Yeah, it's perfect.
You need the tiniest dot and it glides on silky smooth, blending super easily...not putty or cakey like at all.
Of course, I use this over MAC prep and prime eye b/c I like that MAC's formula is somewhat moisturizing...but MAC p&p can't hold shadow and liners without creasing or fading like UDPP does. I use the MAC mainly just b/c I already owned it and it holds my mineral foundation on my undereye area so well that i don't need to use concealer, and helps my UDPP spread even easier.
I've (unfortunately) passed out with my makeup on several times since starting to use this technique and my eye makeup still looks wonderful. Perhaps a little faded, but not too much, and definitely still good and wearable. It probably wouldn't fade if I didn't use the mac p&p under it or toss and turn so much...but I don't like my primer to hold on TOO tightly to pigments, since I like to do my make up as quickly as possible and hate struggling to blend.
