually be removed using skincare products alone.

Dermatologists classify acne scars into two main categories:

Atrophic (Indented) Scars
Hypertrophic or Keloid (Raised) Scars

Understanding which type you have is essential before choosing a treatment.

Types of Acne Scars

Ice Pick Scars

These are deep, narrow scars that extend into the skin.

They often resemble tiny pinholes and are considered one of the most challenging acne scars to treat.

Dermatologists commonly recommend procedures such as TCA CROSS or laser treatments.

Boxcar Scars

Boxcar scars are wider, round or oval depressions with well-defined edges.

These scars often respond well to treatments such as:

Microneedling
Fractional Laser Resurfacing
Chemical Peels (selected cases)

Rolling Scars

Rolling scars create a wave-like appearance because fibrous bands pull the skin downward.

They usually require procedures such as:

Subcision
Microneedling
Laser therapy
Dermal fillers (in selected cases)

Raised (Hypertrophic or Keloid) Scars

Instead of losing collagen, these scars develop because the skin produces too much collagen during healing.

They appear as raised bumps above the skin surface and usually require dermatologist-guided treatment.

How to Tell If You Have Acne Marks or Acne Scars

One of the easiest ways to identify them is the Finger Test.

If your skin feels completely smooth...

You most likely have acne marks.

These respond well to skincare ingredients that target pigmentation and support skin renewal.

If you can feel a depression or raised bump...

You most likely have an acne scar.

Because collagen has already been damaged, topical skincare alone usually won't provide significant improvement.

In these cases, professional treatments are often recommended.

Key Takeaways

Acne marks affect skin colour, while acne scars affect skin texture.

Most acne marks fade gradually with the right skincare routine.

Acne scars involve collagen damage and often require dermatologist treatments.

Identifying your skin concern correctly helps you choose the most effective treatment instead of wasting time and money on unsuitable products.

Can Acne Marks Turn Into Acne Scars?

This is one of the most common questions people ask after a breakout.

The short answer is no.

Acne marks and acne scars are two different conditions. An acne mark does not gradually "turn into" an acne scar over time. Instead, acne scars develop during the healing process when inflammation damages the skin's collagen.

For example:

A mild pimple may heal and leave behind a flat brown mark (Post-Inflammatory Hyperpigmentation or PIH).
A severe, inflamed cyst may damage collagen while healing, resulting in an indented acne scar.

This is why treating inflammatory acne early is one of the most effective ways to reduce the risk of permanent scarring.

Best Treatments for Acne Marks

Since acne marks affect skin colour rather than skin texture, they often respond well to topical skincare.

The most effective treatment depends on whether you're dealing with brown pigmentation (PIH) or red marks (PIE).

Clinically Proven Ingredients for Brown Acne Marks (PIH)

Niacinamide

Niacinamide is one of the most researched ingredients for post-acne pigmentation.

It works by reducing the transfer of melanin to skin cells while strengthening the skin barrier.

Benefits include:

Helps reduce post-acne pigmentation.
Supports skin barrier repair.
Controls excess oil.
Helps reduce inflammation.

If you have oily or acne-prone skin, Niacinamide is often one of the best ingredients to include in your daily routine.

Kojic Acid

Kojic Acid is a well-known tyrosinase inhibitor that helps reduce excess melanin production.

It is particularly effective for stubborn brown acne marks that remain after breakouts.

Benefits include:

Helps fade post-acne pigmentation.
Improves uneven skin tone.
Targets dark spots caused by acne.

Vitamin C

Vitamin C is a powerful antioxidant that helps brighten dull skin and improve overall skin tone.

While it may not be the strongest ingredient for stubborn pigmentation, it works well alongside ingredients like Niacinamide and Kojic Acid.

Benefits include:

Brightens skin.
Helps improve uneven skin tone.
Protects against environmental damage.

Alpha Arbutin

Alpha Arbutin is a gentle brightening ingredient that slows excess melanin production without being overly irritating.

It is often recommended for people with sensitive skin who want gradual improvement in pigmentation.

Retinoids

Retinoids increase skin cell turnover, allowing pigmented skin cells to shed more quickly.

