An FDA-approved procedure for moderate acne vulgaris. Blue light therapy uses light in a specific wavelength (blue) to kill the bacteria that causes acne (propionibacteria acnes).
Blue light therapy can be used on its own, but is often combined with an agent that makes the skin more receptive to the light treatment.
The procedure itself is simple — the client sits under the blue light for a few minutes. If a photosensitizing agent is used, it is applied prior to the blue light treatment. Several treatments are needed, usually spaced out over several weeks.
Side effects are mild swelling, redness, dryness, and temporary changes in skin color.
Blue light is often used after other treatments have been tried unsuccessfully. Many people find blue light improves acne, although not everyone sees results. Some studies have shown that nodulocystic acne may actually worsen after blue light treatments.
Blue light therapy acne treatment has recently been approved by the FDA to treat mild to moderate acne. The development of acne blue light therapy has had significant benefits for those who have not responded well to other of methods of treating common acne.
Common acne, or acne vulgaris, is caused when oil produced by the sebaceous glands in the skin is trapped in pores. The P. acnes bacteria thrive in this trapped oil, and the pore then becomes inflamed and turns into a pimple. A pimple may then develop into a whitehead or blackhead.
Only recently has blue light therapy acne treatment become available for use on a wide basis by dermatologists and others. The acne blue light therapy works by killing the P. acnes bacteria. The light may either be used alone or in conjunction with a topical treatment. The acne blue light treatment has been shown to be effective in treating active acne lesions as well as other sebaceous glands that are not actively producing acne lesions.
Blue light therapy is a modern discovery in the fight against acne. Unlike other acne treatment solutions such as medicated creams and expensive dermatological procedures.
