Matifying primer recommendations please?

[AngelicCurls]

I currently use Clinique pore minimiser serum as a base either on its own or under foundation as it gives a nice Matt finish. Recently tho it's been less matt towards the end of the day and I'm hoping people will have recommendations for a specific mattidying primer,

Smashbox does a mattifying primer. Its purple, you can ask for a sample or buy the small version which is like £10-15 i think

Smashbox or No7.

I use biore uv milk sunscreen (not the biore watery essence sunscreen) as a mattifying primer - its spf50, around £7 on eBay or amazon

I never thought I'd say this but Barry M does a good one and I heard a rumour that Wilkos primer is also very good too.

After tryings loads of expensive primers I'm loving the primark one.

Thanks all, I've got samples of the smashbox and no7 ones to try
