Acne Scars: Causes, Diagnosis, Types & Treatment


Acne scarring

Acne is a common skin condition that affects millions of people. While the actual condition can be distressing, for many, it is the lingering marks and scars that cause the most concern. In this comprehensive guide, we'll dive into everything you need to know about acne scars: how they form, the various types, and most importantly, the multiple treatment options available.


Whether you're a skincare aficionado, a current acne sufferer, or simply someone who wants to understand how to manage these pesky marks, read on. We'll cover the gamut from what causes acne to how different types of scars are treated, all aimed at helping you chart a clear path to smoother, blemish-free skin.


Acne scars can be an unwelcome reminder of past or current battles with acne. These indelible marks often have deep psychological impacts, affecting one's self-esteem and confidence. But what exactly are acne scars, and how do they differ from the acne we typically focus on treating?


How Does Acne Cause Scars?

The process leading to acne scarring is a combination of inflammation, excessive oil production, and the presence of the acne-causing bacteria, Propionibacterium acnes. When the follicle wall breaks due to this combination, it can lead to infected material spilling out into the dermis. The body's response to repair the damage can result in the formation of an acne scar.


The Different Types of Acne Scars

There are several types of acne scars, the most common including:


  • Ice Pick Scars: These are deep, narrow pitted scars that extend into the dermis, appearing like the skin has been punctured.

  • Boxcar Scars: Wider depressions with more distinct edges, resembling the scars left by chickenpox.

  • Rolling Scars: Wavelike in appearance, these are shallow and wide depressions that make the skin appear uneven.

  • Hypertrophic Scars: Raised scars that are usually red or the same color as the surrounding skin. These are often less common and the result of excess collagen production in the healing process.

  • Keloid Scars: Even more pronounced than hypertrophic scars, keloids extend beyond the original wound’s boundaries and rarely regress.


Symptoms and Causes

What Causes Acne?

The causes of acne are not fully understood, but we do know that multiple factors contribute to its development. These include:


  • Excess Oil Production: The body's sebaceous glands produce an excess of an oily substance called sebum, which is more likely to get clogged in the hair follicles.

  • Hormonal Changes: Hormonal changes during puberty, menstrual cycles, pregnancy, and even stress can lead to the production of more sebum.

  • Bacterial Infection: Bacteria can exacerbate the inflammation in these clogged areas, leading to the formation of acne.


The primary cause of acne scars is the body's inflammatory response to acne lesions. Acne can reach deeper layers of the skin and damage the skin and tissue underneath. When the body tries to repair this damage, it can produce too much or too little collagen, leading to the various types of scars observed.


Management and Treatment

Will My Current Acne Breakouts Interfere with the Treatment for My Acne Scars?

It is ideal to wait until your acne is under control before starting any treatment for scars. Focused treatment on scars while acne is active can lead to poor outcomes. Once the active acne is treated and stable, scar treatments can begin.


What In-Office Treatments are Most Effective for Improving Acne Scars?

Several in-office treatments are highly effective in reducing the appearance of acne scars, including:


  • Potenza Microneedling

  • Chemical Peels

  • Dermabrasion

  • Microdermabrasion

  • Laser Resurfacing


Is Surgery Performed to Remove Acne Scars?

Surgical removal is usually not the first line of treatment for acne scars. However, some techniques, such as punch excision and subcision, can significantly improve the appearance of certain types of scars.


What’s the Treatment for Acne Scars That Aren’t on the Face?

The same treatments for facial acne scars are generally appropriate for acne scars on other parts of the body. However, certain areas may benefit from special considerations, such as skin thickness, or be excluded due to a risk of side effects.


Are Treatments for Acne Scars Different for Teenagers and Adults?

In general, the goal of treatment is similar for both teens and adults, to reduce the appearance of acne scars. The approach may differ due to the potential for acne scars to continue forming in teenagers and the differences in skin thickness and healing rates.


How Can I Reduce My Risk of Acne Scars?

To prevent acne scars, early intervention is key. If you have active acne, especially severe forms, seeking a dermatologist's treatment can help prevent scarring. Also, avoid picking or squeezing acne lesions, as this can worsen inflammation and lead to scarring. Lastly, protecting your skin from the sun can also help prevent scars from becoming more pronounced.


Home Remedies and Lifestyle Changes

Can Home Remedies Help with Acne Scars?

While some home remedies like lemon juice and aloe vera can provide minor improvements, they are not as effective as medical treatments. However, they can be a good complement to professional care.


Should I Make Any Lifestyle Changes to Improve My Acne Scars?

Adopting a healthy lifestyle can contribute to overall skin health, potentially leading to an improvement in the appearance of acne scars. Maintaining a balanced diet, protecting your skin from the sun, not smoking, and managing stress are all beneficial for skin health.


Professional Help and Diagnosis

When Should I Seek Professional Help for My Acne Scars?

If you have significant or bothersome acne scars, you should consult a dermatologist. They can help diagnose the type and severity of your scarring and recommend appropriate treatment.


Can a General Healthcare Practitioner Diagnose and Treat My Acne Scars?

While a general healthcare practitioner may provide some information, the best treatment options will be found with a dermatologist, who is specially trained to diagnose and treat skin conditions.


Acne scars are more than just skin deep. They can impact our mental health and the way we interact with the world. However, the good news is that with advancements in dermatology, there are numerous treatment options available, ranging from at-home care to in-office procedures.


The journey to clear, smooth skin is a personal one, and what works for one person may not work for another. The key is to be patient and persistent and to work closely with a skincare professional to find the best approach for your unique skin and situation. Remember, every step you take towards understanding and treating your acne scars is a step towards greater self-confidence and well-being.
