What is Laser Skin Resurfacing?
The word laser is an acronym that stands for Light Amplification by Stimulated Emission of Radiation. A surgical laser, such as the CO2 laser, is a beam of light capable of removing unwanted tissue, such as scarred, lined, wrinkled, and otherwise imperfect skin. The laser vaporizes skin cells by emitting bursts of radiation that are absorbed by water in these cells. Laser light penetrates to a very precise, controlled depth, making the procedure safe and predictable while reducing the risk of scarring or pigmentation problems. Laser skin resurfacing is bloodless and is performed right here in our office, under light sedation. As a result of this treatment, you are left with more natural-looking skin.
Laser resurfacing can be used as an alternative to chemical peels and dermabrasion. This technique offers less pain, a faster recovery time, and, in most cases, is also less costly.
Dr. Urban utilizes two types of ablative lasers: a Fractional CO2 laser and an Erbium YAG laser. The CO2 laser can be used for deep resurfacing, while the Erbium YAG laser is used for superficial rejuvenation.
- CO2 — The carbon dioxide (CO2) laser uses infrared light to vaporize the surface layer of the skin, prompting the cells to regenerate and replenish the surface layer with healthy, new skin. The fractionated CO2 laser is capable of treating mild to moderate wrinkles, fine lines, acne scars, sun damage, skin texture irregularities, and pigmented lesions. The CO2 laser will direct a grid pattern of tiny pulses of light at the skin. Each pulse delivers a column of energy that can reach the skin’s dermal layer. Unlike 100% ablated CO2 lasers, a fractionated laser only resurfaces a predetermined portion (25-85%) of the skin surface. CO2 laser skin treatment stimulates a natural renewal process of the body’s own collagen. Also, because the laser beam has been fractionalized, small areas of untreated skin will be left between the treated spots. The healing process is accelerated by strategically performing the procedure in this manner.
- ER YAG Laser — The Erbium YAG laser (ER-YAG) emits a beam at 2490 nm, which is absorbed more readily by water present in the skin, allowing for less heat damage to the surrounding tissue. The ER-YAG does not penetrate the skin as deeply as the CO2 laser, but it allows for gentler, more precise collagen targeting. The Erbium YAG laser is capable of treating atrophic acne scars, photo-damaged skin lesions, mild to moderate facial wrinkles, and uneven pigment seborrheic keratosis. During the treatment, epidermal cells are removed while the dermal tissue receives gentle healing to stimulate collagen renewal. Extended ablation technology’s precision and minimal residual thermal damage accelerate the re-epithelialization process, leaving no demarcation line. This allows for the treatment of small problem areas, providing a full laser facial with minimal downtime and outstanding results.
