Upper lip = move your kisser down a 1/16" at a time and try a shot.

Mine did that back in 1996. I was comfortable with the anchor, nose on the string and peep height. My upper lip was taking a pounding. I moved mykisser down 1/16", retied and shot...repeated over and over again until I found a comfortable place for my kisser while still keeping my nose on the string and anchor.

You might also want to make sure that there are no burs on the kisser and if all else fails, look for a smaller kisser or remove it.
