Has a past breakout left an unwelcome souvenir on your skin? Those little reminders, often known as acne scars, can be frustrating, affecting not just our complexion but sometimes our confidence too. If you’ve ever looked in the mirror and wondered, “what are the causes of acne scars?” or “how to remove deep acne scars?”, you’re definitely not alone.
At Sky Skin and Laser Clinics, we get it. We believe everyone deserves skin they feel great in. This blog post is your comprehensive guide to understanding acne scars, from why they form to the fantastic ways we can now treat them. So, let’s dive in and demystify these pesky marks!
What Are Acne Scars?
Acne scars are permanent textural or pigmentation changes that occur on the skin as a result of severe acne inflammation. Basically, when a pimple goes rogue and damages your skin tissues, your body tries to heal it, and in that healing process, scar tissues may form. Depending on your skin type, genetics, and the type of acne, these scars can vary.
What are the types of Acne Scars?
Not all scars are created equal. Here’s a closer look at the different types of acne scars your skin might be dealing with:
Atrophic Scars (Most Common Type)
These are depressed scars that form when there’s a loss of tissue during the healing process. They’re further classified into:
1. Ice Pick Scars
- Small but deep, narrow holes that extend into the dermis.
- Look like open pores or tiny puncture wounds.
- Tough to treat due to their depth.
2. Boxcar Scars
- Wider than ice pick scars with sharp, defined edges.
- Often found on the cheeks and temples.
- Caused by inflammatory breakouts that destroy collagen.
3. Rolling Scars
- Shallow and wide with sloping edges, giving the skin a wavy, uneven texture.
- Form due to fibrous bands pulling the skin down beneath the surface.
Hypertrophic & Keloid Scars
These scars are the opposite of atrophic, raised instead of sunken.
1. Hypertrophic Scars
- Thick, raised scars that stay within the boundary of the original acne lesion.
- Caused by excess collagen production during healing.
2. Keloid Scars
- Similar to hypertrophic scars but grow beyond the original wound area.
- Can be itchy, painful, and more common in people with darker skin tones.
Post-Inflammatory Hyperpigmentation (PIH)
While technically not a scar, it’s worth mentioning because it lingers just as long.
Pigmentation Marks
- Flat spots of discoloration – red, brown, or purple, that remain after acne clears.
- Caused by melanin overproduction in response to inflammation.
- Can fade on its own but may benefit from brightening treatments.
What Causes Acne Scars and Dark Spots?
1. Inflammation and Skin Tissue Damage
- Overproduction or Underproduction of Collagen: Collagen is the skin’s natural “scaffolding.” When your body produces too little collagen after injury, it results in atrophic scars (sunken pits). On the flip side, too much collagen creates raised scars like hypertrophic or keloid scars.
2. Picking and Popping Pimples
We get it, the temptation is real. But squeezing or picking your pimples causes trauma to the skin and increases inflammation. This worsens the damage and can push bacteria deeper into the skin, increasing the risk of scarring.
- Increased Risk of Infection: Popped pimples can get infected, making scars more likely and pigmentation darker.
- Delays Healing: Constant touching interrupts the skin’s natural repair process.
3. Type of Acne
Not all acne is created equal. Certain types are more prone to cause scars:
- Cystic Acne Large, painful, pus-filled cysts buried deep under the skin cause severe inflammation and damage, leading to deep acne scars.
- Nodular Acne Hard, painful bumps that cause similar tissue destruction.
- These types often require aggressive acne scar treatment and sometimes medical intervention.
4. Delayed or Inadequate Treatment
Ignoring or improperly treating acne allows the inflammation to persist and worsen over time. The longer acne lesions stay on your skin, the more damage they can cause.
- Chronic Acne: Persistent acne breakouts increase the likelihood of developing scars.
- No Early Intervention: Early use of dermatologist-recommended treatments can reduce inflammation and prevent scars.
5. Genetics and Skin Type
Your genetic makeup influences how your skin heals. Some people naturally produce more collagen, making them prone to raised scars. Others might have skin that scars easily and takes longer to heal.
- Skin Color: Darker skin tones may develop more post-acne pigmentation and keloid scars.
6. Sun Exposure
- UV Rays Stimulate Melanin: The skin produces more melanin to protect itself, causing hyperpigmentation.
How Acne Causes Scars
Acne affects your skin’s deeper layers and can leave lasting marks. To truly understand how acne scars form, we need to look at the entire process your skin goes through when dealing with acne.
Step 1: Pore Blockage
Your skin is covered with tiny pores that release oil (sebum) to keep it moisturized. When dead skin cells, excess oil, and sometimes dirt clog these pores, it creates the perfect environment for bacteria to thrive. This blockage is the starting point for acne development.
Step 2: Bacterial Growth
Step 3: Inflammatory Response
Your immune system detects the bacterial overgrowth and floods the area with white blood cells to fight the infection. This battle causes redness, swelling, and pus formation, what you see as a pimple or zit.
- Mild Inflammation: Results in surface-level pimples like whiteheads or blackheads.
- Severe Inflammation: When the infection reaches deeper skin layers, it damages tissue, blood vessels, and collagen fibers.
Step 4: Pore Wall Rupture
If the inflammation is strong enough, the wall of the pore breaks open. This releases all the trapped debris, bacteria, dead skin cells, and oil, into surrounding skin tissue, causing even more inflammation.
- The depth of the rupture determines the severity of potential scarring.
- Shallow ruptures tend to heal with little to no scarring.
- Deep ruptures can cause significant tissue damage and scar formation.
