The PS01 PST handpiece offers a unique fractional Er:YAG treatment modality. Its innovative optical technology allows the laser fluence of each individual pixel to gradually diminish from the center to the outer edge of each pixel. Transitions from areas of high to low fractional intensity on the skin are therefore soft and gradual, offering a “soft fractional” effect. The PS01 is a variable PST (Pixel Screen Technology) handpiece that allows the number and size of pixels, as well as the overall spot size, to be varied. The handpiece can be set to provide 7, 10 and 12 mm treatment spot sizes. The PS01 fits in Fotona’s Titanium handpieces range, offering maximum durability and minimum weight.
