How does Laser Hair Removal Work?

October 20, 2009 by Jai Newman  

Electrolysis seemed to be the sole kind of long term or permanent hair elimination available just before laser and intense pulsed light (IPL) equipment joined the industry. Electrolysis will be still performed right now though it is unpleasant for the client and invasive to the epidermis, allowing for the opportunity of infection. Throughout the electrolysis treatment, a fine needle can be inserted into your hair follicle, dispensing an electrical current to be able to destroy the stem cells in the hair foillicle. Sad to say, this meticulous procedure will be conducted a single hair follicle at a time. Maintenance procedures are often essential for quite a while after the preliminary treatment.

On the flip side, with laser and IPL systems, hundreds of follicles of hair are treated each time depending upon the actual spot measurement (the size of the tip of the system supplying energy). These kinds of hair removal treatments are non-surgical and need just seconds to carry out rather than the many hours with electrolysis.

Laser + IPL Hair Removal and Melanin

A vey important factor in advance of a hair removal treatment will be the patient’s complexion type and hair coloring. Laser hair removal is actually determined by selective photothermolysis (using light and heat for damage of a hair follicle) together with melanin being the target chromophore (chemical grouping that produces shade). The main difference between the absorption of laser or light energy levels by melanin within the hair follicle and melanin inside the dermis determines the quantity of energy that can be safely employed without harming the skin.

Light skinned subjects with darker hair will be regarded as being the best clients for laser hair removal On the other hand, someone with very dark skin and gray or white hair, would have limited if any response. Since melanin in the hair shaft and follicle are the particular target source for laser and IPL hair removal procedures, it will be very important to individuals in the course of their initial consultation to not tweeze, wax or use any depilatory machine previous to laser hair removal. The person may, however, shave the region being treated (which often maintains the chromophore in the hair foillicle), or can use hair removal creams. Hair that is sticking up from the dermis will likely singe throughout a laser or IPL treatment which in turn causes a strong disagreeable stink as well as possible flares.

The particular Laser Hair Removal Proceedure

Nearly all instruments from a technical perspective act the same way while performing a laser hair removal procedure. The parameters on the device (joules, milliseconds, pulse, etc.) ought to be established based on the dermis evaluation and history carried out on the patient. It will be imperative for patients not to wear black apparel close to the place to be treated as the pigment inside the garments could possibly be absorbed via the laser or light and can lead to a burn. The patient needs to be advised to refrain from applying any body washes, tanning lotions, cosmetics, or any skin medications the day 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 treatment may be recommended.
