I use body shops moisturising foundation I find their colours are pretty good
I have used body shop in the past and really liked them too..
The one brand which actually surprised me was tesco's own brand Barbara Daily - I got a tub of the "face lift" its very light and illuminates the skin without taking away any of my freckles, I also bought the highlighter and foundation and I love using all three together - it was mega cheap too.
I use double wear these days when I feel like wearing makeup - which is as thick as a mask so completely useless to your needs!!
I have an Almay foundation (you can get them for £4-£5 in the Original Factory shop) and i love it! Failing that, BB cream is always a good bet teamed with some MAC select cover concealer to boost the coverage where needed. I use Maybelline dream fresh BB.
I've swapped all my makeup and toiletries for cruelty free stuff. I didn't want to buy online and couldn't be bothered to travel all the way to Birmingham to Selfridges or whatever.
I'm using good old Marks & Spencer... I have to combine 2 shades because I'm between the ivory and the sand colours but I'm happy with the results for a very reasonable price. (also got powder, bronzer, eyebrow pencil, eyeliner pen - the only one I'm not keen on- and mascara.)
I was recently in Boots and tried the LO'real True Match foundation whereby they test your skin pigmentation with a small machine, and I must admit, I was very impressed. They have ranges from matt to lighter bases and cost £8 +.
I have an absolutely terrible time getting foundations to match because I'm so pale but I've been using Illamsqua's second palest shade and it's a perfect match, unfortunately it's not that suited to dry skin, so I use Garnier BB cream as a base and the Illamasqua stuff as a concealer under my eyes and on any blemishes. It seems to work quite well.
