@JPMJuliz When I've used it I just have skincare and and a tint underneath.
I know what you mean, it's not the most easily blend-able formula but the colour is gorgeous so worth a bit of extra work. I think good application for me is mostly down to the brush used.
I do one cheek at a time, then press and blend out with quite a dense brush. If it needs a bit more blending I go back in with the beauty blender I used for the tint, if that's diluted the colour a bit too much I go back in with the brush until I get it how I want it.
I've not had any issues with it being patchy during the day. All my tints/foundations tend to be the dewy sort. I don't wear matte bases - could that be an issue?
