Putting on a good primer is essential after moisturiser. Not only will it mattify your skin, but it results in much longer lasting make-up too which is definitely needed throughout the warmer months. My pick is the Clarins Instant Smooth primer, but there are some pretty good ones on the high street too. I just find the Clarins smooths over any imperfections, reduces redness and make my make-up long lasting like I've never found before.
Avoid a heavy base
I don't really have any tinted moisturisers or BB creams I've really loved, so I usually avoid any sort of foundation or base. I use a heavy duty concealer ( the Seventeen Phwoarr Paint being my favourite ) to cover any blemishes or dark circles, and blend in with my Real Techniques Expert Face Brush which adds a little bit more coverage having such dense bristles.
Pop on a powder
After a light base, a good mattifying powder is essential to add that extra step to hold everything in place. I love the Vichy Dermablend Setting Powder - it blends in effortlessly, mattifies the skin and keeps all my make-up in place.
Cream blush is a no-go
I really love cream blush and highlights for creating a dewy glow, but on the really hot days your skin will be doing that for you. Stick to powder products, and pick some good quality ones with great lasting power. The Urban Decay Naked Flushed palettes are a perfect 3-in-1 that have lots of pretty shades and stick around 'til the evenings, even on the warmest of days.
I avoid any fussy make-up that could smudge - this means I usually wave goodbye to my beloved cat eye flicks until I can be sure they won't end up smudged above my eye, and if I do use an eyeshadow, it's just a simple one colour over the lid, nothing too complicated. I focus on the mascara, and use a matte lipstick - if the rest of your face is looking a bit shiny, a great bright, matte lip colour can take the focus away from that. The Bourjois Velvet Lipsticks are absolutely perfect for this, a gorgeous matte formula which is so long lasting, not even a top up is required after eating or drinking, my favourite is the shade 'Ole Flamingo'.
