I have sensitive skin and eyes and need a hypoallergenic mascara. I have used Clinique Lash Power for many years and absolutely love it! It stays on all day, without smudging, but can be removed with warm water and a cotton wool pad (if you cry or get caught in the rain, the mascara slides off in little tubes but without running or smudging). I can use one application for daytime or layer it up for the evening. Just lovely.
