The main method for laser acne treatment uses a beam of light that penetrates the skin and targets the sebaceous glands. These are glands that produce oil to lubricate your skin and hair. A primary cause of acne is too much oil--so the laser is used to weaken the oil-producing glands. As a result, your skin becomes less shiny and pores are no longer clogged.
Another strategy is to target the bacteria that contribute to acne. These are called "Propionibacterium acnes" or "P.acnes" for short. These bacteria naturally live in the skin, but in the presence of excess oil they multiply and cause inflammation. A special laser has been developed to reduce the number of these bacteria to normal levels. What happens is this: When the laser light is absorbed by the bacteria, the bacteria perish. You may wonder why we have to use a laser for this purpose. Shouldn't proper washing be sufficient? Unfortunately not-- since the bacteria live under the surface of the skin, they are hard to remove with normal washing. Doctors prescribe antibiotics to fight these bacteria, but drugs are not always effective. Some people prefer to solve their skin problem with a few treatment sessions rather than being saddled with taking a daily medication.
The main distinction between different types of lasers is the wavelength of the laser beam. Wavelengths used in laser acne treatment can be from 450nm to 1450nm. Different wavelengths are good for different types of problems. For example, a short wavelength is good for excess bacteria and a longer wavelength is used to slow down the sebaceous glands. Modern laser devices are usually adaptable, being able to address both of these common causes of acne.
As you research treatment approaches, you will come across many kinds of lasers. For example, types you will hear about are erbium, carbon dioxide (C02), diode, pulsed dye, and blue light lasers. Blue light lasers are particularly effective in dealing with excess P.acnes. New types and variations are being invented and improved all the time.
Ablative lasers are very good for removing old acne scars. They smooth and refresh the skin surface by vaporizing the thin outer layer of skin cells.
The versatility of laser technology has made it an excellent tool for all aspects of acne treatment. Laser acne treatment is capable of healing pimples and inflammation, preventing future eruptions, and removing scars. The procedure is accomplished in several brief sessions with minimal discomfort. Any skin sensitivity following treatment is not serious and is only temporary.
