Laser hair removal or photothermolysis is a hair removal technique that utilizes light energy to destroy the pigment and hair follicle cells, which causes them to shrink and fall out. This procedure is usually performed by a licensed dermatologist on patients who have darker skin tone and a darker underarm area.
In a photothermolysis procedure, a very deep penetrating beam of light is used to destroy the pigment in the hair follicles. The body regenerates the hair follicle cells as it shrinks. In some cases, the amount of hair removed is not as great as the full growth of hair in the affected area.
In some cases, patients may experience moderate to mild irritation at the site of treatment, but this does not last for more than a few days after multiple laser treatments. Some side effects may include moderate stinging, slight redness, burning, or itching around the treated area for a few days. These side effects usually subside within a few weeks and may only be temporary. Лазерная эпиляция груди
There are no common problems with using laser hair removal on people of any race. However, women are more likely to experience scarring at the treated area, which can occur if more than one treatment is performed on the same site. After each treatment, a small scar may appear.
Light treated areas that are in shadow often receive more light. The darker the skin tone of the area, the less light reaches it. Skin darker in color usually receives less of the light treatment. Thus, patients with darker skin may receive less of the light treatment as compared to people with light skin tone.
Sun exposure increases the body’s immunity against infections and other diseases. Sun exposure also protects the skin from the sun’s ultraviolet radiation. In particular, the upper dermal layers get damaged easily by exposure to ultraviolet radiation from the sun.
People who go outdoors on a moderate level of sun exposure or participate in physical sports should consult their dermatologist before undergoing laser hair removal. The typical treatments that are given include the sine-wave laser, single pulse, and the pulsed-pulse laser.
Low doses of light are usually administered because the skin is less sensitive than other parts of the body. The skin reaction to light is much less than what is seen with traditional medications and medicines. Most of the treatments that are done in medical facilities involve the sine wave laser, which is considered to be the most effective among all the lasers available.
