The scientific background of lasers is rather complex. In 1917 Einstein theorized that electrodes could be stimulated to emit light of a particular wave length. It took 40 years, however, before scientists were able to put lasers on the path to becoming the powerful tools that they are today.
A laser is a device that creates a light beam, in a state of energy, to emit a precise wave length as an intense narrow beam.
Laser therapy has become more and more popular in the beauty industry, with the most common complaints being unwanted hair and unsightly skin pigmentation. Like all applications offered, a prospective client should investigate the pro's and con's of choosing this method to correct imperfections.
Unwanted hair is such a common problem and many methods have evolved to eliminate it, such as tweezing, threading, waxing, shaving and electrolysis. In the case of stubborn unwanted hair, laser treatment may be an option.
The preparation process varies and it may require both the therapist and client to wear a form of eye protection, in addition to masking off the surrounding skin with a gel. The unwanted hair will then be trimmed to a few millimetres above the surface.
A beam of highly concentrated light is aimed at the selected hair follicles. The equipment is adjusted to the colour and thickness of the hair, and the pigment in the follicle absorbs the light, destroying the hair. Because of the precision involved, the laser can target dark, coarse hairs, leaving the surrounding skin undamaged.
It is important that sun exposure be avoided for 6 weeks prior to treatment as temperature changes in the skin could jeopardise the results. After the procedure, a cold gel or anti-inflammatory product will be applied. Over the next month the treated hairs will fall out. Depending on the toughness of the hairs, repeat sessions will be recommended. Side effects, such as blister formation, are rare, but darker complexions could experience side effects which must be discussed with the therapist.
Laser treatment is available to treat troublesome veins, generally classified as varicose or spider veins. The heat produced by the laser destroys the walls of the veins, the body then naturally absorbs and excretes the dead tissue. In this way the abnormal veins are destroyed. Sufferers should thoroughly investigate options regarding vein treatments available, as many complications may arise which can be devastating.
Chloasma also known as melasma is a well-known women's problem brought about as a result of a hormone imbalance, especially during pregnancy, resulting in unsightly dark blotches on the face . The melanin producing cells are a mixture of those in both the dermis and epidermis, which may cause a challenge in treating and eliminating what is commonly called "the mask of pregnancy".
Treating pigmentation requires different wave lengths directed from the laser. Women having darker complexions [eg. Asians] should be more concerned than fair skinned women as it is a fact that the darker the skin, the darker the marks after healing. One commonly sees this after an acne condition heals. Research should be done to establish whether or not laser treatment is an option.
Depending on sensitivity, various treatments of the skin might leave redness, itching and a burning sensation. Creams and lotions having strong perfume should be temporarily avoided.