Step 5: Healing and Collagen Production
Your skin begins the healing process by producing collagen, a key structural protein that helps repair damaged tissue.
- Too Little Collagen: Leads to depressed or atrophic scars, those sunken pits or dents on your skin.
- Too Much Collagen: Leads to raised scars, such as hypertrophic or keloid scars, where excess tissue builds up.
Step 6: Scar Formation
Because the skin’s repair system is imperfect, the collagen laid down during healing can be uneven or disorganized, leading to permanent scars.
- Atrophic Scars: Result from collagen loss and tissue damage, creating pits or depressions.
- Hypertrophic/Keloid Scars: Result from excessive collagen, causing thick, raised scars.

Symptoms of Acne Scars
Acne scars can show up in various forms, and recognizing these symptoms early can help you choose the right treatment approach. Here’s a closer look at how acne scars typically manifest on the skin:
1. Dents and Depressions on Cheeks or Forehead
- These are small to medium-sized indentations that make the skin surface appear uneven or pitted.
- Often described as “craters” or “holes,” they occur because the skin has lost collagen and tissue after severe inflammation.
- Most commonly found on the cheeks and forehead where acne tends to be more severe.
2. Bumpy or Raised Texture
- Some acne scars appear as raised, firm bumps on the skin.
- These are called hypertrophic or keloid scars and occur when the body produces too much collagen during healing.
- These scars may feel thick or rubbery to the touch and can sometimes extend beyond the original acne site.
3. Discoloration or Pigmentation Marks
- After acne heals, dark spots or patches often remain, this is called post-inflammatory hyperpigmentation (PIH).
- These marks can be red, brown, purple, or even pink depending on your skin tone and inflammation severity.
- Unlike scars, pigmentation marks are usually flat but can last for months or longer without treatment.
4. Uneven Skin Tone
- Acne scars and pigmentation can create blotchy or patchy areas on the skin.
- This unevenness disrupts the smoothness and uniformity of your complexion.
- It can make your skin look dull or aged, even when your acne has cleared.
5. Sensitivity Around Scar Tissue
- Scarred skin can sometimes feel tender or sensitive, especially when exposed to harsh skincare products, sun, or friction.
- Some scars may also cause mild itching or discomfort as the skin’s nerve endings can be affected during the healing process.
- This sensitivity can vary from person to person and may improve with proper care.
How to Avoid Acne Scars
Prevention is always better than cure when it comes to acne scars. Don’t wait until scars appear, start protecting your skin early with these key habits:
- Treat Acne Early: Use dermatologist-recommended products as soon as you notice breakouts. Early treatment reduces inflammation and minimizes skin damage that can lead to scarring.
- Never Pick or Pop Pimples: It’s tempting, but squeezing or picking at pimples causes trauma to the skin, increasing inflammation and the risk of permanent scars.
- Follow a Consistent Skincare Routine: A simple routine of cleansing, treating active acne, moisturizing, and protecting your skin helps maintain healthy skin balance and supports healing without scarring.
- Use SPF Daily: Sun exposure darkens scars and pigmentation, making them more noticeable and longer-lasting. Applying broad-spectrum sunscreen every day helps protect sensitive, healing skin.
- Choose Non-Comedogenic Products: Use makeup and skincare labeled “non-comedogenic” to avoid clogging pores, which can trigger new acne and worsen existing scars.
Treatment and Procedures for Acne Scar Removal
If acne scars have already made their appearance, don’t worry, there are effective skin treatments for acne marks to help fade and removal of acne scars. Dermatologists offer a range of options tailored to different scar types and skin concerns:
1. Microneedling for Acne Scars
This treatment uses a device covered in tiny needles that create controlled micro-injuries in the skin. These tiny punctures stimulate your body’s natural collagen and elastin production, helping to fill in depressed scars and improve overall skin texture. It’s great for both shallow and some deeper scars.
2. Chemical Peels for Scars
Chemical peels involve applying an acid solution that exfoliates the outer damaged skin layer. This reveals fresher, smoother skin underneath and can lighten post-acne pigmentation. Different peel strengths target various scar depths—from mild discoloration to moderate textural changes.
3. Laser Treatments
4. Dermal Fillers
For deep, sunken scars, dermatologists can inject fillers underneath to lift and smooth the skin surface instantly. This is usually a temporary solution but can be combined with other treatments for longer-lasting results.
5. Subcision & Excision
Subcision is a minor surgical procedure where a needle breaks fibrous scar bands beneath the skin, releasing tension and raising depressed scars. Excision involves cutting out deep scars entirely, followed by careful skin stitching. These are often recommended for severe or stubborn scars.
6. Topical Treatments
Products containing retinoids, niacinamide, alpha hydroxy acids (AHAs), and vitamin C help promote skin renewal, fade pigmentation, and improve texture. While topical treatments are less invasive, they work best when combined with in-clinic procedures.

How Long Will It Take to See Results?
Patience really is your best friend when it comes to treating acne scars. Most treatments work gradually as your skin needs time to repair and regenerate:
- Topicals: Expect to see improvement in pigmentation and texture after about 6-12 weeks of consistent daily use.
- Chemical Peels: Typically, 3-6 sessions spaced weeks apart are needed to reveal smoother skin and reduce discoloration.
- Microneedling: Most people notice visible improvements after 3-5 sessions, with collagen remodeling continuing for months.
- Laser Treatment: Noticeable changes often appear after 2-4 sessions, but full benefits develop over several months as new collagen forms.
Remember, regular treatment combined with expert care and a solid skincare routine will maximize your results and lead to glowing, healthier skin.
