What Are Acne Scars? Causes and Effective Treatment Options
Acne scars are a common skin condition that appears after inflammatory skin damage such as acne, chickenpox, or other skin injuries.
These scars usually form as depressed areas on the skin’s surface, making the skin look uneven and less smooth.
For many people, acne scars not only affect appearance but also reduce confidence in everyday communication.
However, by understanding what acne scars are, what causes them, and which treatment methods are effective, it is absolutely possible to improve the skin’s condition.
The article below will help you better understand how acne scars form and the scientific treatment solutions available today.

What Are Acne Scars and How Do They Form?
Acne scars are a type of depressed scar that forms when the collagen and elastin structure in the skin is severely damaged.
When the skin experiences inflammation or deep injury, the body activates its self-healing mechanism. However, if the repair process is incomplete, the damaged area will be left with a deficiency of connective tissue.
As a result, the skin surface sinks inward and forms acne scars.
Acne scars commonly appear on the cheeks, forehead, and chin, which are areas more prone to inflammatory acne and prolonged skin damage.
These scars may remain for a long time if they are not treated properly.
That is why understanding what acne scars are is important in choosing the right skincare and treatment approach.
Common Types of Acne Scars
Not all acne scars are the same.
In dermatology, acne scars are often classified into different types based on their shape and depth.
Identifying the correct type of scar helps make treatment more effective.
Ice Pick Scars
These are small, narrow, and deep scars.
The opening of the scar is usually very small, but it extends deep into the dermis.
Ice pick scars often appear after severe inflammatory acne and are very difficult to treat without advanced technologies.
Boxcar Scars
Boxcar scars are round or square-shaped depressions with clearly defined edges.
They can range from moderate to deep in depth.
This type of scar commonly appears on the cheeks and can often be improved effectively with modern skin resurfacing treatments.
Rolling Scars
Rolling scars create shallow, wave-like depressions on the skin’s surface.
They are often caused by fibrous bands beneath the skin pulling the surface downward.
This type of scar makes the skin look uneven and less smooth.
Common Causes of Acne Scars
To understand what acne scars are and how to treat them effectively, it is important to know the main causes.
Acne scars usually develop after severe skin damage or improper skincare habits.
Severe inflammatory acne
This is the most common cause of acne scars.
When inflammation spreads deeply into the dermis, the skin tissues may be destroyed.
If the healing process is incomplete, depressed scars can form.
Improper pimple extraction
Many people have a habit of squeezing pimples at home.
This can easily damage the skin structure and spread bacteria.
As a result, the risk of acne scar formation increases significantly.
Improper skincare
Using unsuitable skincare products or not cleansing the skin properly can make acne worse.
When acne lasts longer, the risk of developing acne scars also increases.
Genetic factors
Some people are naturally more prone to scarring than others.
If there is a family history of acne scarring, the likelihood of developing scars after skin injury may also be higher.
How Acne Scars Affect the Skin
Many people think acne scars are only a cosmetic concern.
In reality, they also affect several other aspects of the skin.
They make the skin surface less smooth
Acne scars create uneven depressions on the skin.
This makes the skin look rough and lacking in vitality.
They affect skin elasticity
When collagen structure is damaged, the skin’s elasticity is also reduced.
The skin may become thinner and weaker.
They reduce confidence
For many people, acne scars can cause insecurity when meeting or talking with others.
This may affect mental well-being and quality of life.
Common Acne Scar Treatment Methods Today
There are currently many different methods used to improve acne scars.
Depending on the scar type and the level of skin damage, doctors may recommend the most suitable treatment.
Microneedling for skin regeneration
Microneedling is a method that uses very fine needles to create micro-injuries on the skin’s surface.
This process stimulates the body to produce more collagen and elastin.
As a result, the skin surface may gradually become smoother over time.
Fractional CO2 Laser
This is one of the modern technologies commonly used to treat acne scars.
Fractional CO2 laser works by creating microscopic thermal zones in the skin.
These controlled micro-injuries stimulate collagen regeneration and help improve the skin structure.
This technology is often applied for moderate to severe acne scars.
Subcision
Subcision is a method that uses a specialized needle to cut the fibrous bands that pull the skin downward.
Once these bands are released, the skin surface can become flatter.
This method is often combined with other treatment technologies to improve effectiveness.
Modern Technologies for Acne Scar Treatment
After understanding what acne scars are and how they form, many people ask whether acne scars can be completely improved.
In reality, acne scar treatment has advanced significantly thanks to the development of modern dermatological technology.
These methods not only act on the skin surface but also stimulate skin regeneration from within.
The main goal of acne scar treatment is to stimulate the production of collagen and elastin, helping the depressed areas gradually fill in.
Fractional CO2 Laser in acne scar treatment
One of the most prominent technologies in acne scar treatment today is Fractional CO2 laser.
This method uses microscopic laser beams to create very small controlled injuries in the skin.
These micro-injuries activate the body’s natural healing process.
This process boosts collagen production and rebuilds the skin layers.
According to many dermatological studies, Fractional CO2 laser can significantly improve the skin’s surface and reduce the depth of acne scars after multiple treatment sessions.
One advantage of this technology is that the laser energy is precisely controlled, which helps minimize damage to the surrounding skin.
Combination with biological skin regeneration
In some modern treatment protocols, Fractional CO2 laser is often combined with biological skin regeneration treatments.
These may include therapies that stimulate tissue repair and improve the skin’s ability to recover.
When combined appropriately, the treatment process may improve skin texture, support scar filling, and make the skin smoother.
Combining multiple methods for better results
Acne scar treatment often does not rely on just one method.
Dermatologists commonly create treatment plans that combine multiple techniques, such as:
-
Subcision
-
Laser resurfacing
-
Microneedling to stimulate collagen
-
Chemical peels
This combination approach helps target multiple mechanisms of scar formation and can improve treatment effectiveness.
What Does the Acne Scar Treatment Process Usually Look Like?
Many people who want to know how to treat acne scars effectively also wonder what the treatment process involves.
In reality, acne scar treatment at dermatology clinics is usually carried out in several steps to ensure safety and effectiveness.
Skin examination and evaluation
The first step is always to assess the acne scars.
The doctor will determine the scar type, depth, and degree of skin damage.
This accurate evaluation helps select the most suitable treatment method.
Creating a personalized treatment plan
Each person has a different scar condition.
Therefore, the treatment plan should also be personalized.
The doctor may recommend combining several methods for better results.
Performing the treatment
After the skin is cleansed and prepared, treatments such as laser resurfacing or subcision are performed.
The process is usually relatively quick and controlled using specialized equipment.
Post-treatment care and recovery
After treatment, the skin needs time to recover and regenerate.
Doctors usually provide guidance on home skincare to support healing.
Proper aftercare plays a very important role in improving treatment results.
How Much Does Acne Scar Treatment Cost?
One of the most common questions when learning what acne scars are and how to treat them effectively is the cost.
In reality, the cost of acne scar treatment can vary depending on many different factors.
In general, each treatment session may cost from a few million to more than ten million VND.
The total cost may vary depending on how many sessions are needed to achieve the desired results.
Factors That Affect Acne Scar Treatment Costs
Several factors can influence the cost of treatment.
Scar type and severity
Shallow scars are generally easier to treat than deep scars.
Older or more complex scars usually require more treatment sessions.
Treatment technology
Modern technologies such as Fractional CO2 laser often cost more than traditional methods.
However, they also tend to provide better improvement.
Number of treatment sessions
Acne scar treatment usually requires multiple sessions for visible results.
The number of sessions varies depending on each person’s skin condition.
