Developed in the 60s, laser treatments that were once used for hair removal only have become increasingly successful in recent years and can now treat everything from excess hair growth to pigmentation. A number of laser treatments are now available, using highly concentrated frequencies of light to treat a variety of skin complaints.
How it all works
Each laser treatment is based upon the skin, or cells within the skin, absorbing the energy from the laser, which then causes damage to those cells. Because the cells are damaged they need to regenerate, which is why lasers are often used to treat scarring and stretchmarks – damaged skin cells are replaced by new, fresh skin cells, improving the overall tone and texture of skin.
Laser hair removal is very effective and works in a similar way. The pigment in the hair follicle absorbs the energy from the laser. This energy damages the hair follicle, and over time, with repeated treatments, the hair follicle stops producing more hairs. Laser hair removal usually works best on pale skin with darker hairs, as the dark pigment in the hairs absorbs the laser light while the pale skin reflects it. Repeated treatments are needed because hair grows in cycles and needs to be treated at the right point in its cycle. Hair follicles are damaged and as they stop producing hairs, skin becomes smoother and softer.
Laser treatments work so well because the wavelengths of light are absorbed only by very specific skin cells. In hair removal, for example, the energy from the laser is absorbed only by the hair follicle, which means that the hair follicle is damaged without any further damage to the surrounding cells. Laser treatments generally cause very few side effects, as the surrounding tissues are not affected by the laser in any way.
What you need to know about getting laser hair removal
Laser treatments require an incredibly high level of expertise and precision, to ensure that the laser is targeted towards the desired treatment area. Clinics with highly trained doctors, nurses and clinicians can generally provide patients with the most effective treatments and this is due to the medical approach that these clinics use. Laser treatments can provide permanent results and can also cause severe side effects if not administered correctly, which is why it is highly advised that you visit a reputable clinic for your treatment.
Laser hair removal can be slightly painful. Most patients would describe the sensation as a “sting”, similar to the feel of an elastic band being “pinged” against skin. Generally, anaesthesia is not required and most people tolerate the treatment extremely well.
