The appearance of acne scarring can be unpredictable and varies from person to person. Not only will the scars remind you of what you had to deal with, but they may also make you dissatisfied with your skin and affect your confidence. "Acne scar removal Singapore", "acne scar treatment Singapore" are some of the most highly searched terms, as patients seek successful acne scar remedies.
Scarring results from abnormal healing after damage to the second layer of the skin, the dermis. Patients with atrophic scarring have an altered inflammatory cell profile and tend to experience a prolonged inflammatory response that causes collagen destruction. Raised scars as in hypertrophic or keloid scars result from an over-exuberant healing response and excessive collagen deposition. The type of acne scar treatments depends on a variety of factors such as the patient's skin type, skin cells, types of acne, need for collagen production, and whether he or she has deep acne scars.
Dr Wan uses a combination approach of these various evidence-based options to properly tailor the best possible acne scar removal treatments for you and your unique skin condition.
Fractional laser resurfacing scar removal treatment involves the deposition of a pixelated pattern of microscopic laser wounds surrounded by healthy tissue resulting in both greater efficacy and shorter downtime compared to non-fractionated treatments. It can be further subdivided into ablative and non-ablative. Ablative fractional lasers have longer wavelengths (e.g. CO2 10600nm) and lead to full-thickness destruction of skin, whereas non-ablative fractional lasers have shorter wavelengths (e.g. Erbium Glass 1550nm) and leave an intact skin surface. CO2 has greater efficacy compared with Erbium Glass but longer recovery time and a higher risk of complications.
Fractional Co2 Lasers have a good body of research evidence demonstrating safety and efficacy for deep acne scar removal in Singapore. These laser treatments are the gold standard treatment for scarring against which other treatments are compared.
Discovery Pico Plus is a second-generation triple wavelength picosecond laser that generates the highest peak power in the world. A special microlens array further focusses the energy into numerous micro-beams 2mm under the skin. The highly concentrated energy produces laser-induced optical breakdown (LIOB) stimulating scar remodeling.
One of the biggest advantages of Fractional Picosecond Laser treatments is that it stimulates collagen production with almost no downtime at all. This is due to the nature of the treatment and instrument that keeps damage to the skin layers to the very minimum. This also allows a shorter recovery period for you!
Fractional Radiofrequency creates a pyramidal thermal injury zone (a relatively large coagulation zone deep in the skin with minimal surface damage) as opposed to the columnar shape of ablative lasers. Hence Fractional Radiofrequency has a favourable side-effect profile (such as downtime, post-inflammatory hyperpigmentation) in comparison to fractional lasers.
Scar remodelling requires heat delivery to the deep part of the skin. However, in most machine-based treatments for scarring such as lasers, much of the energy is dissipated at the skin surface and little reaches the deep layers. Fractional microneedle radiofrequency overcomes this using insulated microneedles to spare the upper part of the skin and deliver radiofrequency energy precisely up to 4mm deep in the skin, resulting in faster recovery, higher efficacy and increased safety in treating acne scars.
Vascular lasers (such as pulsed dye lasers, yellow lasers, long-pulsed diode or NdYAG) target haemoglobin in blood vessels destroying them. They are useful for hypertrophic / keloid acne scars and fresh stretch marks. Intense Pulsed Light used for acne scar removal in Singapore together with special vascular filters can be used for similar purposes as well but is generally less powerful. The advantage of IPL is its minimal downtime -- you could get this procedure done during your lunch break and head straight back to work.
It is suitable for patients with mild to moderate acne scarring.
For best results on your IPL procedure, it will be good to avoid sun exposure in the days and weeks before and after the treatment.
Chemical Reconstruction of Skin Scars (TCA CROSS) uses the precise placement of highly concentrated chemical peel (such as Trichloroacetic Acid) to lift the base of deep scars.
In subdermal incision (subcision), surgical tools inserted under the skin via small needle punctures are used to release tethered skin scars stuck down to the deeper fascia by abnormal scar fibres.
Filler is then interposed to prevent the two layers from sticking back together during the healing process.
This subcision and filler process is suitable for scars with depressions, or pitted scars, with the main goal of improving your skin's appearance by releasing the fibrotic tissues responsible for the uneven skin.
Typically, these scars are thought to be the hardest to get rid of. Subcision happens to be the exact technique required to effectively correct these scars.
Usually, I would recommend subcision for patients with:
Excision is used for isolated ice pick scars or narrow boxcar scars. The scar is removed and the skin closed with either a skin graft or sutures.
Corticosteroid injections decrease over-active inflammation and collagen synthesis hence improving the appearance and symptoms of keloid or hypertrophic scars.
Dr. Wan believes that a combination approach is essential for effective acne scar removal treatments. The complex and varied nature of acne scars means there is no one-size-fits-all treatment. Only through a detailed examination of a patient’s condition and with a multimodal approach can a truly effective treatment protocol be designed.
The core factors Dr. Wan looks at when he assesses an acne scar patient includes:
Proper identification of the acne scars is key. Dr. Wan tailors his treatments based on the depth and the visibility of the patient’s scars and is keenly concerned with the final look of the patient post-treatment.
