I'm not really a collector of foundations to be honest, I tend to stick to what I like and not really change my ways, although I have collected some beauties over the past year or two.
(L - R Body Shop All Over Face Base, Bourjois Health Mix, Revlon Photo Ready, Mac Studio Fix Fluid, Estee Lauder Double Wear)
Body Shop All Over Face Base: The one and only non liquid foundation in my top five, I used this religiously for about three years back when I was around 17/18/19. It does give a very powdery finish but I used to suffer from oily skin so this was the only product that really stayed put. I tend to reserve this if I need to apply makeup at the speed of light, but I'd never be without one in my collection.
Bourjois Healthy Mix: Well considering I hated this when I first tried it back in the summer, I have eaten my words. I LOVE this, so natural and light, easy to blend, and although I do find I need a powder to set it I think it lasts a good 5/6 hours before I need to powder again (which is really good on my skin!)
Revlon Photo Ready: I can get past the 'shimmer particles' in this foundation because to be honest I can't even tell! This is my current every day go-to foundation, I've got it in a couple of shades (one was passed on by my Mum who wasn't really a fan) and I just reach for this every day. I don't think this necessarily needs a powder (unless I'm expecting an all day wear) and I think it gives a really flawless finish.
Mac Studio Fix Fluid: I used to swear by this and got a few of my friends on the band wagon with me, but I started to crave something a bit lighter on my skin so switched to lighter covering foundations like HM. I do still use this from time to time, and I think it's great to cover up last nights sins if you've had a particularly heavy one. I love that this is a mat foundation but I do tend to favour something a bit fresher these days.
Estee Lauder Double Wear: I don't know where to start with this, I'm officially in love. Yes I know I just said I don't like heavy foundations but a little bit of this goes a long way. I do reserve it for nights out or on days when I need a 7am - 12pm sort of coverage. I don't necessarily need a powder, although something light like Elf HD Powder is perfect with it. It goes on well, blends well, stays on all day, doesn't slip and slide, and most off all, looks gorgeous in my makeup collection.
Are any of these in your top five?
