There are several different lasers employed for laser scar removal. These are frequently being developed; the lasers at this time are more precise and provide a a lot shorter recovery time than these used a decade ago.
The technology most commonly used involves the vaporization of the top layers of the skin, leading to a smoother appearance. Other laser scar removal types encourage the expansion of collagen underneath scars, in order that indented scars change into filled from below.
Right now's lasers come in several wavelengths, which affects how deeply they penetrate the skin. Because of this, they vary within the types of scars on which they're most effective. Listed below are essentially the most commonly used lasers used for scar removal
CO2 lasers are the oldest type used for removing scars. They're most frequently used on acne scarring, which they remove by vaporizing one layer of the skin at a time till the scar is flat against the rest of the skin, making the skin smooth.
Erbium, another older type of laser, can be used to treat acne scars, specifically those that are textured. The Erbium laser is designed to resurface the skin by removing the outermost layers. This type of laser boasts a decrease rate of problems than different types, and can be used on various skin types.
The Er:YAG laser system treats the edges of scars, as well as gentle to moderate acne scarring. It causes less damage than other types of lasers, and is considered more effective than CO2 lasers. It is usually more efficient on individuals with medium skin tones; other lasers are best used only on people with pale skin tones. Healing time and swelling are each reduced after present process laser scar removal with the Er:YAG laser system.
The Pulse Dye Laser (PDL) system is a shorter 585nm wavelength laser used to deal with both hypertrophic and keloid scars. It's effective at reducing the redness of scars because it is attracted to the hemoglobin in blood. The PDL system as also been used in the therapy of stretch marks.
The Q-switched laser is most often used for pigmented scars, particularly in individuals with darker skin. Pigmented scars have extra melanin, which is targeted by the Q-switched laser.
Because there are numerous completely different types of scars, there are lots of types of lasers to deal with them. Your choice of technology is dependent upon your skin type, the scar you are attempting to remove, and the doctor you choose.
These totally different applied sciences have been used below a number of brand names, so you'll want to ask your doctor concerning the type of laser technology getting used before you agree to the laser scar removal procedure.
