Blue Light Acne Treatment – A New Remedy?

Some experts claim that laser and light therapy is this century’s alternative to traditional treatments. These technologies have been successfully applied to treating acne and other skin diseases. Many acne sufferers who were disappointed with all other methods have found a solution for their problem in blue light acne treatment.

Benefits of Blue Light Acne Treatment

Blue light acne treatment focuses on eliminating P. acnes, the bacteria that causes to acne eruptions. This bacteria pumps out some molecules called porphyrins. When these molecules are exposed to blue light, they release free radicals that kill the bacteria.

Blue light acne treatment has several benefits in comparison to other therapies:

* It is a totally natural and has no side effects.

* It is safe to use daily and for all ages.

* Unlike other light therapies, it doesn’t contain UV light that can hurt your skin.

* It is painless and you can do it in your own home.

Research Data

Data from clinical trials on blue light therapy has revealed that is a promising acne treatment. Patients involved in the studies have received the blue light acne treatment in several session, each lasting about 15 minutes. Many of them, but not all, have registered significant improvement after the treatment, with approximately 55% clearance. Side effects were only mild and included short-term pigment changes, dryness and swelling of the treated area.

Taiwan: Thirty-one patients with facial acne on both sides have received blue light acne treatment only on one side, while the other has received no treatment at all. The therapy was given twice a week for four weeks. In the end, it was concluded that blue light acne treatment is effective unless the patient suffers from cystic acne, which often worsens when treated with blue light.

United States: Twenty-five patients suffering from inflammatory acne were treated with blue light therapy on one side (8 sessions in 4 weeks) and with clindamycin on the other (twice a day for 4 weeks). In the end, researchers compared the results for the two treatments. The side treated with clindamycin showed an approximately 22% improvement, while the one treated with blue light therapy showed around 40% improvement. However, after 8 weeks of no treatment, the clindamycin side had maintained the results better.

Israel: Three separate studies on 10, 13 and 25 patients suffering form inflammatory acne were conducted in order to measure the effects of blue light acne treatment. In all of the three studies, over 80% of all patients responded well to the treatment, showing between 59% and 67% improvement.

Japan: 30 patients suffering from mild to moderate acne received a blue light acne treatment twice a week for up to five weeks. For 80% of all patients, the lesions decreased by approximately 64%. The rest of them experienced negative or no effects.

Unfortunately, the number of individuals involved in these research studies is too small. Generally, clinical trials aimed to test new treatments enroll hundreds or even thousands of patients. Considering the small numbers involved in the blue light acne treatment studies, no statistically valid conclusion can be drawn. However, these studies do reveal that blue light therapy has positive effects on some individuals suffering from acne. It gives best results for inflammatory acne and may not be safe to use on patients with cystic acne lesions.

What happens to bean plants grown under red, blue, and green light?

If you have five lima bean plants, one grown under natural light, one under red light, one under blue light, and one under green light, how would each plant grow? And which color of light is most effective for bean plant growth: red, blue, or green light?

Plants need the full spectrum to grow well. With any limit in the spectrum they will suffer a drop in growth rate as all parts of the visible range can contribute to plant growth but if light is limited they will struggle.

Plants respond most to light in two peak ranges for photosynthesis. The first peak is in the blue range (430 to 450nm) and the second peak, is in the red range (680 to 700nm) but they respond across the spectrum even in ranges beyond the visible. In between these two peaks, in the green spectra, the absorbance rate dips.

Photosynthesis and growth regulation spans 300-800nm. Plants use light and changing light duration to keep themselves regulated to the changing seasons.

Vegetation or foliage plants grow best under bulbs emitting blue spectrum light. Blue is 400-475nm because chlorophyll peaks at 430 – 470nm plants use this part of the spectra.

Flowering plants require light from a red-orange emitting grow light. Red visible spectra is 580-700nm but plants also need the near infrared (~730nm) to regulate them to flower & fruit properly.

Green light is reflected so is not critical for growth.
