Is Picoway a 1 for all solution to improve collagen production, skin texture, skin tightening in addition to tattoo?

My primary doctor has recently introduced me Picoway. I had Deep Ultrasound from him before. He now says that Picoway is the newest technology for skin youth solution. But, Picoway.com said it only for tattoo removal. I am a 52 year old Asian female and do have some light dark spots and uneven skin tone. But, what I interested the most is skin tightening. If Picoway really can tighten skin and take care of the dark spot/uneven skin tone, I definitely will consider to try it out.
