What is a picosecond laser?
Different objects absorb and reflect light at different wavelengths in different ways -- the tattoo ink works the same way. For example, red tattoos absorb all colors of visible light except red. Tattoos look red to our eyes because they reflect red instead of other colors. So if your goal is to crush the ink in a red tattoo, you don't want to treat it with red light because it will reflect all light without absorbing energy. The 1064 nm wavelength is ideal for removing dark or dark streaks because light energy at this wavelength is well absorbed by black ink. Since the ink color most commonly used by tattoo artists is black, 1064 nm is the most commonly used green laser pointer wavelength for tattoo removal. As a result of laser hairdressing is based on selective photothermal action to achieve the purpose of treatment: only on the target tissue (melanin) effect, and other intact skin tissue does not produce obvious damage.

Generally used to remove spots, remove birthmarks, remove tattoos, acne marks is q-switch laser, its pulse width is nanosecond level, and the picosecond laser speed is far more than the traditional Q-switch laser. Picosecond laser is a picosecond pulse width laser. With the characteristics of picosecond ultra-short pulse width, adjustable repetition frequency and high pulse energy, it has been widely used in biomedical, optical parametric oscillation, biological microscopic imaging and other fields, and has gradually become an increasingly important tool in modern biological imaging and analysis system. Laser cosmetology has become a hot means of medical beauty in these two years. Picosecond high powered laser is a kind of laser beauty. The picosecond refers to the time scale. That is, the duration of each laser pulse can be accurate to the picosecond scale. Picosecond lasers typically take at least a week to show results, because the skin needs a basic repair cycle. Instead of seeing a dramatic effect, many beauty-lovers feel sesame-shaped black spots on their faces. Postoperative pigmentation is the melanosis after superficial wound healing, mainly caused by the stimulation of melanocytes in the skin, which is more common in the exposed site. In fact, melanocytes change during repair, and ACMETEA can promote the repair of pigment cells, which has a certain role in promoting recovery. It can repair melanocytes in time and restore the skin to normal color. Meanwhile, the carotene contained in ACMETEA can maintain the normal function of skin cells and immune system.
