Although some women are very beautiful, the hair on their faces is very strong, which makes them less beautiful. In order to make their facial skin smooth and flawless, many people choose to do facial laser hair removal. Is facial laser hair removal safe? Let’s introduce it.
Laser is based on the principle of selective photothermal dynamics. By reasonably adjusting the laser wavelength and energy pulse width, the laser dissolving fat can pass through the surface to the root of hair. Hair follicle light energy is absorbed and transformed into heat energy that destroys hair follicle tissue, so as to make hair lose the ability of regeneration without damaging surrounding tissue. Therefore, it is unnecessary to worry too much about the safety of facial laser hair removal, and laser hair removal also has many significant advantages.
The light pulse time is very long. Adjust and protect the epidermis while removing hair of different thickness. Adopt the facial laser hair removal technology. The laser pulse time required for the best hair removal effect is related to the thickness of hair. The thicker the hair, the longer the laser action time required. The laser pulse duration of semiconductor laser is from 5 seconds to 100 milliseconds, which can not only obtain ideal hair removal effect, but also effectively protect the epidermis from thermal damage.
In the past, traditional facial depilation caused pigmentation and inflammation after depilation, especially ruby or emerald laser. This inflammation becomes an obvious and nearly perfect “skin clearing” facial laser hair removal. Due to the deep penetration depth, the epidermis absorbs little laser energy, so there will be no melanin and inflammation.
Sapphire contact cooling patented technology is safe and does not damage. The contact cooling laser head is close to the sapphire window during treatment, so that the local epidermis can be cooled to 5 degrees, which can not only effectively protect the normal from heat damage, reduce pain, but also increase the treatment energy and improve the curative effect. At the same time, the laser head is pressed down to make the hair follicle lodging, which increases the absorption of laser by 30% – 40%.
