Nanosecond Q-switch Laser Pigmentation Treatment Before and After:





Q-Switched Nd YAG Laser Pigment Removal Tattoo Removal Machine
HF-503Q Nano laser compared to conventional Q-switched laser, it has a pulse width of only 6ns.
The treatment of the skin is mainly mechanical effect, through the principle of the light mechanical shock wave, the pigment crushes fine particles through focused energy, it is more easily metabolized by the body.
The pulse width output of 6ns can reduce the effect of thermal effect. It is also convenient to observe skin reactions during treatment. It is very effective in treating pores
Q-switched laser are ideal for pigment treatment: Broad medical opinion based on long-term clinical research believes that Q switched laser are ideal for pigment removal. Their nanosecond pulses generate megawatt-level power, producing a powerful and controllable photomechanical effect that breaks up pigment particles and destroys the cells they contain; effectively removing pigment.

532nm: used to treat epidermal pigmentation, such as freckles, solar lentigo, epidermal melasma, etc. (mainly for red and brown pigmentation).
1064nm: used to treat tattoo removal, dermal pigmentation, and treatment of certain pigmentation conditions, such as Ota nevus and Hori nevus. (mainly for black and blue pigmentation).


Q-switched laser uses Q-switched technology, which is an effective method to obtain high-energy short pulses.
The principle of treatment is to use selective photothermal effect to emit high energy in a very short time, targeting and “breaking” the pigment clumps in the skin, turning the pigment clumps into tiny pigment particles, which are then metabolized by the body.
Picosecond laser was first developed for better tattoo removal, and its indications have gradually expanded to various pigment spots. Picosecond (ps) and nanosecond (ns) refer to pulse width, i.e. pulse duration.
For currently available devices, the pulse width of pico laser is more than 10 times shorter than that of nanosecond Q-switch laser devices.
