Clinique Touch Base for Eyes is the only eye shadow primer/base that stays on all day and prevents creasing. It is very pretty when used on its own. I have tried Urban Decay, Mac paint pots, Paladio, etc., etc. Other products do not hold up like it.
This is the best eye shadow base EVER! I sometimes wear it alone, but mostly under eye shadow. Holds the color all day, too! I like it because it has no sparkles so it doesn't accentuate wrinkles. I would highly recommend this!
