Electrosurgical Resurfacing

Laser Skin Resurfacing

The use of lasers in dermatology has advanced rapidly over the past 30 years. Today, lasers have a broad range of dermatologic applications, including:

· removal or improvement of wrinkles, lines and other effects of aging and photoaging

· treatment of superficial brown pigmented lesions such as age spots, and deep pigmented lesions such as port wine stains and birthmarks

· removal or improvement of scars

· removal of some skin cancers

· removal or improvement of vascular moles

· removal of tattoos

· removal of warts

· removal of unwanted hair

The principal applications of lasers in facial skin rejuvenation are reduction or removal of wrinkles, lines and age spots, to "resurface" the skin.

The laser (L ight A mplification by the S timulated E mission of R adiation) is a "light pump". It applies principles of radiation physics to narrowly segregate light of selected wavelength and "pump" the light radiation to high intensity. These beams of selected wavelength can be varied in intensity and in the duration of emitted pulses.

For example, powerful, rapid pulses of the infrared-wavelength carbon dioxide laser can vaporize targeted skin. The pulses of the carbon dioxide laser can be directed toward resurfacing skin without bleeding. The benefits of laser skin resurfacing include bloodlessness, plus:

· reduced risk of infection

· precisely controlled surgical effects

· one-day outpatient treatment in many instances

After-effects and recovery times vary with different laser procedures. A dermatologist will explain the risks, after-effects and benefits of recommended procedures.

Lasers are powerful instruments and laser surgery should be performed only by a dermatologist or dermatologic surgeon with experience in the procedure.

An alternative to laser skin resurfacing is electrosurgical resurfacing, also called "cold ablation." This technique uses a micro-electrical radio frequency to deliver a pulse of energy to the skin, removing or improving superficial to moderate skin damage. The procedure has few after-effects, and recovery from mild to moderate swelling is usually complete within a month. Electrosurgical resurfacing offers the advantage of being applicable to most skin types and colors, without loss of skin pigmentation.

ablation – (хир.) удаление

superficial – поверхностный, неглубокий

moderate – умеренный, средний