They are also useful for preventing future breakouts, making them valuable for people dealing with both acne and post-acne marks.

Best Ingredients for Red Acne Marks (PIE)

Red acne marks are caused by inflammation and damaged blood vessels rather than excess pigment.

Ingredients commonly recommended include:

Azelaic Acid
Niacinamide
Gentle Retinoids
Tranexamic Acid

Although PIE often fades naturally, it can take several months depending on your skin type and the severity of inflammation.

Which Treatment Works Best?

Skin Concern	Recommended Treatment
Brown Acne Marks (PIH)	Niacinamide, Kojic Acid, Vitamin C, Alpha Arbutin
Red Acne Marks (PIE)	Azelaic Acid, Niacinamide, Tranexamic Acid
Mild Uneven Skin Tone	Vitamin C, Niacinamide
Active Acne + Marks	Retinoids, Azelaic Acid, Niacinamide

Choosing the Right Serum for Acne Marks

Many people focus on finding a serum with just one active ingredient.

However, dermatologists often recommend formulas that combine multiple clinically studied ingredients because acne marks develop through more than one biological pathway.

For example:

Niacinamide helps reduce pigment transfer while strengthening the skin barrier.
Kojic Acid helps reduce excess melanin production.
Vitamin B5 helps soothe the skin.
Sodium Hyaluronate helps maintain hydration and reduce dryness caused by active ingredients.

Instead of relying on a single ingredient, choosing a multi-active formulation may provide a more comprehensive approach to post-acne pigmentation.

The QTWAYS 10% Niacinamide + 1% Kojic Acid Face Serum combines Niacinamide, Kojic Acid, Vitamin B5 and hydrating ingredients in a lightweight formula designed for acne-prone skin. It is formulated to help improve post-acne pigmentation and uneven skin tone while supporting the skin barrier.

Best Treatments for Acne Scars

Unlike acne marks, acne scars involve structural damage beneath the skin.

Topical skincare products can improve overall skin health, but they generally cannot rebuild lost collagen or completely smooth deep scars.

Dermatologists may recommend the following procedures depending on the type of acne scar.

Acne Scar Type	Common Dermatologist Treatment
Ice Pick Scars	TCA CROSS, Fractional Laser
Boxcar Scars	Microneedling, Laser Resurfacing
Rolling Scars	Subcision, Microneedling
Raised Scars	Steroid Injections, Laser Therapy

The most suitable treatment depends on the severity, scar type and individual skin condition.

Common Mistakes That Delay Improvement

Many people unintentionally slow down the healing process by following incorrect skincare practices.

Some of the most common mistakes include:

Picking or squeezing pimples.
Skipping sunscreen during the day.
Using multiple exfoliating acids in the same routine.
Expecting overnight results.
Stopping treatment too early.

Most clinically proven ingredients require consistent use for several weeks before visible improvements become noticeable.

How Long Does It Take to See Results?

Concern	Typical Timeline
Fresh Acne Marks	6–12 Weeks
Moderate PIH	3–6 Months
Red Acne Marks (PIE)	3–6 Months
Acne Scars	Usually require professional treatments

Individual results vary depending on skin type, the severity of acne, and consistency with skincare and sun protection.

How to Prevent Acne Marks and Acne Scars

Although acne marks and acne scars require different treatments, both are largely preventable if acne is managed correctly from the beginning.

Treat Acne Early

Inflammatory acne is more likely to leave behind pigmentation or scars. Starting an effective skincare routine as soon as breakouts appear can reduce the risk of long-term skin changes.

Avoid Picking or Popping Pimples

Picking acne is one of the leading causes of post-inflammatory hyperpigmentation and acne scars.

When you squeeze a pimple, you increase inflammation and push bacteria deeper into the skin, making collagen damage more likely.

Wear Sunscreen Every Day

Ultraviolet (UV) exposure stimulates melanin production, making acne marks darker and more noticeable.

A broad-spectrum sunscreen with SPF 30 or higher should be applied every morning, regardless of the weather.

Daily sun protection also helps prevent existing pigmentation from becoming more persistent.

Maintain a Healthy Skin Barrier

Using too many exfoliating acids or harsh scrubs can weaken the skin barrier, increasing irritation and delaying healing.

