Hair follicles in the treatment area are identified and marked off for removal by the surgeon-technologist. The laser beam of concentrated light energy is calibrated to precise frequencies or radiation-energy levels to be 100% safe to the patient. The pulse of light energy is targeted at the hair follicles for sufficient time to delimit functioning of the hair follicle. In so doing, the hair follicle effectively stops the biological process of protein synthesis related to hair growth, therefore no new hair is produced from those follicle sites.
The amount of energy directed through the laser is sufficient to created the desired effect, but not so excessive to either cause any excess heat build up to occur or to create any health risk to the patient. Only the hair follicle is destroyed, which is the treatment focus. Skin remains healthy and unaffected.
Lasers used for laser hair removal utilize various energy frequencies, from the cooler blue spectrum through the green spectrum on to the yellow spectrum, depending upon the application need.
Laser technology has been utilized for many years in a range of applications, from hair removal to controlling the delivery of munitions in warfare situations. Lasers provide control and increased accuracy in all applications, since the underlying directionality and dimensions are those of the light photon itself, an especially discrete unit of energy.
How Much Pain
To Expect Similar to any other cosmetic surgery procedure, laser hair removal is creating surface bodily changes at some cost of discomfort to the patient as the price for obtaining the desired effects. For many patients receiving laser hair removal procedure, the treatment feels more like a localized "heating up" of the skin, with no other recognizable sensation. For others with very low pain and discomfort thresholds, the technologist can apply a topical anesthetic to the treatment area in order to de-sensitize the region while treatment occurs.
Bottom line is that pain and discomfort levels vary enormously based on the widely ranging differences in people to procedures of any nature. In general, underlying health along with a positive outlook towards the laser procedure combine to steady most patients. Furthermore, the protection of consumers is directly regulated by the FDA which oversees the market introduction of any health care technology such as lasers in order to safeguard the health of the public. Accordingly, lasers are designed to be safe, focused in treatment applications, relatively low cost and not creating health risks of any consequence.
After receiving a laser hair removal procedure, patients will notice a redness in the treatment area. Any pain or discomfort will be mild as well as transitory rather than severe and terminal. There's no body of literature or field data to show any meaningful side-effects other than temporary redness.
