Eyes are sensitive, so it's great to choose a paraben free and hypoallergenic eye liner. Try the Autograph Soft Kohl eyeliner at M&S. It's only £6 and comes in four colours, black, brown, charcoal and dark blue. Lots of pencils I've used tend to smudge and disappear - even from top end brands, but this is the best. I use an eye primer and it stays in place all day.
