Albert Einstein introduced people to the possibilities of using Laser light in 1917, but it wasn't until 1959 that a ruby crystal was used to produce a red light that would eventually treat red skin lesions.
Today, laser resurfacing is designed to treat a number of problems including sun damaged skin, wrinkles, some types of scarring, and acne scars. Because the application of a topical anesthetic is required, patients should arrive early to their appointment. Special protective eyewear is worn during the procedure. As the Laser passes over targeted areas, a slight burning sensation may be felt.
Afterwards, some swelling and redness will most likely occur. A gel-based dressing will be applied to the affected areas and a post-treatment checkup will be arranged to monitor recovery.
Types of Lasers
Since the mid 1990s, the Carbon Dioxide laser has been used to vaporize the top layer of skin off the epidermis and apply heat directly to the dermis. Another type, the Erbium Laser, penetrates less deeply and is often used to treat dark circles around the eyes. Other varieties include the Pulsed Dye Laser-Short Pulse, which is excellent for treating single blood vessels or spider veins, and the Pulsed Dye Laser-Long Pulse, which is best for treating large areas of redness. There are also three different types of Q-Switched Lasers.
The Lyra Laser
The Lyra laser represents the height of the evolution of the Laser Resurfacing industry. Using a deeply penetrating, therapeutic wavelength, the Lyra system is unique. Before Lyra, many people of different skin types could not take advantage of what laser resurfacing had to offer. Introduced in 1999, Lyra was approved by the FDA and Health Canada for use on all skin types. The Lyra system works as the light enters the skin but stays intact until it reaches a specific target, where it is immediately absorbed before turning to heat to destroy the problem, whether it be a hair follicle or spider vein.
