Causes of Acne / Pimples (Acne scars)

The severity of acne / pimple scarring is multifactorial. It is caused by a combination of factors such as skin type, genetics, hygiene, and stress. There are many commercial treatments and do-it-yourself articles claiming to help solve acne problems and subsequent scarring but none of these seem to actually work. The most common cause of scarring is still “self-pimple-popping” which causes further infection and inflammation making the problem worse.

Inflamed pimples with or without pus (pustules) are more likely to become acne scars, while comedones or black heads on the other hand, tend to leave less scarring. Acne scars are divided into different types: hypertrophic or raised, keloids, craters, and hyperpigmented or red/dark brown scars. In particular, hypertrophic and keloid scars are often quite difficult to treat and remove and many people suffer from this problem.

For flat or depressed acne scars, the treatment process works through new skin regeneration from the dermis collagen layer. Hyperpigmentation and skin redness problems, can be effectively addressed by therapy.

Non-invasive or non-surgical treatments include Photofacial and Salicylic Acid Peeling (BHA Peeling). Other acne scar treatment regimens we offer include Trichloroacetic Acid (TCA) Peeling and CO2 Laser Ablation. We also offer Fractional Skin Resurfacing semi-ablation therapy. For Hypertrophic and Keloid scars, we also recommend and offer localized injection or laser treatments.

Different Types of Acne Scars

Crater (Indented) Scars
After resolution of cystic acne (highly inflamed pimples often with pustules/pus), crater-like indentations / scars are formed. Since the scarring involves the deep dermis layer of the skin, natural healing is often difficult. We do treatments to stimulate the collagen remodeling of the skin to decrease crater scars and enhance skin reformation.

Pigmented Scars
Acne often leaves dark, pigmented scars or skin discolorations. We do treatments using Vitamin C to promote faster healing and skin peeling to remove dark scar-tissue formations.

Keloid Scars
Keloids are firm, rubbery lesions or shiny, fibrous,round scars that has colors that can vary from pink or red to dark brown and often extend outside wound borders. It is caused by an overproduction of collagen and overgrowth of granulation tissue at the site of wound or acne healing. We provide treatments that reduce the raised collagen tissue and remove the skin discoloration.

Hypertrophic (Raised) Scars
During the course of acne or wound healing, skin cells and connective tissue cells (fibroblasts) begin multiplying to repair the damage. Sometimes, overproduction of these components lead to raised or elevated scars that stay within the borders of the wound. Similar to Keloid scars, we provide treatments to reduce and improve hypertrophic scars.

Acne Scar Treatment

Acne scar treatments (or combinations of treatments) reduce skin indentations and depressions by stimulating collagen production which fills up the scars.
Non-Ablative         Semi-Ablative         Ablative

No medication is necessary and there is zero-to-minimum down-time. May require multiple treatments for the optimal results. Examples include

Chemical Peeling



Some down time expected but faster recovery compared to Ablative procedures. Examples include

● Fractional Resurfacing

Fractional resurfacing is the latest new system which delivers more than 1000 microscopic laser beams (60µm in diameter, 0.048~1.5mm in depth) to the dermis and creates the Microthermal Treatment Zone (MTZ)
The coagulated MTZ tissue then begins to remodel collagen which generates new healthy tissue during the natural healing process.
This system has the benefit of both ablative and non-ablative skin resurfacing treatment. Unlike other skin resurfacing systems, uniformed micro beams and precise depth control enable deep tissue penetration with remarkable results.

After 2nd treatment


Medication may be necessary for several days and some down-time is expected. Rapid improvement is common and few treatments are necessary. Examples include



Acne Scar FAQ

Q.I have acne scars all over my face. What are the available treatment options?
A.There are several treatment options available for acne scars. Our Doctor will advise you on the most effective treatment or combination of treatments based on your current scar condition and your preference to post-treatment reactions.

Q.Is it safe to ‘pop’ my acne?
A.Popping pimples can cause complication such as infections and scarring. If a pimple requires popping, an experienced physician should perform the procedure.

Q.I have already tried chemical peeling and laser treatment for my acne scars but I am unhappy with the results. Are more aggressive treatments available?
A.Yes. We have recently introduced one of the latest acne scar treatments called Fractional Resurfacing. Fractional Resurfacing uses micro-laser energy to stimulate new skin growth and induce collagen production without ablating the skin surface completely. The effect is noticeable after the first treatment.

Q.I prefer a treatment with no down-time due to obvious reactions such as redness and swelling. Is such a treatment available?
A.Yes. Photofacial and Chemical Peeling effectively induce collagen production without damaging the skin surface. Therefore, there is no post-treatment redness or inflammation, and you can apply make-up immediately after the treatment. It is also possible with Fractional Resurfacing to limit post-treatment reactions by carefully controlling the laser intensity.

Q.What reactions can I expect after receiving Factional Resurfacing treatment?
A.You may experience redness and swelling for several hours to several days post-treatment depending on the laser intensity used. However, laser intensity can be adjusted to suit your reaction preference. You may also experience dryness and roughness of micro scabs for up to ten days following treatment. During this time, it is important to moisturize and protect the treated area from UV exposure. Micro scabs will shed off naturally after some time. Therefore, you should not peel or scratch them.

Q.What reactions can I expect after FGF or TCA treatments?
A. After FGF treatment, only the prescribed topical medication and dressing tape are allowed on the treated area until the skin is completely healed a process which usually takes from seven to ten days. Make-up should be avoided on the treated area during the healing phase. The treated area usually becomes slightly red when the skin is healed. After TCA treatment, the treated area becomes frosty-white and eventually turns into a scab that is later shed off. It is fine to apply make-up over the frosty scab immediately after the treatment. For a few months following treatment, the treated area remains slightly pink but does not need medication.

Q.How many treatments will I need?
A. The number of treatments required for effective results varies from patient to patient and is determined by skin condition, treatment type, treatment intensity, and post-treatment reactions. For Fractional Resurfacing, a single treatment can be effective. But for further improvement, we recommended additional treatments usually two or three. For Photofacial and Chemical Peeling, several treatments over a two-to-three week period will be most effective. For FGF and TCA, a single treatment can sometimes remove an acne scar. However, several treatments are sometimes required.
