Benefits of laser hair removal include:
Precision. Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.

Speed. Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, may take up to an hour.
Predictability. Most patients have permanent hair loss after an average of three to seven sessions.
Laser Hair Removal Side Effects
While the procedure involved in the laser treatment is usually risk-free, there might be some side effects of laser hair removal to consider.
The use of a laser to remove unwanted hair involves a lot of heat to burn the hair. This can lead to skin burns in some users. The laser hair removal burns occur more frequently in patients with darker skin, as skin with darker pigments absorbs the laser more readily. While, in most instances, the burns are mild, there have been a number of cases where severe burns have been reported.
The laser may cause hyperpigmentation and hypopigmentation.
a. Hyperpigmentation is the darkening of the skin that may occur after the laser hair removal. The laser treatment stimulates melanin production creating a reaction similar to suntan.
b. Hypopigmentation, on the other hand, refers to the lightening of skin that occurs after the laser treatment. The absorption of laser light can inhibit the melanin production, leading to a loss of pigment.
It might also lead to eye injuries, so it is important to protect your eyes during the process of laser treatment.
Itching is a normal side effect of laser hair removal during and after the treatment.
The skin turns red for a few days following the treatment, and there is likely to be swelling around the follicle after the treatment.
Pain, tingling, and numbness around the treated area by the laser are probably the most common side effects that can be considered normal.
Laser treatment can lead to crusting and formation of scab around the area treated. A mild bruising may also occur on sensitive skin. These side effects appear within the first few days of the treatment and disappears shortly afterward.
A very rare side effect of laser treatment is purple coloring of the skin on tanned areas.
Another rare but significant side effect of laser hair removal is infection. It is important to keep the area clean after the procedure, or you could end up getting an infection after the treatment.
