Скачать или смотреть How Laser Hair Removal works? Is it Safe?

Laser hair removal is a cosmetic procedure that uses laser technology to remove unwanted hair from various body parts. This procedure can nearly permanently reduce hair growth, making it a popular choice globally.

Let’s see how this procedure is performed:

Preparation: Before the procedure, the hair in the treatment area is trimmed short. Then, a cooling gel is applied to the skin to protect it from heat damage during the process.

Laser Application: The laser's intensity is adjusted based on the color of the hair. A dermatologist uses a handpiece to direct controlled laser beams at the hair, which destroys the hair through heat.

The Science Behind the Procedure:

Melanin’s Role: Hair contains a pigment called melanin, which gives it its dark color. Melanin is also present in the skin, but in smaller amounts compared to hair, which makes skin lighter in color.

Laser Interaction: The primary function of melanin is to protect the skin from high-intensity wavelengths of sunlight by absorbing light. During laser hair removal, the same melanin in hair absorbs the laser light. Because the laser’s light intensity is very high, the absorbed light heats the hair, and this heat travels down to the hair bulb.

Hair Follicle Damage: The hair bulb, a part of the hair follicle where hair production occurs, contains melanin and hair-producing cells. When these cells absorb the laser light's heat, they get damaged.

Stopping Hair Growth: Once the hair-producing cells are damaged, they can no longer produce hair. Since a single laser session may not destroy all hair follicles, multiple sessions are often required for the best results.

Safety Considerations:

Though the procedure might seem harmful to the skin, it is generally quite safe. It's essential to ensure your dermatologist is well-experienced because adjusting the light intensity properly for each individual's skin and hair is crucial to avoid skin damage along with hair removal.
