Laser Scar Revision at Zoe

Laser Scar Revision is a nonsurgical procedure to improve the appearance, symptoms, texture & pliability of all scars with lasers. Laser Scar Revision utilizes photothermal energy to target intra and extracellular structures within the scar tissue to stimulate the remodeling of dermal collagen and elastin and also causes neo epithelization of targeted scar tissue. Ablative lasers are most important tools for non surgical scar revision.

Most commonly used ablative lasers are CO2 and Er:YAG Lasers. More recently, fractional ablative laser resurfacing (Fractional CO2 laser treatment) & (Fractional Er:YAG laser treatment) has emerged as a popular treatment modality for atrophic and surgical scars because of better patient acceptability and tolerability due to reduced downtime. In Fractional Ablative Laser Resurfacing, columns of thermal damage called microscope thermal treatment zones are separated by surrounding untreated skin. This results in rapid re-epithelization and reduced downtime as only fraction of the skim is treated. The micro thermal treatment zones also allow fractional lasers to penetrative the skin more deeply than the fully ablative lasers. Studies have also shown significantly superior outcome with fractionated CO2 and Er:YAG lasers compared to fully ablative CO2 & Er:YAG lasers for surgical and traumatic scar revision.

Frequently Asked Questions

Any patient with atrophic, hypertrophic or keloid scar who desires an improvement in scar appearance and texture are candidates for laser Scar revision. E.g.: Burn scar, Acne scar, Traumatic scar, Surgical scars like post thyroidectomy scar in the neck.

Scar in any part of the body from face to feet can be treated with the latest technology of fractional lasers. E.g.: Acne scars in the face, Post thyroidectomy scar in the neck, Any scar in the breast post lumpectomy, Post fibroadenoma excision, Scar in the abdomen post caesarean section.

Usually 6 sessions are required for Laser Scar Revision but may range from 4 sessions for new scars to more than 10 sessions for older scars.

The interval between sessions of laser scar revision varies between 4 to 6 wks.

Adverse effects with Fractional CO2 & Er:YAG are generally transient and less severe compared to fully ablative lasers. Common side effects are: Erythema, crusting, burning sensation, edema, bruising which are transient. Persistent Erythema and post inflammatory pigmentary changes are less common complications

Laser Scar Revision is not painful and is well tolerated by all the patients as a numbing cream is topically applied over the treatment area 30 mins prior to the procedure. Patients might though feel a mild stinging sensation at the onset of the procedure.

Laser scar revision in cases of traumatic and surgical scars is very effective especially when resurfaced within 6-10 wks after trauma or surgery or even immediately after surgery; although very good results can be achieved also in cases of older scars.
