Why Do Some People Have Acne Scars While Others Don’t?

Acne breakouts are frustrating and nobody wants to deal with them. Things get even worse when they leave scars on our face as well as other body parts where they might appear. But does that happen to everyone? Probably not! There are different reasons why some people have acne scars while others don’t, but if one does have them, they can consider going for Acne scar removal treatment in Singapore and get the most appropriate type of acne scar treatment for them.

Factors Often Responsible For Acne Scars

Before we look into different acne scar treatment options available, let’s explore what might be the reason behind these acne scars in the first place. Sometimes, one can get lasting scars from acne even when they decide to keep their hands off the face all the time. Common causes for acne include:

causes of acne scar


Scarring often happens due to genetic reasons in some people. Those who have a family history of getting acne scars are often more prone to getting them. So, they should take extra care of their skin or seek early medical treatment if acne concerns arise.

Sun Exposure

We all understand the importance of vitamin D we absorb from sunlight, but one should make sure that they do not get way too much of it. While scarring may not directly result from intense sun exposure, it can definitely be a contributing factor and can make those marks darker. If there is a need to be under the sun for long hours, be sure to apply sun block to prevent scars from worsening.


Puberty brings a lot of changes in the body and can often result in acne breakouts, leading to acne scars. Teenagers often experience more acne due to those hormonal changes happening in their bodies. And, with more acne comes a greater risk of developing acne scars.

Acne Severity

Yes, scarring has a direct relation to how severe an acne breakout one might experience. Scarring is more common in cases of more inflamed, deeply rooted, and widespread acne.

Acne Frequency

Acne scars are also more common in individuals who experience acne breakouts too frequently.

Androgen Levels

Acne scars can develop in both men and women, however, they are often more prominent in men. One reason for that is men often develop relatively severe and more persistent acne due to the presence of androgen in their body.


The formation of stubborn acne scars is also related to how sooner one might get their acne treated. The longer one might wait for getting their acne treated, the higher the risk of getting acne scars.

Do Some People Have A Higher Risk Of Getting Acne Scars?

As mentioned above, some people get acne scars due to genetics. So, if issues like keloid scarring and hyperpigmentation run in one’s family, they are definitely more prone to getting scars from acne. Particularly, keloid scarring is more common among some ethnic populations. It is, generally, common in Asian skin and dark skin and also the fair-skinned redheads.

So, if one’s siblings or parents have had scars due to acne or they struggled with post-inflammatory hyperpigmentation, they should definitely see a dermatologist before they develop lasting acne scars. It is important for them to get proper guidance on the treatment of acne and also types of acne scar removal treatments available in Singapore.

Why Scarring Doesn’t Happen From All Acne Breakouts?

how acne scars form

Acne doesn’t always cause scarring, and it may go away leaving one’s skin as natural as it was before. So, what’s the reason behind that?

Well, acne leads to scarring when there is significant inflammation in the skin. Inflamed skin initiates a natural healing response as new collagen fibers are formed. When the skin goes into an overdrive, however, it tends to cause a raised scar due to excess accumulation of collagen tissue.

As more blood cells to gather in the affected area, enzyme production starts, and this includes some particular wound-healing enzymes as well that help produce collagen.

If the collagen works like it normally does, acne may not leave any scars or blemishes behind. However, these collagen-inhibiting enzymes – often known as MMPI enzymes – can sometimes mess with the production of collagen, sending the skin into an overdrive of collagen production and result in raised scarring.

In other cases, there may also be tissue loss along the healing process. When the acne is drained completely, the space between the top and bottom layer is emptied. This causes the top layer of the skin to rest on top of the dermis. As collagen fiber forms, it binds both skin layers, pinning the top layer down to the dermis, which results in a depressed scar.

Acne scars are more common in cases of cystic acne. The reason is that this type of acne is often infected. On the contrary, comedonal acne that mostly consists of blackheads or whiteheads is way less likely to leave scars on the skin. If one picks at their skin to get rid of these blackheads or whiteheads, however, it increases inflammation and they have a greater chance of getting acne scars.

