ColourPop Tumble 4 Ya Cheek Dew Serum Blush ($7.00 for 0.48 oz.) is a medium-dark pink with muted, warm undertones and a soft sheen. The texture was very emollient and runny, which resulted in a formula that seemed overly fluid and was difficult to apply evenly, keep it in place, and diffuse without everything sliding around during application.
I tried to give it some time to dry down, but it was still very prone to just sliding over my skin without adhering evenly. It was sheer, and I wasn't able to build up coverage because it was more apt to result in patchiness and even sheerer color than higher coverage. It lasted for five hours before fading noticeably.
