The differences are as follows:

First of all, the properties of lasers are different.

1, pico-path: three-wavelength (532 nm/785 nm/1064 nm) Nd: YAG laser;

2.PicoSure: Emerald 755 nm laser. ?

Second, the laser pulse width is different.

1, picosecond: the shortest pulse width reaches 300ps, which is a real picosecond.

2. PicoSure: the pulse width is 750ps, which can be compressed to 550ps by boost technology. Not a real picosecond, just a picosecond.

Third, the principle of action is different.

1, picosecond: Different target tissues have their own absorption wavelengths for light, so according to the color of the target tissues, the laser with corresponding wavelengths (532nm, 785nm, 1064nm) is selected, and picosecond pulse energy is generated by picosecond technology and transmitted to subcutaneous tissues. These bursts of energy form a photo-mechanical impact, which breaks down the melanin under the skin into tiny ones.

2.PicoSure: By compressing the ultra-short pulse width, a strong photo-mechanical effect is generated with less energy, which can break pigment tissues and particles into tiny particles, which is beneficial to the metabolism of phagocytes. ?

Fourth, the core technologies are different.

1, PicoWay: The unique Resolve holographic pixel technology aims to provide a 10x 10 array focusing microbeam with a spot size of 6mmx6mm and a manual wavelength of 532nm and 1064nm. Resolve uses holographic diffraction beam splitter technology to manufacture array beams, but compared with diffractive microlens technology, holographic technology is more expensive and more technical.

2.PicoSure:focuslensrarray honeycomb lens technology, which further focuses the laser energy locally, so that the laser energy can be transmitted to the deeper dermis without destroying the epidermal skin barrier, which can attack deeper spots, improve pigments and stimulate collagen proliferation.

5. Different qualifications.

1, picoway: EU CE, US FDA.

2014165438+13 October, PicoWay was approved by FDA for tattoo removal, and on 20120 April, it was approved for pigment diseases.

2.PicoSure: FDA of the United States and CFDA of China.

201212 On February 4th, PicoSure was approved by FDA to remove tattoos and benign pigmented lesions. 20 14 On September 24th, PicoSure's FocusLensArray handle was approved by FDA for wrinkle removal, skin rejuvenation and treatment of acne atrophic scar. On September 2nd, 20 15, PicoSure was officially approved by CFDA (China Food and Drug Administration) for tattoo removal treatment, which means that the first picosecond laser equipment entered the domestic market. ?

Extended data

Laser beauty:

First, lasers are used more and more widely in the beauty industry.

1, pigmentation, such as nevus OTA, nevus flammeus, freckles, senile plaque, telangiectasia, tattoo removal, eyeliner washing, eyebrow washing, scar treatment, etc.

Before 2.20 13, some new laser instruments, such as high-energy ultra-pulse CO2 laser and erbium laser, were used for wrinkle removal, skin peeling and skin changing, snoring treatment, tooth whitening, etc., and achieved good results, which opened up more and more broad fields for laser surgery.

Second, laser surgery has incomparable advantages over traditional surgery.

1. First of all, laser surgery does not require hospitalization, with small incision, no bleeding during operation, light trauma and no scars.

2. For example, the traditional surgical treatment of bags under the eyes has many shortcomings, such as wide peeling range, more bleeding during operation, slow postoperative healing and easy scarring. The application of high-energy ultra-pulse CO2 laser in the treatment of eye bags has the advantages of no bleeding, no suture, no influence on normal work, light edema at the surgical site, quick recovery and no scar left, which is incomparable to traditional surgery.

3. Some endoscopic operations that cannot be performed due to excessive bleeding can be completed by laser cutting instead (note: there is a certain scope of application).

Thirdly, laser has achieved remarkable results in the treatment of vascular dermatosis and pigmentation.

1. Pulsed dye laser is effective in the treatment of port wine stains, with little damage to surrounding tissues and almost no scars. Its appearance has become a revolution in the history of treatment of port wine stains, because in the history of treatment of port wine stains, radiation, freezing, electrocautery, surgery and other methods have a high incidence of scars, and pigment loss or deposition often occurs.

2. Laser treatment of vascular dermatosis is the selective absorption of oxygen-containing hemoglobin to a certain wavelength of laser, which leads to the high destruction of vascular tissue. It has high accuracy and safety, and will not affect the surrounding adjacent organizations. Therefore, laser treatment of telangiectasia is also effective.
