My tattoo barely looks any different a week after my first Picosure treatment. Is this normal? (Photo)

Its now been a week and there is barely any difference. I did a patch test an hour before and it seems to be the only part of the tattoo actually doing something. The tattoo is 5 months old, it has browns, pink, blue, green and purples. I know that there is a small chance that the pink will fade completely but the rest almost looks the same. The flower on the top right was not lasered but everything else is. The only part that got small boils and scabs is the test patch. Is this normal? Tania
