09月16 Is 808nm diode laser and IPL hair removal harmful?
Guide: The light emitted by the laser is a kind of radioactive substance. The laser or photon depilation has radiation, which is harmful to the human body, so it will cause pain during the hair removal process. I believe this is the idea of many people, but is this the case? I will ask the experts to explain them in detail today. Laser hair removal principle and indications
Dr. Zeng Ying from the Laser Department of Sun Yat-sen Memorial Hospital of Sun Yat-Sen University introduced that IPL hair removal and 808nm laser hair removal have the same principle. They are high-energy light emitted by photons or lasers emitted by melanin in hair shafts and hair follicles, which are converted into heat energy and heat energy. Pass along the hair shaft to the hair growth department of the hair – the hair ball. The delicate hair ball in the growing season is damaged by the structure after being heated, and the normal hair can no longer grow, and the purpose of permanent hair removal is achieved.
Dr. Zeng Ying said that the light is the same as the nature of the sunlight or light that we usually touch, but the use of technology to allow IPL or lasers to emit high energy in milliseconds or nanoseconds. Light of a specific wavelength, which is absorbed by the target in an instant, and its energy can destroy the target tissue to achieve the purpose of hair removal or treatment, but does not cause any harm to the human body.
In general, laser or photon hair removal is a very safe method of hair removal. During the treatment, since the melanin of the skin absorbs part of the light energy, it will produce mild pain and discomfort. This reaction is normal.
“If you are too painful, you should inform the doctor in time to avoid skin burns.” Zeng Ying suggested. “Photons that are allergic to light, are taking photosensitizers, and have infections on the skin at the treatment site are also not suitable for IPL hair removal and 808nm laser hair removal.”
808nm Laser hair removal is suitable for all parts of dark and light hair but not for white hair. Extra black hair on all parts of the body (upper and lower limbs, large and small legs, chest, abdomen, hairline, facial beard, bikini line). Electroacupuncture, drugs, electroporation, other instruments are ineffective or failing.
