As the saying goes, everyone has a love for beauty. With the improvement of people’s living standard, more and more female friends start to pay attention to their appearance and skin care. Plastic surgery, injectable beauty and laser beauty are the three popular areas of medical beauty at present. The laser cosmetic surgery is favored by beauty lovers for its efficacy, small trauma, fast recovery and less pain. Today we will talk to the majority of beauty lovers about laser beauty. Laser beauty, as the name implies, is the use of laser for beauty treatment. But not all laser equipment can be used to do beauty, and not all laser beauty equipment can achieve satisfactory results. For example, a long, long time ago, someone used a carbon dioxide laser for skin rejuvenation and it made this look. Of course you don’t have to be afraid, this happened 30 years ago in that flood era of laser aesthetics. Now the pulsed laser cosmetic technology has developed quite mature, safe and reliable. 2018 the inventor of pulsed laser technology also won the Nobel Prize it. Here I will take a look at what mature and reliable laser cosmetic technology is now available. First of all, let’s take a look at the current fire can not be hot picosecond laser. Picosecond laser is an emerging beauty technology in recent years. Many beauty lovers are rushing to hear about the “picosecond laser”. In fact, the picosecond laser is not a cosmetic procedure. It is a technology, or a device. This high quality machine is developed from the Q-modulated laser. It is 10-100 times faster than a regular Q-modulated laser. So just how fast is it? Q-modulated laser is a nanosecond laser, picosecond laser as the name implies is a picosecond laser. Let’s look at the conversion to know how fast picosecond: 1 second = 103 milliseconds = 106 microseconds = 109 nanoseconds = 1012 picoseconds. Picosecond laser is in such a very short period of time to launch a pulse of laser. It is only natural that such a short laser, with a fairly high energy and no damage to the skin, would be sought after by beauty lovers. So, what skin problems can the picosecond laser solve? Is it really a “cure-all” as the legend has it? Let’s take a look at the indications of picosecond laser: 1, nevus of Ota, coffee spot, zygomatic nevus, freckles, age spots and various stubborn pigmented lesions; 2, eyebrow washing, eyeliner washing, lip liner washing, tattoo washing; 3, skin whitening and rejuvenation. It seems that although the picosecond laser cannot cure all diseases, it can solve many major cosmetic problems. In the “red, black, white and tender” four concerns of beauty lovers, picosecond laser except for the “red” (vascular problems) can not help, on other beauty problems have some effect, especially the “fight yellow black “The effect of the laser is remarkable. Finally, a few words about the skin rejuvenation effects of the picosecond laser. The invention of the picosecond laser was initially used to remove intractable tattoos; later was developed by the country to treat a variety of pigmentation, especially yellow chloasma; after several years of clinical practice, we found that picosecond can solve the pigmentation problem, the effect on skin rejuvenation is also very good.
