High spf budget face cream?

[poshredrose]

I have two bcc on face due to be removed and know I'm at a higher risk of getting more. I am covered with moles and freckles all over and am looking for a very budget friendly day cream.
My skin is oily but dry, I've recently tried a bb cream with spf 50 but i NEVER wear makeup and even the slight tint was too much.
I tried Aldi but that irritated my eyes. I'm currently using something from Asda but thats only spf15. I ordered a spray from amazon but don't feel like it covers.
I have a budget of about £10 at most and can't keep buying creams to try, need a good one. Can anyone recommend something?
Thanks

Body Shop do an SPF30 vitamin E cream that's around £15. There's nearly always vouchers to be found for 20-40% off, which should bring it into line with your budget.

Thank you for the recommendations. I ordered the Altruist one from amazon. It's the same make as the spray I had tried and so far so good, certainly no irritated eyes with this one.
