Reducing Acne Is Going to be Easier With Blue Light Acne Treatments

One of the more effective methods to get rid of acne is with blue light therapy. You really need to understand why blue light is so effective against acne.

Many adults and around 85% of adolescents have suffered acne outbreaks. Pimples and other sores result from pores that become plugged by a mass of skin oil (sebum) and dead skin cells. Once a pore becomes plugged the bacteria within in the pore begin multiplying and infect adjacent tissue. This results in the redness and tenderness often connected with acne.

Generally acne prevention strategies involve three steps. First, cleansing is helpful to remove surplus skin oil over the surface. A mild anti-bacterial cream or gel is next used to kill surface bacteria. Finally a mild exfoliant cream or gel is employed to make it easier to loosen dead skin cells so they can be washed away. By doing this the possibility for clogging the pores is greatly reduced plus the chance of acne is minimized.

Once pores become plugged they form whiteheads or blackheads. These are tiny lesions and are different as a result of the position of the clog. With a blackhead, the clog is near the surface where it can become oxidized and darken. When the clog descends a short distance into the pore upper portion of the pore can close up over the clog and the clog remains light colored and forms a whitehead.

Cells encircling the pore become red, irritated and constitute a pimple because the bacteria within the clogged pore begin multiplying. The blemish can become more severe if the infection spreads beyond the pore. As an example, pressure over a pimple may force infected oil further down into the sebaceous gland or even into deeper skin layers and develop into a cyst.

You can see how important it is to kill the bacteria at the location of the pimple. With the bacteria gone, the cells will no longer be irritated and can begin to mend. Severe acne is often taken care of with systemic medicines like oral anti-biotics. Most milder acne outbreaks may be dealt with effectively by therapies applied locally.

One such therapy is acne light treatment. While sunlight has always been know to help acne, scientists examined specific colors of the spectrum to determine specifically the range of colors that are actually helpful. One early investigation found that light within the blue-violet color range was especially useful. This color range affects an organic compound within the acne bacteria. This porphyrin releases a signlet oxygen that eventually kills the bacteria.

Because acne bacteria multiply rapidly, three treatments on consecutive days are often necessary to kill all the bacteria in a blemish. With the bacteria gone, the irritation is removed and the curative process can take place to restore the normal skin condition.

The blue light may be delivered by lasers, light-emitting diodes (LEDs), fluorescent lamps, or even bright full spectrum light. Numerous dermatologists use the Dusa Blue Light which is just like an array of fluorescent lights that emit light with a 400nm wavelength. Frequently your dermatologist will apply aminolevulinic acid (brand name Levulan) to affected areas prior to the blue light therapy. The Levulan is photosensitive and exposed to blue light helps damage particular skin cells.

A single therapy session in a dermatologists office may cost $200 or more. But, there are a variety of devices you may purchase to be used right at home that many people have found helpful. You can find numerous devices on the market ranging is price from around $40 to several hundred dollars.

Keep in mind that blue light acne treatment requires several treatments to kill the bacteria and several days for the skin to heal. So, this is not an overnight process. But, compared to treatments like benzoyl peroxide, many people have found blue light acne treatment to be less irritating to the skin and more effective at eliminating acne.
