Laser / IPL / LHE Hair Removal

Scientific studies in the early 1990s proved that lasers were an effective method of removing unwanted hair, and the first machine approved for use in America was in 1996. Since then, many different types of laser and Intense Pulsed Light (IPL) machines or Light Heat Energy (LHE) devices have been developed and improved to remove hair in all areas of the body.

Lasers

A laser is a high-energy beam of light that can transfer its energy through the skin to a specific part of the body. In the case of hair removal, pigment contained in the hair shaft can be targeted by the laser as can the hair follicle or root with a single specific wavelength (or colour) of light generated by the laser. This energy heats up the base of the hair follicle, which causes damage to the cells that produce hair growth; with enough damage this will prevent the hair from growing any further.

Intense Pulsed Light (IPL)

Intense Pulsed Light systems are different from lasers in that they can deliver hundreds of wavelengths (or colours) in each burst of light. Certain filters are used that target these flashes of light so that they can work in as precise a way as lasers. The burst of light to the hair causes damage to the follicle in the same way as a laser.

Light, Heat Energy (LHE)

LHE is a variation on the above, this time delivering both controlled levels of low level light and heat that can be used for hair removal.

Several treatments are required at the start of hair removal treatment because of the natural growth cycle of hair. This is because each hair follicle goes through growing and resting phases, and the hair follicle is most successfully treated by light early in the growing phase.

During the treatment a small hand piece will be used to touch your skin with flashes of light; a cooling spray or gel may also be applied. Most people describe the procedure as a little uncomfortable, with a tingling or stinging sensation during treatment. The procedure can take anywhere from 10 minutes to an hour, depending on the size of the area being treated, and treatments can be repeated at approximately monthly intervals for between two and seven treatment sessions. Most people find that they can return to work immediately after treatment.
Private costs for hair removal using light can range from around £40 per treatment session for small areas such as the upper lip, bikini line and under arms, to £400 per treatment session for the front and back of the legs. The number of treatment sessions that you require depends on your hair colour and skin type as well as the type of machine used.

For those interested in such a treatment, it is important to note that no manufacturer has been given permission to claim that they can cause ‘permanent hair removal’, as this has not yet been proven. However, they are allowed to claim ‘permanent hair reduction’, as that means that whilst hair may not be removed entirely and forever, it will certainly be removed to a significant degree.

Please note that all clinics offering laser, IPL or LHE treatments should be registered with the Healthcare Commission, as they need to follow certain standards for the safe operation and maintenance of these machines and receive regular inspections to ensure that National Minimum Standards are met.
