Skin surgery can get rid of ugly moles, brown spots or scars on your face. Hundreds of Singaporeans undergo skin surgery each year to improve their appearance.
Chemical peeling causes injury to the superficial layers of the skin and is believed to induce new collagen to form in deeper layers. Alpha-hydroxy acid (AHA) peels may help improve very superficial scars slightly. Treatment is easily tolerated and causes minimal disruption to the patient's schedule, but multiple treatments are needed. Deep scars do not improve with chemical peeling.
Laser resurfacing of the skin is a new treatment for acne scars. There are several laser systems available to resurface the skin in a controlled manner and the skin repairs itself with some clearance of the scars. In suitable patients, up to 40 percent improvement may be expected from a single laser treatment. However, there is a risk of complications such as prolonged redness, pigmentation and infections. It takes several weeks to recover from the surgery, but is generally much more effective than chemical peels.
Dermabrasion is an older technique for skin resurfacing but the principle is similar to that of laser resurfacing, using mechanical sanding to resurface the skin. It involves a certain degree of blood loss and requires greater skill on the part of the surgeon.
Scar revision: very deep, depressed scars will need excision (cutting) and stitching to correct the defect. Elevated scars (keloids) can be flattened by injecting small doses of steroids into them.
