how to blur parts of my film

hi there,

i try to color grade my film using color, and i am loving it!!

anyway, thats not the issue here...

i was wondering how i can blur a certain area of my footage. there are some areas on the skin

that have to "disapear" or just should look more smooth than they do.

i thought i can use a vignette, track it an than blur it a bit. but there does not seem to be a blur

funktion for that!?

or is there another way of smoothing that area?

please don't say: use the colorFX room, as i find it very complicated to use...

thanks for your help.
