Personally, I love the product. I bought three when ELF had that 75% off their studioline. I give it five stars because it was dirt cheap, the packaging is sturdy and beautiful, and it does a wonderful job evening out my skin and creating a great canvas for blush and contouring. I never tried it on my bare skin but I use it after I apply my foundation. I just use the complexion brush and sweep it over all four colors and lightly apply it on my face. I can see a difference. My face is just one color so it's perfect for putting color on my face. I don't really like using the colors individually, it makes only a slight difference but then again I don't really need spot treatment so maybe that's why I can't tell the difference?
