Laser Hair Removal
Laser hair removal uses light energy to remove hair from the roots. Laser removal has gained popularity because of the different advantages it offers when compared to other hair removal methods. This technique is now widely accepted in the dermatology community as one of the most effective hair removal methods as it can achieve permanent results using the latest technologies.
It uses selective photothermolysis (SPTL) which targets tissue by matching intense light wavelengths with the timing of a pulse. The outcome is specific to the targeted area whilst having a minimum effect on the area around the light. The laser heats dark target matter, melanin, in the area that causes hair growth – the hair follicle. As the lasers target the hair follicle, they avoid the rest of the skin. The light is absorbed by dark objects or matter quickly and with greater intensity. The dark matter in skin is called chromophore. Melanin is the primary chromophore in skin and helps to provide hair and skin with its individual colour. In hair there are two kinds of melanin, one which gives hair a dark colouring and one which gives hair a light colouring. Laser photons are only able to be absorbed by dark hair effectively. For this reason, lasers works best with dark coarse hair rather than light thin hairs. The ideal combination for laser hair removal is a combination of dark hair and light skin. However, new lasers can now target dark hair with dark skin. Initial number of treatments can range from three to eight, though most patients require a minimum of more.
Laser hair removal has a number of advantages. First, it is very safe when done by a licensed professional. Also, effects of laser hair removal can last very long and can lead to permanent hair removal. If the hair does grow back, the hair will be lighter and thinner. Lastly, the procedure is relatively pain free, but this would still depend on the person’s skin sensitivity and tolerance to pain.
As with other beauty treatments, there can be adverse effects to laser hair removal. It can cause skin itching, irritation and redness. Depending on the person, the procedure can be painful. However, most clinics have creams that could reduce this pain. Additionally, if the laser settings are not appropriate to the patient, it can lead to hypo- and hyper-pigmentation. It can also cause skin discoloration, acne flares, scab formation, allergy and infection. The cost of treatments can also be quite expensive, running into hundreds of pounds for treatments.
Laser hair removal is popular because of its efficiency and speed, though it would still depend on the skills of the laser operator. It is best to seek a skilled and qualified professional to administer laser hair removal treatment for optimum results. It is also best to seek a physician’s advice if any adverse effects are caused by the treatment.
