No7 Beautifully Matte & Beautiful Skin

Hello Lovelies! So lately I've been surfing the interwebs, just watching alot of videos and reading blog posts and realized that actually, alot of people use makeup primers in their daily makeup routines. See I never thought makeup primers actually worked all that well but alot of people still seemed to be raving about them and so I thought I'd join in with the rave and purchase my own to try out. I came across No7's Beautifully Matte Makeup Base in boots which I believe is £10.50 which can seem alot to pay for a makeup base however I totally reassure you, it's worth it. For anyone who doesn't know what a makeup primer is, its at its most basic level a cream of which you apply to your face which makes your makeup stay on much longer through out the day.
First of all when you apply it, it's really thick and its got a really nice matte feel to it. It goes on your skin really easily and softly and at first I was abit sceptical to whether it'll work or how long it'll last. I don't think anyone will ever find a primer that will keep your makeup looking perfect for hours on end however this is still a really good primer. I didn't exscatly count how long it lasted, however I did notice it gave my foundation a smoother look on my skin and more of a matte look to it too. I think it's a brilliant primer, it keeps my makeup on for that little bit longer and although the price is a little steep I'm sure it'll be worth paying for, it's definitely something I'm repurchasing. 
I also came across No7's Beautiful Skin BB Cream for Dry/Very Dry Skin. I suffer from dry skin and I'm always on the hunt for new and better creams as I'm sure I'm not the only one who thinks dry skin isn't exscatly the most attractive look. When I first tried this, the cream was actually a really daunting dark, almost foundation cream however if you rub the cream in well enough, there will be no coloring left on your skin what so ever. I've been using this cream for a few weeks now and I have to say I haven't actually seen a huge deal of improvement or difference in my skin or my dry patches which is a really big shame. I picked this up for £12.95 which can also be quite a steep price for a cream however I don't think this is the right cream for my skin as its not made any major improvements.
Have you tried any of these products?
