1.Is it only caused by uva /uva?And if i would stay out of the sun,inside the house with dark curtains closed for 6 months,will there be a chance of getting hyperpigmentation,when i will sunbath a little again? 2.Or is the hyperpigmentation maybe also caused by sun damaged skin laying under the surface,which will come towards the surface because of the Active FX,and will (even after I stay 6 months out of the sun) more easily become hyper pigmented when my skin will be exposed to the sun again?

Answer: Hyperpigmentation causes after Active FX
Hyperpigmentation occurs from stimulation of the pigment producing cells (melanocytes) and many things can do this. UV light is one thing, but even without light, pigmentation can occur. Inflammation stimulates the cells, so the heat from the laser treatment can stimulate these cells and if your skin type is darker this is more likely to happen, think the dark mark after a burn or even the dark mark that occurs after a pimple. The good news is once the inflammation resolves, usually 4 to 6 weeks, your skin will not hyperpigment because nothing is there to overstimulate the cells. Prepping the skin before the treatment quiets the cells and lessens the chances for pigment production during the inflammatory healing period, as does treatment after the laser with soothing and calming lotions and even sometimes steroids to decrease the redness.
The second part of your question does not cause hyperpigmentation. And as always, remember sun protection to protect your skin and your investment!
