At the request of The Fashionable Housewife, I put this eyeliner through some extra tests. It might have failed at the pool, but would it last at the gym or simply all day? The short answer, I’m afraid, is no. I went for a run, I cried (not on purpose, it was just good timing!) and I wore it for a normal day. In all cases, my normal eyeliner of choice (Bobbi Brown’s Longwear Gel Eyeliner) fared better. So I guess we’ll have to look elsewhere for eyeliner that truly is waterproof...

I haven’t had the chance to try any of these, but all these eyeliners claim withstand water so they might be worth checking out: Clarins Waterproof Eyeliner Pencil £12.50, Lancome Le Crayon Khol Waterproof Eyeliner £10.50, Max Factor Linemaker Waterproof Eyeliner $4.99, Make Up Forever Waterproof Eyeliner Pencil $18, Smashbox Jet Set Waterproof Eyeliner $22, Dior Waterproof Crayon Eyeliner $23 and finally Bare Escentuals Weather Everything Liner Sealer $23
