E.L.F. Essential Blushers usually half the size of E.L.F. Studio Blusher. Flushed is a beautiful Barbie pink shade with very fine shimmer that it is almost matte. Mellow Mauve on the other hand is mauve-y shade with purple shimmer, it's like the big sister or maybe mom to Flushed. These two hardly a dupe to each other.
Pigmentation wise, both blushers are moderately pigmented. I prefer my blusher to be moderately pigmented so that it's easy to work with and still show up on my skin. I rather take some time building up color than end up having to remove everything because one swipe is too much.
