Laser Hair Reduction
What is Hair Reduction?
Hair reduction is the removal or the reduction of unwanted hair on a specific part of the body using one among a variety of systems. Most commonly used systems are light-based technology, like lasers and intense pulsed light (IPL), Long Pulse 755nm Alexandrite laser & 810nm Diode.
How does Hair Reduction work?
The absorption rate of melanin is the single most important factor in hair reduction. If the absorption rate is too high, it can damage the skin and increase the risk for burns and uncomfortable treatments. If it is too low, the hair follicle will not absorb enough energy to effectively destroy the hair follicle. The 808nm wavelength in the Vikini and the Epilia diode lasers, as well as the cut-off filter system in the CBL IPL & Noblex Long Pulse 755nm Alexandrite laser deliver ideal absorption coefficients and allow good control during treatment.
The thermal energy absorbed by the melanin in the hair shaft and the hair follicle heats the tissue up to 70C, which then allows for the permanent destruction of hair growth.
What is the best Hair Reduction system?
The Vikini is an 808nm diode laser that is specifically designed for hair removal. The 808nm wavelength is highly absorbed by the melanin chromophore that is present in hair and hair follicles. By selective photothermolysis, the thermal energy effectively destroys the hair follicle without damaging the adjacent tissue. This prevents regrowth of the unwanted hair leaving skin smooth and silky.
The Vikini has perfected the 808nm diode laser technology and improved this with a powerful contact cooling system on the hand piece, ensuring maximum safety and comfort is achieved on every treatment.
Similarly, the CBL has surpassed traditional IPL systems in terms of effectiveness and comfort by incorporating an adjustable cooled sapphire function delivering controlled temperature control for undiluted energy delivery on the 700nm cut-off filter. This effectively gets rid of the most common complaint during hair reduction – discomfort.
Theories behind Hair Reduction
Human hair grows in a cycle of 3 phases: anagen (growth phase), catagen (transitional phase) and telogen (resting phase). During hair reduction treatment, thermal energy is delivered to the hair follicle to destroy it. Only hair in the anagen phase will be effectively removed as this is the point when the hair is at its largest, with the most melanin content and is attached to the root. Hairs in the other stages of growth are eventually removed once they are on their anagen phase.
Repeat treatments are normally necessary in order to remove all hair. It is normally done through a program of 5 to 6 times based on a client’s skin and hair type. More treatments may be required for thinner or light-colored hair as they would naturally contain less melanin.
