Skin Clinic Q&A: So How Does Hair Removal Work?
Electrolysis appeared to be the sole method of long-term or permanent hair elimination available before laser and IPL systems came into the industry. Electrolysis may be still conducted today even though it is agonizing to the client and invasive to the epidermis, allowing for the opportunity of an infection. Throughout the electrolysis treatment, a fine needle will be introduced into the hair follicle, delivering an energy current to eliminate the stem cells in the hair follicle. Unfortunately, this slow method could be performed a single hair follicle at a time. Additional treatments are often required for several years after the primary treatment.
On the flip side, with laser and IPL concept, many hundreds of hair follicles are taken care of at a time depending upon the particular spot dimensions (the size of the tip of the machine supplying power). These kind of hair removal treatments are non-invasive and need just seconds to carry out rather than the many hours with electrolysis.
Laser + IPL Hair Removal and Melanin
The key factor prior to a hair removal procedure can be the patient's complexion type and hair coloring. Laser hair removal is actually dependent on selective photothermolysis (employing light and heat for destruction of a hair follicle) along with melanin becoming the target chromophore (chemical grouping that generates shade). The big difference between the absorption of laser or light energy levels by melanin inside the hair follicle and melanin inside the skin determines how much energy which might be safely utilized without injuring your skin.
Light skinned clients with black hair tend to be regarded as the ideal clients for laser hair removal On the other hand, a client with very dark skin color and gray or white hair, can have limited if any response. Because melanin within the hair shaft and hair foillicle are the specific source for laser and IPL hair removal procedures, it is important for individuals during their initial appointment not to tweeze, wax or use any depilatory gadget ahead of laser hair removal. The person might, however, shave the area to be treated (which often saves the chromophore in the follicle), or may use hair removal lotions. Hair that is protruding on the dermis may burn throughout a laser or light treatment which in turn causes an disagreeable odor as well as possible flares.
A Laser Hair Removal Proceedure
Nearly all equipment from a technical perspective work exactly the same while performing a hair removal procedure. The variables on the device (joules, milliseconds, pulse, etc.) ought to be established according to the complexion evaluation and background carried out on the individual. It is essential for patients not to wear dark apparel close to the region to be treated since the pigment inside the garments could potentially be absorbed by the laser or IPL and can result in a burn. The patient needs to be instructed to avoid using any body washes, creams, cosmetics, or any skin medications the afternoon of the procedure. 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 treatments are required at monthly intervals for an optimal outcome and a yearly maintenance procedure may be recommended.
