Acne Laser Treatment
Laser treatments are the fastest way to deal with scars and hyperpigmentation left behind when acne heals, but can also be beneficial for inflammatory acne. However, it’s not known to be particularly helpful for noninflammatory comedonal acne. The primary benefit of laser therapy, as well as the primary drawback of laser therapy, is that is has very precise effects.
Lasers produce intense monochromatic light, light that is limited to a very a narrow band of wavelengths. This light has no effect on some substances, and high-intensity effects on others. One setting might heat hemoglobin but have no effect on neighboring skin cells. Another setting might “melt” the melanin that causes deep pigmentation on the skin. A third might vaporize tattoo ink. Dermatologists use lasers to destroy specific substances at specific depths in the skin.
The primary effects of laser light in skin resurfacing are photothermal, heating a particular substance in the skin. The process of using laser to remove blemishes in the skin is known as photothermolysis, the breakdown of selected tissues in the skin. Continuous laser light would destroy tissues surrounding the target as the target tissue heated, so laser skin treatment is usually done with pulsed lasers.
