ColourStay liquid foundation for oily/combo skin is my holy grail so I was keen to try this ColourStay. The texture is more moussey, similar to the old "Whipped" version that came in a screwtop jar. Being a moussey texture it is easier to apply with a brush, a sponge is harder to blend but if you are like me and prefer a sponge I would spread the foundation over the face and then quickly dab and blend out. The sponge gives a more medium to full coverage, and trying to evenly build the coverage with this texture was a bit challenging.
I find the finish looks quite heavy but doesn't feel too heavy and didn't cake up much. While I didn't wear it 24 hours, it lasted well when wearing it even after 12 hours. I had oils come through (which always happens) but not too badly , and the foundation didn't break up. It definitely lasted well and stayed quite matte. It performed well with no primer, but I'd be careful on that which primer you use as a tacky one would make blending even harder. It is a matte finish but didn't exacerbate any of my dry patches.
I like the squeeze bottle as it makes it easier to control the amount of product you get out. Buff 150 was a great match, it's nice that they have light enough foundations for my winter shade as foundations don't always and there's even lighter available.
