Can anyone recommend me a good primer which as chemical free as poss?

[sleepysox]

As the title says, I'm after a decent primer.

I've been using a sample of L'oreal Studio Secrets and found it good, but a bit drying on my cheekbones.

I'd never used a primer before and didn't realise what i was missing! My face looked like it had been airbrushed when I looked in the mirror and it made my foundation last much longer.

So, I'm after a primer which is as natural as possible, as I have sensitive skin and it reacts badly to chemicals, heavily perfumed products, AHAs etc. I tend to use Bare Minerals make up and Estee Lauder.

I have sensitive skin, oily T zone and dry cheek bones.

HOpe someone can help,

If noone has any 'natural' suggestions, I'm open to anything which is suitable for senstive skin!

soap and glory bright here bright now?

What about the Bare Escentuals Prime Time? Not tried it myself but I hear good things about it. I think all primers are silicone based (could be wrong about that) which I think can be quite drying so I'm not sure if there is such a thing as a chemical-free one. I'll watch with interest though.

Thanks for the suggestions.
Have read up the reviews on soap and glory and BE on make up alley, and have probably decided upon Inika primer (organic and nourishing).

I'll post back when I've bought some and tried it.
