ColourPop Kiss Kiss is a moderately warm-toned, medium-dark brown with a natural finish. It is a permanent blush that retails for $7.00 and contains 0.48 oz.
ColourPop Kiss Kiss Cheek Dew Serum Blush ($7.00 for 0.48 oz.) is a light-medium brown with warmer, more orange undertones and a soft sheen. It had sheer color payoff in a single layer, which was hard to build up, though it was intended to do so.
The texture was runny, overly emollient and prone to sliding around on my skin, which made it difficult to work with as it did not want to stay in place. So often when I tried to get an even layer and diffused edges, the end result was product that pushed around and left massive patches of bare skin behind (or lifted foundation if applied over complexion products).
I tried an assortment of methods, and for this shade, I had the best luck applying it with a fingertip dabbed onto my cheeks, then letting it dry down a bit before using a stippling brush to diffuse the edge a little bit. I was never fully satisfied with the evenness and blend of the product, though. It lasted for six hours before fading visibly.
