<p>Acne therapy deals with the treatment of the disease. Blue light therapy involves exposing the affected area to a low-intensity blue light source that is used to kill bacteria that are responsible for the disease. Some side effects of this type of treatment include temporary redness and dryness in the treated area. There is a newer light therapy that combines blue and red light. This newer therapy is more effective than blue light alone. There is also the pulsed and heat energy therapy. When these two therapies are combined, they can kill bacteria as well as shrink the sebaceous glands and thus decrease sebum production. A side effect for this type of acne therapy is redness in the treated area. Laser treatment involves laser resurfacing and fractional laser therapy. Laser resurfacing is form of laser acne treatment that involves the use of a laser on the scarred part to burn off the top layers of the skin. Removal of the top skin triggers the inner layers of the skin to start immediately cell and collagen reproduction in a bid to replace the missing skin.
Fractional laser therapy involves the use of a laser to penetrate the inner layers of the skin without causing any damage to the top layer of your skin. You can go for this procedure when you have a protruding or a bumpy scar. Burning off the underlying layers of the skin helps to smoothen and make level the scarred area with the rest of your skin. This type of acne therapy is more effective than laser resurfacing. It is however more costly and lasts longer as compared to conventional laser resurfacing.</p>
