Does anyone have any opinions or suggestions regarding an undereye concealer that they use that doesn't blend into the crease of the delicate undereye area?

I have used cheap products right through expensive cosmetics. Recently purchased all the "tricks" from Bobbie Brown spent a fortune for a makeover. After several hours after application, (I work 12-14 hour shifts), I find my dark shadows/circles covered fairly well, not great, but any little creases are more accentuated due to concealer settling. Any suggestions I'd appreciate them. Also any good creams to use for the eye area prior to application of the concealer and a wrinkle cream for forehead horizontals lines would also be great.

Thanks Marilyn
