So How Does Hair Removal Work?
Electrolysis was the one method of long-term or permanent hair elimination readily available just before laser and intense pulsed light (IPL) systems entered the market. Electrolysis is still conducted today even though it may be agonizing for the patient and damaging to the epidermis, including the potential of an infection. Throughout the electrolysis procedure, a fine needle is put into your hair follicle, dispensing an energy current to be able to wipe out the stem cells inside the follicle. Sorry to say, this meticulous procedure will be carried out 1 hair follicle at a time. Upkeep procedures are often needed for quite some time following the preliminary procedure.
In contrast, with laser and IPL technologies, countless follicles of hair are taken care of each time depending upon the particular spot size (the size of the actual tip of the system delivering power). These hair removal treatments are noninvasive and take just moments to perform instead of the many hours of electrolysis.
Laser Hair Removal and Melanin
The main factor previous to a laser hair removal procedure can be the person’s skin tone type and hair color. Laser hair removal is actually dependant upon selective photothermolysis (employing light and heat for the purpose of destruction of a hair follicle) with melanin becoming the target chromophore (chemical grouping that produces color). The big difference between the absorption of laser or light energy levels by melanin within the hair follicle and melanin within the dermis determines the quantity of power that may be correctly applied without harming the skin.
Light skinned subjects with black hair are considered to be the perfect patients for hair removal Alternatively, someone with relatively dark skin color and gray or white hair, would have little if any result. Given that melanin within the hair shaft and hair foillicle are the objective source for laser and IPL hair removal treatments, it is important for individuals in the course of their first session to not tweeze, wax or use any depilatory item previous to laser hair removal. The person can, however, shave the region to be treated (which usually maintains the chromophore within the hair foillicle), or can use hair removal creams. Hair which is protruding on the dermis will likely burn during a laser or light treatment which causes an unpleasant smell and possible flares.
A Laser Hair Removal Proceedure
The majority of devices theoretically function exactly the same way while performing a hair removal procedure. The variables on the system (joules, milliseconds, pulse, etc.) ought to be established based on the skin tone analysis and background carried out on the individual. It will be crucial for clients not to wear darkish clothing close to the area to be treated as the pigment in the garments could possibly be absorbed via the laser or light and can lead to a burn. The individual should be instructed to avoid using any body washes, lotions, makeup products, or any skin medicines the morning of the treatment. Some patients may prefer to have a topical anesthetic applied prior to the procedure. If any residue of the anesthetic remains, it should be wiped clean from the skin. A spot test, or patch test, should be performed on the intended treatment area. Several procedures are required at monthly intervals for an optimal outcome and a yearly maintenance procedure can be recommended.
