It’s a never-ending effort to keep body hair at bay. From the simple razor to waxing and permanent treatments, there are a variety of hair removal techniques available. Lasers are a highly effective long-term treatment for maintaining smooth, hair-free skin. It’s a straightforward approach of permanent hair removal with few drawbacks.

How does it work?
Laser hair removal works by zapping the hair follicle, effectively eliminating the hair’s root. No hair can develop from a follicle that has been killed. Each follicle is targeted with a powerful laser beam that penetrates deep into the skin to reach the soft tissue beneath.
When the laser’s heat reaches the follicle, it effectively stops the follicle from producing hair. Given the vast number of hairs on the body and the fact that each one must be treated separately, the procedure may take some time, and depending on the area of the body being treated, many sessions may be required to eliminate all hair follicles. On light skin with thick, dark hair, laser therapy is most effective.
To completely eliminate all unwanted hair, numerous laser therapy sessions may be required. The laser may just harm the follicle rather than entirely destroy it. When this happens, the follicle can heal (though it may take a long time), allowing the hair to regrow. After then, the treatment will have to be repeated. Although adverse effects from treatment are uncommon, some persons with sensitive skin may feel discomfort. Some people may experience side effects such as skin blistering, darkening or lightening of the skin, and other mild irritations after a laser treatment. If appropriately managed, most issues will go away in a few days.
Hair removal is more difficult on darker and tanned skins. This is due to the fact that darker skin absorbs more heat from the laser than lighter skin. As a result, the follicle receives less heat than is required to completely kill it. Experts advise against tanning before to laser treatments. Laser hair removal procedures may require more sessions for those with darker pigmented skin to get rid of unwanted hair.
A cooling gel is given to the skin during laser treatment to lessen the effect of the heat and minimise any side effects.
Lasers of various types
Hair removal uses a variety of lasers with different wavelengths. The heat that destroys the follicles is converted from the laser’s light energy. It’s a very specific therapy that’s focused on the follicle’s particular location. The follicle is destroyed in two ways: by heat absorption by the melanin pigment in the hair and by penetration deep into the epidermis.
Lasers target the hair shaft and follicle specifically while avoiding the surrounding skin, limiting the amount of damage to the region required to remove the hair. Short pulses are also utilised to raise the temperature of the melanin in the hair shaft and follicle.
