Laser Skin Resurfacing
Evolution of Laser Skin Resurfacing
Laser resurfacing is a technique used to reduce acne scarring by “selective phototheromolysis.” This concept employs the use of specific energy fluence, wavelengths, and laser time, in order to reach specific dermal and epidermal layers. Two different types of popular ablative lasers are the C02 (10,600 nm wavelength) and Er:YAG (2940 nm wavelength) lasers. These lasers penetrate deeper than superficial skin resurfacing lasers such as Pulsed Dye Lasers, which are commonly used for skin discoloration and other superficial blemishes.
The Sciton Erb:YAG laser is an ablative laser, the chromophore (affected cell component) of which is water. The depth of tissue vaporized is roughly 3-5 micrometers. Using the monitor display, the provider can adjust the ablation and coagulation depth. After resurfacing, the skin may become scabbed and weep, and it is important to keep the skin hydrated with a hydrated healing ointment. The epithelial surface will regenerate at around 1 week, but redness may persist for up to 3-4 weeks. The Sciton Erbium laser causes less heat damage than other CO2 lasers, which can reduce the postoperative social down time required for redness to resolve.