A balanced routine that includes hydration and barrier-supporting ingredients is more effective than using multiple strong actives together.

Be Consistent With Your Skincare Routine

Most brightening ingredients require regular use for several weeks before noticeable improvements occur.

Switching products every few weeks often prevents you from seeing meaningful results.

When Should You Visit a Dermatologist?

While most acne marks can be managed with skincare, professional treatment may be necessary in certain situations.

Consider consulting a dermatologist if:

Your acne marks have not improved after several months of consistent skincare.
You have deep, pitted, or raised acne scars.
Active acne continues to cause new marks.
Your pigmentation appears to be getting darker despite treatment.
You are unsure whether you have acne marks, acne scars, or another skin condition.

A dermatologist can recommend treatments such as prescription retinoids, chemical peels, microneedling, laser resurfacing, subcision, or TCA CROSS depending on your skin concern.

Frequently Asked Questions

Are acne marks and acne scars the same?

No. Acne marks are flat areas of pigmentation or redness that develop after acne heals. Acne scars are permanent changes in skin texture caused by collagen damage.

How can I tell if I have acne marks or acne scars?

A simple way to identify them is by touching your skin. If the area feels smooth, it is likely an acne mark. If you can feel a depression or raised bump, it is more likely an acne scar.

Can acne marks disappear naturally?

Yes. Most acne marks gradually fade over time, although the process can take several weeks or months depending on the severity and your skincare routine.

Are acne scars permanent?

Acne scars are generally considered permanent because they involve structural changes to the skin. However, dermatologist treatments can significantly improve their appearance.

Which is easier to treat: acne marks or acne scars?

Acne marks are generally much easier to treat because they affect skin colour rather than skin texture.

Can Niacinamide remove acne marks?

Niacinamide is one of the most widely recommended ingredients for post-acne pigmentation. It helps reduce pigment transfer, strengthens the skin barrier, and supports a more even skin tone.

Does Kojic Acid work for acne marks?

Yes. Kojic Acid helps reduce excess melanin production and is particularly effective for brown acne marks caused by post-inflammatory hyperpigmentation.

Can serums remove acne scars?

Topical serums may improve overall skin health, but they cannot rebuild lost collagen or completely remove deep acne scars.

Which dermatologist treatments work best for acne scars?

The most commonly recommended treatments include microneedling, fractional laser resurfacing, TCA CROSS, subcision, and, in some cases, dermal fillers.

Does sunscreen help acne marks fade?

Yes. Sunscreen helps prevent UV-induced pigmentation and allows brightening ingredients to work more effectively.

Key Takeaways

Acne Marks	Acne Scars
Flat discoloration	Structural skin damage
Brown, red or pink	Indented or raised
Usually fade over time	Usually require professional treatment
Respond well to skincare	Respond better to clinical procedures
Can improve with Niacinamide and Kojic Acid	May require microneedling, laser or subcision

Conclusion

Although acne marks and acne scars often look similar, they are fundamentally different skin concerns that require different treatment approaches.

Acne marks are temporary changes in skin colour caused by inflammation. They commonly appear as brown, red, or pink spots and often improve with clinically proven ingredients such as Niacinamide, Kojic Acid, Vitamin C, Alpha Arbutin, and Retinoids, combined with daily sunscreen and a consistent skincare routine.

Acne scars, on the other hand, develop when inflammation damages the skin's collagen. Because they involve structural changes beneath the skin, they usually require dermatologist-performed procedures such as microneedling, laser resurfacing, subcision, or TCA CROSS.

If your concern is post-acne pigmentation rather than textural scarring, choosing a serum formulated with clinically studied brightening ingredients can support a more even-looking complexion. The QTWAYS 10% Niacinamide + 1% Kojic Acid Face Serum combines two well-researched ingredients for post-acne pigmentation with barrier-supporting and hydrating actives, making it a suitable option for people looking to improve flat acne marks while maintaining skin comfort.

The first step toward choosing the right treatment is identifying whether you have an acne mark or an acne scar. Once you understand the difference, you can build a skincare routine that addresses your skin's specific needs instead of relying on treatments that may not be appropriate for your concern.
