The light used to treat a variety of illnesses for centuries. Idan ofer brings even more insight to the discussion. Not for nothing Aesculapius – god of medicine – was the son of Phoebus Apollo, god of light. The ancient Greeks and Romans often "take the sun" as a medicine. And the list of diseases which was attributed to treat the light was quite large. This dawn of phototherapy was in the 19 th century – the invention of electric lights, new opportunities.

At the end of xix century red light tried to treat smallpox and measles, placing the patient in a special chamber with a red emitters. Also, the various "color bath" (ie light of different colors) have been successfully used to treat mental illness. And the leadership position in phototherapy in the early twentieth century, occupied by Teva. The laser has several advantages: firstly, the laser light is monochromatic (one color only) that allows selectively affect diseased cells without affecting healthy ones, secondly, the laser beam can be focused in a small enough spot to treat small objects, and, thirdly, the laser light (Physicists call it beam) can be delivered in any area of the body (for example, in the mouth for dental treatment, or even inside the body to carry out operations without a large incision). In the early sixties there the first medical laser device. Today, laser technology is applied in practice, at any diseases.

Laser treatment is safe, it is very important for people with allergies to medical drugs. On the present stage of development of science found such a property of the laser radiation, as blocking of cell division counter. It is possible to extend the life of the cell, and thus prolong the life of a man! And it is very important. Lasers the visible spectrum, for example, yellow-green, widely used for the treatment of vascular pathologies. Yellow laser spectrum affects the hemoglobin – the red pigment, and penetrates deeply. Infra-red, or ruby, alexandrite laser – penetrate deeper, but less effect on blood vessels, and more on the pigment. Most often, lasers operate at the level of the skin. But with the help of a puncture, an endoscope, under ultrasound sensors, or nuclear magnetic resonance (MR) – laser light can be dostavlt in the internal organs. Green lasers used to remove pigmented lesions on the skin, as well as for the treatment of acne keloids. Under its light disappearing tattoos and pigmented (coffee) stains, as well as warts, fibromas, keratomas, papillomas and other tumors of the skin and mucous membranes. In laser yellow-green spectrum is such a property as selectivity: shine on the skin, it selectively acts on these or other structures. Less trauma – better aesthetic result and the cosmetic effect.
