Laser light of a certain wavelength is specifically absorbed by the pigment Melanin. This pigment is present both in our hair as well as skin, eyes and other areas. Skin hair has a high concentration of Melanin, it absorbs more of the laser light, which is then converted into heat energy that travels down to the hair bulb below the skin.
The heat generated is just enough to destroy or weaken the hair bulb, which results in decreased/no hair production. Repeated sessions are required at an interval of 4-6 weeks. This is because all the hairs are in different parts of the hair cycle. This means not all the hairs are at its optimum condition to be targeted by the laser at a certain given time. A minimum of 6-8 sessions is required for long-lasting results.
Not all patients are ideal candidates for LHR. This is why a careful assessment is important prior to starting treatment.
In our clinic, we use Long-Pulsed Nd:YAG as this is the safest and most effective laser for the skin type in our region. The Candela GentleYAG Pro hair removal systems are the most popular devices in the world because of its safety profile, efficacy and patient comfort.
