Acne Scar Treatment & Removal in Singapore

The Fractional Erbium Laser (欧洲之星) is a resurfacing laser that delivers energy in a fractional pattern — treating thousands of microscopic columns within the skin while leaving surrounding tissue intact. This fractional approach triggers robust collagen remodelling and new skin growth in the treated columns, while the untreated tissue around each column accelerates healing. The result is a meaningful improvement in atrophic scar depth and skin texture with a significantly shorter recovery compared to full-beam ablative treatments.

The Erbium laser causes minimal thermal damage to surrounding tissue, making it particularly suitable for patients with moderate skin tone (Fitzpatrick III–IV) who require a more conservative approach to avoid post-inflammatory hyperpigmentation. Downtime is typically 3 to 5 days of redness and mild peeling.

The Fractional CO2 Laser (点阵激光) is a more intensive fractional resurfacing treatment that delivers CO2 laser energy to create controlled micro-ablation zones within the skin, stimulating a stronger collagen remodelling response than the Erbium laser. It is most effective for deeper atrophic scars, including boxcar and rolling scars, where more significant tissue remodelling is required.

CO2 fractional laser typically delivers greater improvement per session than the Erbium, but with more downtime, usually 5 to 7 days of redness, swelling, and peeling. It requires careful patient selection based on skin tone, as the risk of post-inflammatory hyperpigmentation increases in darker skin types. Our doctors select appropriate laser settings and pre-treatment protocols to minimise this risk.

The Full Beam Resurfacing Laser delivers ablative laser energy to renew damaged skin areas. It is helpful for patients with widespread textural changes, significant atrophic scarring across large areas, or where previous fractional treatments have reached their improvement ceiling.

Results are typically more dramatic, with a recovery period of around 7 to 10 days involving redness and peeling as the skin renews itself.

The Pico HEXA MLA Laser delivers focused pico laser energy into tiny targeted areas beneath the skin, triggering collagen remodelling and lifting and filling atrophic depressions. 

Because the skin surface is not ablated, downtime is minimal, typically mild redness for 24 to 48 hours, making this a well-suited option for patients who cannot take time off work for a longer recovery. It is particularly effective for shallow to moderate boxcar and rolling scars and works well in combination with subcision for rolling scars.

RF Gold Microneedling (黄金微针) delivers radiofrequency energy through gold-tipped microneedles directly into the dermis at precisely controlled depths. For acne scar treatment, this dual mechanism — physical micro-injury from the needles plus heat from the RF energy — creates a targeted remodelling stimulus at the depth of the scar tissue itself.

It is particularly effective for improving overall skin texture, reducing pore size, and providing a progressive lifting effect on shallow to moderate atrophic scars. Because the skin surface is largely spared from damage, the risk of post-inflammatory hyperpigmentation is lower than with ablative lasers, making it a strong option for patients with darker skin tones common in Singapore. Downtime is 1 to 2 days of redness and minor swelling.

Sofwave™ (索夫波) uses Synchronised Ultrasound Parallel Beam (SUPERB™) technology to deliver precise ultrasound energy to the mid-dermis at a depth of 1.5mm, the primary layer where collagen remodelling needs to occur for scar improvement. 

For acne scar patients, Sofwave is particularly useful for supporting collagen production and improving overall skin quality and firmness in scarred areas, complementing treatments such as fractional lasers or subcision. There is no downtime, and it is suitable for all skin types, including darker skin tones.

Subcision is a minimally invasive procedure in which a fine needle or cannula is inserted beneath a rolling scar to release the fibrous tissue bands pulling the skin downward. Once these bands are released, the skin is able to lift more smoothly, allowing subsequent collagen-stimulating treatments such as lasers or RF microneedling to work more effectively.

For rolling scars, subcision is frequently the single most important first-line treatment. Without it, resurfacing treatments cannot fully correct the tethering effect, causing the wave-like depression. Subcision is typically performed in a series of sessions and is combined with other scar treatments for optimal results. Post-procedure bruising and mild swelling for 3 to 7 days are normal and expected.

TCA Cross (Chemical Reconstruction of Skin Scars) is a targeted technique in which a high concentration of trichloroacetic acid (TCA) is applied to the base of individual ice pick or deep boxcar scars using a fine-tipped applicator. The focal chemical injury stimulates collagen production specifically within the scar channel, causing it to gradually fill from the base up over a series of treatments.

TCA Cross is one of the most effective available treatments for ice pick scars, specifically, a scar type that does not respond well to resurfacing lasers or RF energy because the scar extends too deeply. It is typically performed in a series of 3 to 6 sessions at 4 to 6 week intervals, with progressive improvement in scar depth visible after each session. Post-treatment, treated areas will scab and heal over 5 to 7 days.

The HTIC Collagen Skinbooster is a high-concentration injectable that delivers type I collagen directly into the dermis. For acne scar patients, it serves a dual role: improving the overall skin density and quality of the scarred area, which makes the skin more responsive to resurfacing treatments and providing direct collagen stimulation that supports scar remodelling between and after more intensive procedures.

It is particularly useful as a supportive treatment for patients undergoing fractional laser or subcision protocols, helping to optimise the skin’s healing environment and extend the results of those treatments.

Korean PN Scar (婴儿针) is a scar-specific polynucleotide formulation designed to stimulate cellular repair and accelerate tissue regeneration in scarred skin. Polynucleotides deliver biological signals that activate the skin’s own repair mechanisms at a cellular level, promoting fibroblast activity, collagen synthesis, and healthy tissue remodelling.

For acne scar treatment, Korean PN Scar is typically used as a combined or adjunct treatment alongside resurfacing lasers or subcision, supporting and accelerating the healing process between sessions while independently contributing to scar improvement.

PN Newest (神颜针) is an advanced polynucleotide formulation combining deep skin renewal with targeted regenerative activity. In the context of acne scar treatment, it improves post-treatment skin quality, supports ongoing collagen remodelling, and helps maintain results between sessions of more intensive procedures. It is particularly valuable for patients whose scar treatment protocol spans several months, providing ongoing cellular support throughout the process.

PN Restore addresses compromised skin at a regenerative level, making it relevant for acne scar patients whose skin has been stressed by years of inflammation, previous aggressive treatments, or significant scarring. Restoring the biological environment of the skin from within, it creates a more receptive foundation for the remodelling effects of laser and energy treatments.
