What is the difference between picosecond and super picosecond？

The principle is different：

Picosecond laser refers to the use of photothermal principle, using a 755 wavelength laser and a honeycomb instant lens Focus Lens Array to focus 70% of the laser energy into the deep layer of the skin, locate the melanin, and instantly shatter the melanin.

The principle is different：

After smashing the melanocytes with high power, it stimulates the collagen fiber network to start the skin repair function, promotes the renewal and proliferation of collagen and elastic fibers, accelerates the metabolism of the skin, accelerates the metabolism of melanin and excretes it, and has an additional effect of beautifying the skin.

Ultra-picosecond uses physical effects, so there is no photothermal effect.

Super picosecond uses Resolve holographic pixel technology to provide a focused micro-beam with a 6mmx6mm spot size and a 10x10 array. Resolve holographic lattice focusing technology itself contains two black technologies, one is the holographic diffusion effect, and the other is double-layer focusing. Holographic diffusion is to turn a single beam into a beam group, which is extremely fine and equal in energy; double-layer focusing means that the two wavelengths of 1064nm and 532nm can solve the pigment in the epidermis and dermis. Pigmentation has nowhere to hide.

The principle difference between picosecond and super picosecond lies in the probe technology.

The photothermal effect used by picoseconds, the light shock speed is 7 times that of traditional lasers, so a few people feel slight discomfort during the treatment process, and some people have redness after the operation. The super-picosecond focused micro-beam has an optical shock speed 11 times that of traditional lasers. Even if the skin does not feel pain, the melanin has been crushed. Therefore, in terms of skin damage, the rate of darkening and pain are greatly reduced when the damage is small. In this regard, super picoseconds are better than picoseconds. Moreover, the holographic lens can make the energy distribution of the beam more uniform, and the effect on the skin is more delicate and uniform. Compared with the picosecond, the use of the super picosecond is better.

Different in nature：

Super picosecond has three wavelengths of 1064nm/532nm/785nm, which can reach a depth of 3-4mm under the skin, but more conservatively, super picosecond uses traditional Nd:YAG lasers, which were born in grass roots. Different spot species have different pertinence to laser light, and different target tissues have their own unique absorption wavelengths for light. Therefore, according to the color of the target tissue, choose the laser with the corresponding wavelength (532nm, 785nm, 1064nm). That is to say, the more types of laser wavelengths and the finer the distinction, the greater the range of spots that can be improved.

The lower the number, the shallower the depth, and the closer to the epidermis, the stronger the intensity.

The larger the number, the deeper the depth, the closer to the deep layer of the dermis, the weaker the intensity.Double-layer focusing means that the two wavelengths of 1064nm and 532nm can target the pigments in the superficial epidermis and deep dermis. There are corresponding wavelengths for the inside and outside to deal with it. The accuracy is wider and the coverage is wider. Live control to a minimum.

Different pulse width：

In laser, the improvement of effect and safety is mainly in the pulse width, while the comprehensiveness is mainly in the wavelength.

The pulse width refers to the speed of the laser. The shorter the pulse width, the faster the laser speed and the greater the energy focus. More importantly, the shorter the time, the less damage to the skin.

The pulse width of the laser is defined as super picosecond at 1ps-400ps, picosecond at 400ps-700ps, and sub-picosecond at 700ps-1000ps.

The pulse width of a picosecond is 750ps, which can be compressed to 550ps by boost technology. Some people say that a picosecond cannot be regarded as a real picosecond, but can only be called a sub-picosecond.

Picosecond compresses the ultra-short pulse width and generates a strong photomechanical effect with less energy, which can break the pigment tissue and particles into tiny particles, so that they can be metabolized by phagocytic cells.

And the shortest pulse width of ultra-picosecond reaches 375ps, which can be regarded as a real ultra-picosecond;

With strong energy, there is more guarantee of safety, so less damage to the skin is the advantage of super picosecond ultra.
