Acne Scars – Causes, Treatment & Recommended Removal Method

What Causes Pimple Scars?

Pimple scars, acne scars or acne marks are usually caused by inflamed lesions and enlarged pores that leave a break in the follicle wall. As the body attempts to heal itself by forming new collagen fibers to replace the lost tissue that has been destroyed, it doesn’t usually end up as smooth and flawless as before. As the wound heals, the body can sometimes produce either too much or too little collagen, creating raised tissue or an indentation on the skin’s surface. Many patients are concerned if these acne scars can be removed.

A patient typically went through many treatments and home remedies for acne scar removal before seeing a doctor. There are several treatments for those suffering from pimple scars. Some treatments are more effective for specific types of acne scars. Suitable treatment options may vary slightly depending on the type of scarring that acne has caused. There are three types of acne scars:

acne scar before and after treatment and removal

1. Atrophic scars 

These are small indentations in the skin. They occur when the skin does not produce sufficient fibroblasts during the healing process. As fibroblasts are cells that play a crucial role in wound healing and the synthesis of collagen. Atrophic scars are usually the results after acne, chicken pox, and indented scars. The indentation can form into one of three types of scarring:

Icepick, rolling, boxed acne scars and Keloid Scars

Treating Acne Scars

Scarring after acne occurs frequently. It is an unwanted reminder of a painful and bothersome condition. However, acne scars do not have to be permanent, as recent advances in laser and ablative radiofrequency technology have allowed us to offer effective treatments in minimizing unsightly scar damage to the skin after acne.

There are several types of treatment that can help reduce acne scars or acne marks and improve the overall skin quality

  • Medical Laser Treatment

    Laser treatment helps to lighten acne scars as it smooths away the top layer of the skin. It can also reduce the pores and help with resurfacing the skin. It is not suitable for patients who are still suffering from breakouts as well as darker skin tones.
  • Non-Ablative Lasers

    Treatments help with the stimulation of new collagen production. It helps to reduce pores as well as lighten and smoothen acne scarring.
  • Medical Peels

    Medical / Chemical Peels use strong acid to remove the top layer of the skin to reduce deeper scars. A good complement treatment for pimple scars
  • Dermal Filler

    Fillers can help to plump the skin by using collagen to smoothen out depressed scars and even out skin tone.
  • Puro

    Puro uses 160 micro pins to safely deliver heat via NanoFractional RF™ through the skin’s surface. The pins create tiny micro-dermal wounds, which the body then works to heal naturally. This process is what repairs signs of skin damage seen on the surface of the skin. And because the wounds are so small, the treatment is much more comfortable than lasers, and results in smoother, healthier skin with minimal downtime.
  • Intensif Microneedling RF

    This therapy is good for depressed scars that lie more than 1.5mm deep below the skin, micro needling helps. It is a procedure that uses a small, handheld, needle-studded roller containing multiple fine needles to puncture the top layer of your skin. How this works is that it encourages peeling it triggers the production of collagen and elastin as the skin tries to heal, leaving skin with a smoother appearance. Results can be seen within six to 12 weeks after treatment. This is a popular treatment because there’s less risk of side effects, although slight bruising can occur during the process. However, it is not suitable for those currently suffering from an acne breakout, rosacea or eczema.


Acne Scar Removal in Singapore – Why We Don’t Use CO2 Lasers

In the past, treatment for acne scars or acne marks were CO2 fractional resurfacing lasers. CO2 fractional lasers treat scars by gradually removing a few microns from the upper layer of the skin. This resurfacing treatment is more suitable for Caucasian skin as compared to Asian skin. If used on Asian skin, complications of hyperpigmentation and burns often occur, resulting in multiple treatments. Results when using this treatment for deeper scars is unsatisfactory, because more complications arise, as well as longer downtime for patients.

So here are some of the results why Dr Kenneth Thean and Dr Chiam Chiak Teng recommend a different approach when it comes to pimple scar removal in Singapore. Instead of using the CO2 laser, I prefer to use the safer Erbrium Yag lasers, and ablative radiofrequency technology; these are more suitable for use on Asian skin.

We can now quite easily target the scar to almost the full thickness of the skin. The 500 micron ablative depth, can treat the deep scar tissue that pulls the skin surface down. Dermal lasers are also used to stimulate the growth of the skin's collagen. This triple-action of deep fractional skin resurfacing, which releases the tethering scar fibers and rebuilds the skin’s collagen matrix, means the skin is restored to its natural position, resulting in much smoother skin. Other treatments such as Chemical Peels can also reduce scarring appearance.

Significant improvement is achieved after just one treatment. With the reduction in the risk of complications, multiple treatment sessions can be carried out safely. We can thus achieve a considerably smoother skin surface safely and effectively.
