I recently switched from using Bobbi Brown's gel eyeliner to using an eyeliner pencil as it goes on smoothly and is much quicker than faffing with a brush...but in the warm weather it seems to smudge really badly and end up in dark circles under my eyes. So I bought a waterproof one, which just seems to mean that the smudgy circles are slightly smaller. Can anyone recommend a non-smudgy non-running eyeliner pencil?
