Our skin being the largest organ in our body consists of three main layers – the epidermis, the dermis and the hypodermis. They are filled with sebaceous glands to help to provide a moisturized environment for the cells, but excessive secretion of sebum from the glands may clog the skin and give us acne.


The acne pore gets inflamed and a breakdown occurs in the wall of the pore. Sometimes the contents of the acne spill over into the surrounding tissue, causes more damage and result in deeper scars. The skin’s response is to repair the damaged tissue by forming new collagen fibers – this result in acne scar formation.



Acne Scars exists in 2 forms:


  1. Depressed Acne Scar (indented): when there is a loss of tissue, resulting in an indentation in the surface of the skin


  1. Hypertrophic Acne Scar (raised): skin creates collagen to help to heal the wound but over-stimulation of collagen will result in a raised scar form.


Types of Acne Scars:

Deep diving into the different kinds of Acne Scars, Depressed Acne Scars itself have different types.

The illustration below explains the different types of acne scars.


Rolling Scars:  Wide base, rounded edges

Ice Pick Scars: Small entry point with sharp steep edges; like a “V”

Boxcar Scars: Wider base, sharply demarcated edges; like a box; They can be superficial or deep.

Pigmented scars: Dark spots /discolouration left behind by acne.

Hypertrophic scars and Keloids: Raised, thick scars


How to remove and treat Acne Scars?

It is a struggle and always everyone’s dream to remove their acne scars. So what is the best way? Well, it is easier said and imagined but in actual fact, Acne Scars are permanent due to the damage in the skin tissues.


It can’t heal and disappear by itself, but acne scar removal treatments can help to reduce the appearance over the number of sessions and help to improve our appearance.  For depressed scars, we are able to improve it by up to 80%!

Some may think that Acne Scars will fade away over time. Yes, the Acne Pigment Scars will fade over time but not so for the Depressed Acne Scars.


With that in mind, it is wise to treat Acne Scars as early as you can for best results. New and freshly formed Acne Scars generally react best to treatment with better results obtained. So do not delay treatment for too long if possible.

Treatments for Acne Scars

As there is no one solution to treat Acne Scars, it is wise to understand the stage or severity of your scars as it will help you to determine which type of treatment will be more effective to get rid of them.


a) Mild Stage of Acne Scars
Acne pigment marks and shallow scars which only cover a small portion of your face. Lasers such as the Spectra XT Laser and Advanced eCO2 Fractional Laser can help to resurface the skin, and lighten the acne spots.

b) Moderate Stage of Acne Scars

Deeper depressed scars (Ice Pick and moderate Rolling/ Box scars) that cover a relatively bigger area of your skin. Combination of Advanced eCO2 Fractional Laser with Subscision can help to resurface the skin and to stimulate new production of tissue formation in your skin.

The TCA CROSS technique which comprises of very high concentration TCA ACID is also used to treat the Ice Pick scars.


c) Severe Stage of Acne Scars

Very deep scars (can be a combination of Ice Pick scars, Rolling Scars, and Boxed Scars) that are found in abundance in your skin. Combination of TCA Cross Chemical Peel, Advanced eCO2 Fractional Laser, Microneedle Radiofrequency and Subscision will help the skin in all angles to resurface its layers, stimulate new production of collagen and renew the skin tissues.


How long does it take to remove Acne Scars?

There is no definite answer as to how long of a duration of time is needed to remove the Acne Scars. There are many factors such as current skin condition, intensity and type of acne scars, skin response and lifestyle habits.


But what is apparent is that Acne Scars cannot be reduced fully just with one treatment. For example, if a person who has mild to moderate stage of Acne Scars, about 3-7 sessions are needed with visible improvement after each session. Each session can be done every 4-6 weeks. That works out to be about 20 – 28 weeks ( 5 – 7 months).


However, for a person with severe stage of Acne Scars, an average of 6-10 sessions are needed, with a total of 32 – 40 weeks (8 – 10 months) for best results.

The Acne Scar Removal Treatment Plan may require a length of time, however, it is vital to follow through with the plan for best results.