Types Of Acne Scars

types of acne scar

Acne scars can be classified into 2 categories, mainly:

Atrophic Scars (Depressed)

  • Boxcar scars
  • Rolling scars
  • Ice pick scars

Hypertrophic scars (Raised)

  • Raised lumps
  • Keloid scars

What Options Are Available For Acne Scar Treatment?

There are different acne scar treatment options available. One should consult with their local physician to decide which of these treatments would work best for them. Generally, acne scar can be improved using one of the following methods:

For Depressed Acne Scars

  1. TCA Peels

In cases of moderate or mild acne scarring, a skincare professional would recommend glycolic or trichloroacetic (TCA) peels. TCA can be applied onto scars to help form extra collagen that may raise the scar.

TCA peels with 25% to 35% concentration often work well to treat moderate acne scars. They can also effectively remove older scars that are often more challenging to get rid of.

Peels are capable of improving scars on almost all skin tones. However, people with a dark skin tone should be cautious when getting TCA peels. It is advised that a test patch should first be treated to ensure that they don’t experience any post-inflammatory hyperpigmentation.

  1. Lasers

Laser resurfacing is a way to trigger the body’s natural repair process so that it can synthesize new collagen and resurface those deepened and scarred skin areas. During the laser treatment, light beams are reflected on the treatment site to heat the dermis layer of the skin. As a result, a remodeling process is triggered to help plump those depressed areas as well as the area surrounding the treatment site. This makes the scars less obvious.

  1. Fillers

Dermal fillers usually fill or plump up those depressed or atrophic acne scars. The fillers needles can be used to break the collagen bands that is pulling the skin down, after which fillers are injected directly into the treatment site for creating a smooth surface while restoring the skin’s natural plumpness and volume. Fillers are often used when scars cause a deep hole in the skin. One can consider fillers, especially, in cases where laser treatment doesn’t work the way as expected to get rid of the issue.

  1. Subcision

Subcision is an acne scar treatment that releases the scars that have tethered down within the deeper skin layers. This surgical procedure is often known as subcutaneous incision-less surgery. It is effective when the scars aren’t present in the subcutaneous tissue and are rather located in the dermis skin layer. To reach those deep scars, a special type of needle is introduced into the skin to break down the anchoring tissue that keeps the skin anchored to those deepest layers. When the healing starts, this treatment also stimulates collagen production and natural skin repair.

  1. Dermal Grafting

This treatment for acne scar removal in Singapore uses skin grafting for the treatment of acne scars. It levels up any depressed areas on the skin using the natural skin tissues which is commonly taken from the back of the ear. When the scar depressions are leveled, the overall skin texture of the patient is also improved without any artificial fillers or implants. This procedure is often recommended for patients with rolling scars or boxcar scars formed due to an acne breakout and can also be effective for chickenpox scars.

For Raised Scars

Steroid injections and laser skin resurfacing therapy are the two options to treat raised scars effectively.

  1. Steroid injection

For the steroid injection treatment, the doctor injects steroids into the scars directly to soften them up. It, eventually, reduces scar height. Several steroid injections, given a few weeks apart, may be needed for this treatment to work.

  1. Laser Skin Resurfacing

Laser skin resurfacing therapy is also a good treatment option for raised scars. However, it is a more effective treatment option for scars that have been newly formed as compared to the older ones. The laser burns and flattens the elevated scars. It also targets any pink and red pigments in the raised scars and lightens them.


Acne scars are formed due to a variety of reasons, genetics being one of them. As there are different factors responsible for scarring after acne breakouts, some people are often more prone to acne scars than others. Different acne scar treatment options are available to treat different types of scars. One must consult with their physician in Singapore for acne scar removal so that they can come up with the most appropriate treatment option for them.
