Acne laser treatments usually work by:
- reducing oil production,
- speeding up the growth of new skin cells
- the removal of dead skin cells
- fighting bacterial infection
Now, the laser treatment is going to reach the deeper layers of skin without harming the skin's surface. Laser systems are thought to damage the oil glands making them produce less oil. These therapies can also improve skin texture and lessen the appearance of scars, so they may be good treatment choices for people with both active acne and acne scars.
Diode laser treatment
Diode lasers can destroy glands in the thick middle layer of skin, without harming the outer layer of skin. It may be painful, but the pain can be controlled with analgesics applied to the skin before treatment. Side effects aren’t bad: a little temporary redness and swelling of the treated areas.
How about Light Therapy?
Blue light therapy
Exposing the skin to a low-intensity blue light source is believed to work pretty well. It’s a painless procedure however ongoing treatment is necessary for best results. Possible side effects of blue light therapy include temporary redness and dryness in the treated areas. A newer type of light therapy that includes a combination of blue and red light may be better than just blue light alone.
Pulsed light and heat energy therapy
Pulsed light and heat energy is thought to destroy acne and decrease oil production. The Food and Drug Administration approved an acne therapy that combines pulses of green-yellow light and heat to treat mild to moderate acne, including inflammatory acne. Side effects of this therapy include temporary redness in the treated areas.
Laser acne and light therapy treatments can be pretty pricey and may not be covered by your insurance company. |
