Lesions
Melanin generated in the melanocytes is an important factor that determines the skin color of the human.
It plays a role in protecting the skin against UV rays. If melanin cell is exposed to strong
UV rays for a long time,
more melanin is generated to protect skins. If excessive melanin pigmentation is accumulated, pigmented lesion
such as freckle, melasma, blemish and so on is caused.
Pigmented lesions can occur through a variety of causes
such as aging, heredity, hormones, stress, temperature changes, lack of sleep, as well as the UV rays.
IRIS uses a Long Pulse Duration, while the Photothermal Reaction eliminates denatured pigment.
The high rate at which melanin absorbs 532nm wavelengths is effective for treating pigmented lesions
such as freckles, age spots and liver spots. The melanin in the pigmented lesion absorbs thermal energy
from the laser and becomes denatured after a certain period of time, leading to visible skin improvements.
Spots and pigmented lesions such as lentigo can be removed by using the Normal Mode(Surgical mode).
Fractional Mode irradiates micro laser beams to the skin, which makes the skin tone brighter.
