Sunscreen recommendations that won't leave my skin greasy or with that silver-ish tone

[AdrenalineFudge]

Ideally a 20+ spf, but what would be good is if I could find one with primer incorporated into it so I could kill two birds with one stone.

Boots Soltan Dry Touch. Must be the Dry Touch one, the normal ones are greasy. It comes in SPF 30 and 50. It's £6, so very good value. I used to use Clinique before I tried this - many sunscreens irritate my skin.
