There are several totally different lasers employed for laser scar removal. These are frequently being developed; the lasers at the moment are more exact and offer a a lot shorter recovery time than those used a decade ago.
The technology most commonly used entails the vaporization of the highest layers of the skin, resulting in a smoother appearance. Other laser scar removal types encourage the expansion of collagen underneath scars, in order that indented scars turn out to be stuffed from below.
As we speak's lasers come in numerous wavelengths, which affects how deeply they penetrate the skin. Because of this, they vary in the types of scars on which they are most effective. Listed here are essentially the most commonly used lasers used for scar removal:
CO2 lasers are the oldest type used for Pigmentation
removing scars. They're most often used on acne scarring, which they remove by vaporizing one layer of the skin at a time till the scar is flat towards the rest of the skin, making the skin smooth.
Erbium, one other older type of laser, is also used to deal with acne scars, specifically these which can be 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 other types, and can be utilized 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 different types of lasers, and is considered more effective than CO2 lasers. It's also more effective on individuals with medium skin tones; different lasers are greatest used only on people with pale skin tones. Healing time and swelling are both 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 each hypertrophic and keloid scars. It's effective at reducing the redness of scars because it is drawn to the hemoglobin in blood. The PDL system as additionally been used in the remedy of stretch marks.
The Q-switched laser is most often used for pigmented scars, notably in people with darker skin. Pigmented scars have excess melanin, which is focused by the Q-switched laser.
Because there are various different types of scars, there are many 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 completely different applied sciences have been used beneath several model names, so you should definitely ask your doctor concerning the type of laser technology being used earlier than you agree to the laser scar removal procedure.
