I don't really wear foundation that much as I am lucky enough to be blessed with pretty clear skin. I never get spots and hardly ever suffer from blemishes so can get away with just using tinted moisturiser. But, on the days where I'm not feeling so good (mostly in winter, my nose area goes a bit red) I like to use Bourjois Healthy Mix foundation in shade 52.
I like the fact it's a medium coverage, its just enough to hide any redness but not make me look like a cake. The colour suits me well and I love the smell of it. The fact it has fruity ingredients is pretty appealing too. I only wear it under my eyes, around my nose and sometimes on my chin and it lasts all day :-)
I have tried other foundations in the past but my skin can get really dry, this foundation doesn't make my skin flake at all, whereas I've found other foundations can.
I've heard some good reviews about Bourjois Healthy Mix Gel Serum foundation, I'm quite eager to give this a try when this one runs out.
