Experts tell you whether laser beauty is really that safe.

In recent years, more and more female friends will choose laser beauty, saying that laser beauty has brought them the right to enjoy beauty. Why is laser beauty so hot? Is laser beauty safe? With such questions, let's see what the experts say.

Laser cosmetic treatment is safer because it uses laser beam instead of radiation. And the laser enters the skin with only slight pain, just like the feeling of being bounced by a rubber band. However, no matter how safe it is, patients must wear goggles to protect their eyes during the treatment, and when the operation is close to their eyes, they should also wear goggles to protect their eyes after dropping eye drops.

The monochromaticity of laser makes the wavelength of laser match the absorption spectrum of pigment and photosensitive material accurately. Good directivity can concentrate high-intensity laser energy in optical fiber for transmission. High-energy pulsed laser can cause local thermal damage in the spot area, but heat conduction has little damage to the surrounding tissues. Laser with different wavelengths will be absorbed by special colors or pigments in the skin, and melanin is the main substance that absorbs laser. Blood vessels in the skin can absorb light of multiple wavelengths.

Freckles easily absorb green light; Hemangiomas easily absorb yellow light; The absorbed laser produces a thermal effect with tissues, especially pigments, thus evaporating light energy or smashing "targets" to achieve the purpose of treatment. The thermal effect produced by laser can be used to treat skin vascular diseases, pigmented spots and tattoos.

Of course, no treatment is perfect, and laser beauty has its limitations. Laser cosmetology is a new technology, which has not developed for a long time, and some problems remain to be solved. In addition, friends need to pay attention to the fact that laser treatment cannot achieve perfect results at one time and needs to be carried out many times. I hope everyone will treat it calmly and rationally.
