Vacuum Ultraviolet, also called VUV, is a short-wavelength UV light that has been used to help a wide variety of skin conditions. Nowadays, VUV light therapy is the best choice for people who are suffering from acne, psoriasis, eczema, persistent itching, skin cancers, and other skin problems caused by fungi, bacteria or viruses.
UV light can efficiently kill all bacteria, including drug-resistant bacteria and even so-called “superbugs” such as MRSA. Unfortunately, conventional germicidal UV light with wavelengths above 280nm is considered biologically harmful for human skin. Unprotected exposure to 280 – 400 nm UV light can lead to skin cancers and premature aging. It can also cause eye damage such as cataracts and eyelid cancers.
Researchers at the Columbia University Medical Center found that UV light in the range from 180 – 280 nm does not penetrate through the outer, dead layer of skin to harm the live skin cells below. However, it does penetrate and kill bacteria and viruses living on the skin.
VUV is UV light with a wavelength of 40 nm to 200 nm. Decreasing wavelengths correspond with higher frequencies and higher photon energy. What’s more, the shorter the wavelength of light, the shallower the penetration of the light into the skin.
The photon energy of VUV light is very high, so it can kill fungi, bacteria, viruses and cancer cells living on the skin effectively.
VUV photons set off a chemical reaction to create nitric oxide and ozone within cells and tissues. The actual therapeutic effects of nitric oxide depend on the amounts generated and the local concentrations achieved. VUV light therapy, proven to create proper nitric oxide, can kill fungi, bacteria, viruses and cancer cells effectively without damaging normal skin cells.
Healthy cells thrive on oxygen and can’t live without it. Disease-causing nasties like bacteria, fungi, parasites and microbes are anaerobic, and die in the presence of oxygen. Ozone is a powerful, activated form of oxygen. The ozone produced kills anaerobic organisms, without affecting the healthy cells.
Other common UV light may penetrate the dead skin cell layers to damage the DNA of normal skin cells, and eventually form a mass of cancerous cells. However, the dead skin on most of the human body can absorb VUV radiation almost completely. With the protection of dead skin cell layers, VUV light will not harm normal skin cells. So far there are no known side effects and complications associated with VUV light therapy.
In short, VUV light therapy may be safer and more suitable for the treatment of skin disorders than other popular UV light therapy.
