HELP! Permanent Marker on Leather Couch

My kids had Sharpie marked a friend on a sleep over and it had gone onto my 15 month old ivory leather settee. I looked through this website and spray sunsceen seemed most popular to remove the stain. I tried Banana Boat spray factor 50 and it came off straight away. It really works. What a relief:) You have to use a spray (I tried a cream first and it didn't do much).
