Congratulations on starting this. It was a big moment for me as it marked the first, irreversible step.
I pop some over the counter type pain killers beforehand- seems to take a little of the sting off.
Remember to keep out of the sun.
oh and move your tweezers out of easy reach from the sink... when distracted or tired you may forget and pluck somthing- which means the laser will miss it next time!
Plenty of cooling creme, I also love a bag of frozen peas.
I wish you luck and a fast clearing!
