Should a correct application of Levulan result in a more uniform redness to the face?

2 days ago I had levulon with phototherapy. During the application I noticed and mentioned that I was afraid the levulon was not applied uniformly. Now I have well demarcated “stripelike” areasof redness. And one side is barely pink while the other is “more red”. I love the plastic surgeon and the staff are very nice. But I’ve had some minor issues such as being accidently over charged, scheduled for a wrong procedure and no prior phone call to change the appointment. They seem sloppy
