The four main reasons for the formation of facial spots are as follows:
(1) Genetic reasons. Autosomal inheritance is the main cause of facial pigmentation. It usually starts in children around 5 years old, mostly in women, and is more severe in spring and summer and less severe in autumn and winter. Light brown to yellowish-brown pintip to rice grain-sized spots, symmetrically distributed on the face (especially the nose).
(2) Ultraviolet irradiation. Ultraviolet radiation in the sun is an important cause of the formation of facial spots, which is why sun protection is needed in summer. When the skin receives too much sunlight, the epidermis produces more melanin particles, which absorb ultraviolet rays and protect the body from damage. This is why everyone’s skin will turn darker after being exposed to the sun. Moreover, ultraviolet rays can cause chloasma and deepen the color of common facial spots.
(3) Endocrine reasons. Endocrine disorders are also an important reason for facial pigmentation in women. Changes in sex hormone levels during menstruation and pregnancy can affect the production of melanin. In addition, endocrine instability often causes emotional instability and can also indirectly cause the formation of facial spots
(4) Lifestyle issues. Bad lifestyle habits such as stress, partial eclipse, and lack of sleep can also increase melanin. People with unstable sleep schedules also have poor skin metabolism, which will affect the production of melanin particles.
Picosecond freckle removal principle:
PicoWay is a new laser instrument from the United States. Picosecond laser is the time that light hits the skin and stays on the skin - picosecond level. The unique feature of this device is that it instantly delivers ultra-short pulses to the target tissue, shattering the target pigment clumps into fine particles through photoacoustic action, and metabolizing them out of the body more safely and effectively. At the same time, through innovative 3 wavelengths, holographic diffraction lens lattice mode and other outstanding technologies, picosecond laser has been brought into the "picosecond laser 2.0 era".
