The laser hair removal is very popular now, because of its efficiency and also because of the painless procedures of depilation. The laser technology is quite new and many questions appear concerning its use in cosmetology industry. A laser is a device that pulses concentrated light, making the hair dormant. There are different types of lasers used for depilation, depending on hair and skin color. Usually a single treatment is not enough for an efficient depilation, a set of procedures will give the best results. Also the laser treatment depend very much on the experience of the practitioner. This is why it is better to visit cosmetology cabinets that have experience on the market, not those with new and inexperienced personnel.

From the start we must analyze what is a laser in the dermatological use. It is a device that creates a beam of concentrated light of a single color or wavelength. The special dermatologic lasers make high-energy pulses that are concentrated on the necessary target. For example in the case of depilation, the laser is aimed to influence the melanin pigment, from the structure of hair. In order to depilate with the use of a laser, the energy beam is concentrated on the hair. The heat influences the hair follicle, which produces inflammation and stops the growing of the hair. As we said earlier for doing a hair removal with the help of a laser device a set of skills and experience are needed. This is due to the fact that the hair removal must be done without damaging the skin layer. In this case the laser has to be powerful enough to influence the hair, but not so powerful as to affect the derma. The hair removal is also influenced by other factors as the skin of the patient, the darker is the color of the skin the biggest is the probability of injury. This problem contributed to the apparition of three laser types that are used in different situations and skin colors. Another hair removal device, that has a similar action are the concentrated pulse light sources. These devices emit a light that has many colors. And because of this the complications and the outcome of the work with such tools, are not predictable. But an experienced and skilled practitioner can make an effective depilation avoiding the majority of risks.

For a good effect, a series of five treatments is advised, with an interval of four to eight weeks. For a long time effect, regular treatments are needed. Usually this maintainance treatment is done at a yearly interval.
