IPL Technique for Rosacea Redness Using Lumenis One 560 Filter?

Doctor #1 used a small spot size/head for the entire face at 19J. It did not hurt and many pulses were done. Post treatment redness dissipated within the hour. The day after I noticed some subtle improvement in redness. Doctor #2 uses a large spot size with fewer pulses but each was painful! Setting was only 17J. After, my face was red/irritated for 24h. The tech there thought it was odd to use a small head for entire face as it doesn't let enough energy into the skin. Which technique is best?
