Laser hair removal is a treatment that utilizes light energy of specific wavelengths to selectively destroy hair follicles, commonly used to reduce or eliminate unwanted body hair. Laser hair removal devices emit light energy, not radiation. This light energy is absorbed by the melanin in the hair follicles, generating heat that damages the follicles, thereby achieving hair removal. The emission range is typically within one meter, and both the power and energy density are within the safety limits defined by national and international standards.
The light energy used in laser hair removal is not the type of radiation commonly misunderstood by the public, so radiation risks are not a concern. To ensure safety and effectiveness, it is recommended to undergo laser hair removal at qualified medical facilities operated by experienced professionals. Prior to treatment, the physician will assess the patient's skin type and hair color to determine the most suitable laser parameters.
Before using a laser hair removal device, it is advisable to perform a skin test to ensure there is no allergic reaction. Additionally, proper post-treatment skin care is necessary to prevent infection. For pregnant women or individuals in special physiological conditions, laser hair removal should be performed under the guidance of a physician.
