Laser treatment is used for acne on all parts of the body. Facial acne is very common, but people are also concerned about acne elsewhere on the body such as on the chest and back.
The process usually causes only minor discomfort. After the doctor spreads a protective layer of anesthetic gel, you'll only feel a brief stinging sensation that has been compared to an elastic band being flicked across your skin.
So, how does laser acne treatment work? The laser beam contacts the targeted layer of skin in pulses. The doctor can customize the treatment to match your needs by adjusting wavelength. The heat created when the laser is absorbed by selected body tissues, promotes the healing of your skin.
The heat of the laser shuts down or shrinks skin oil glands known as the "sebaceous glands". If you are familiar with laser hair removal, you will realize that this is similar to lasering hair follicles to slow down hair growth. Excess oil production causes a shiny complexion, clogs pores, and provides an environment for infection. Reducing oil production helps to reduce skin inflammation and prevents clogging of pores.
Laser heat also kills P.acnes,the bacteria that cause acne. This can be done directly or indirectly. The indirect approach is to remove the oil where these bacteria live. However there is also a blue light laser that has been designed to target P.acnes directly. When the bacteria take in the blue light, they perish. This technique is often used for eliminating adolescent pimples. Since blue light treats existing pimples but doesn't prevent them, another method is usually used with blue light to prevent future breakouts.
Besides these two treatment strategies, there are other laser acne treatment technologies currently being used in clinics and being developed in laboratories. The field of medical laser technology is very innovative. New ideas are being put into effect all the time. Types of lasers you may read about are carbon dioxide (C02) lasers, YAG, erbium, diode, Nd:Yg, and pulsed dye lasers. Erbium lasers were primarily developed for facial wrinkles but have also been used to eliminate pimples. CO2 and diode lasers are often selected for scar removal but can clear away blemishes as well. These are high intensity lasers which remove surface skin cells. A dermatologist who is a laser acne treatment specialist will be able to recommend the best treatment for you.
