I am a big fan of the natural look, most guys at Uni thought I came in with no make-up (result!) and I am lucky enough to have pretty good skin so I don't need a lot of base make-up. Nonetheless here are my tips on achieving the perfect natural look!
A Good Base
When I first started with make-up I didn't use foundation and I always noticed how "off" it looked having a less-than-perfect base with well done eyes and cheeks. Concealer is the best bet - I usually use MAC Pro Longwear or Collection concealer on my blemishes and under my eyes and then powder it. Recently I've added foundation to the mix to make it even more flawless - just a light dab of Maybelline Fit Me which is a super light consistency. Keep it all natural with a solid, matte bronzer to add some colour to the face and then a tiny sweep of higlighter on the tops of the cheekbones. I personally don't think blush is a must - unless you naturally have red cheeks! However it's up to you.
This is probably not the most natural part as I naturally don't have long, thick lashes however I love to load my lashes with mascara to get them to steal the show. I think mascara just adds such an oomph to every look. I'm pretty fussy at this stage - I am close to tears when that damn mascara brush taps your eyelids and leaves a mark ... the injustice!
95% of the time I have a matte lip. As someone who has naturally quite large lips - wearing glossy products can look a bit ~unprofesh at times. Plus I nearly always wipe it off as it annoys me so satin/mattes are my best friend. Twig and Velvet Teddy by MAC are two of my faves, great neutrals that really pulls the whole look together.
