Yeah I switched to picosure and it has not had the results like the AlexTrivantage. Then I did research on the picosure and realized it uses a wave length a lot lower than the Q switch lazers. Picosure operates at a 700 wavelength which targets greens and blues it hits black but does not penetrate deep enough to remove black. The Q-switch lazers operate at 1064 and go deep enough to remove black. And you can actually adjust the setting for different colors.
My tattoo has black, green, purple and a pinkish salmon color. The picosure only targeted my green and left the rest of my arm pretty hypopigmentated.
Now I'm going to a different place with a a Q-Max lazer.
