Laser hair removal is a cosmetic procedure that uses a laser to remove unwanted hair on the body. The laser sends light energy down to the hair follicle and that energy damages the follicle and prevents it from growing new hair. Laser hair removal is most effective for people with light skin and dark hair. It can be used on any part of the body, including the face, legs, arms, and underarms. Laser hair removal is a popular method for removing unwanted hair, but how does it work? In this article, we explore the science behind laser hair removal, the price, and what you need to do to prepare for your session. Keep reading to find out more.

How does the laser machine targets and destroy hair cells?

When the laser machine targets and destroys hair cells, it emits a beam of light that is absorbed by melanin, which is the pigment in the hair. The laser energy is converted to heat, which damages the hair follicle and prevents new hairs from growing.

The mechanism by which laser hair removal machines destroy hair cells is not fully understood. However, it is thought that the light energy emitted by the laser is absorbed by the melanin in the hair follicles. This absorption causes the hair follicles to heat up and destroy the hair cells.

How much is laser hair removal?


Laser hair removal prices vary depending on the clinic, the location, and the size of the area being treated. Typically, the cost ranges from $5ths 8 to $600 per session. For example, Bellissima offers affordable laser hair removal costs for certain body areas starting at $58 a month that include underarms, jawline, bikini, lip, chin, sideburns, hands, feet, ear, stomach line, inner cleavage, areola, nose, and cheeks.

Larger areas of the body like Brazilian, full neck, upper back, lower back, lower legs, upper legs, abdomen, chest, and full arms can start from $128 per month.

How do I prepare for my first laser treatment?


The first step in preparing for laser hair removal is to figure out how much hair you want to remove. You’ll need to determine the size of the treatment area and then calculate the number of treatments needed.

Once you know what you’re working with, schedule a consultation with a laser technician who can help you choose the best type of laser for your skin type and hair color. They will also give you specific instructions on how to prepare for your first treatment.

Generally, patients are asked not to wax or pluck their hair for at least four weeks before their appointment. Sun exposure should also be avoided in the days leading up to the treatment. The technician may recommend using a topical numbing cream if you have a low pain tolerance.

On the day of your appointment, arrive freshly bathed with completely clean skin—that means no oils, lotions, or makeup. You may be asked to shave the treatment area beforehand so that the technician can get an accurate reading of your skin tone and hair color.

Once you’re ready for treatment, the technician will place a cold gel pad on your skin and use a hand-held device to deliver short pulses of light energy directly into your follicles. Most patients feel only minor discomfort during this process—like a rubber band snapping against the skin but you can apply a numbing cream to the area before your treatment. Most people require six to eight treatments spaced four to six weeks apart in order to achieve optimal results

Altogether, laser hair removal is a highly effective way to remove unwanted hair. It is a minimally invasive procedure with few side effects, and the results are long-lasting. Overall, laser hair removal is a safe and effective way to achieve hair-free skin.
