Buy leather cleaner.
I have leather couches in my home, and I urge you NOT to use hairspray (as the alcohol in hairspray may discolor the leather.)
Suggestion by ideally_rational
Nellbelle is right.
Whatever you use, test a small corner of the back of the couch first to see if it stains or bleeds the color from the leather.
I have an ink and lipstick remover kit that came with my couch. I’m sure you can find some on ebay.
