In summer, I generally use very little foundation, I prefer a BB Cream or a Tinted moisturiser and of course I can't be without highlighter in summer.
My favourite highlighter at the moment must be Revlon Photoready Skinlights - as I use it almost everyday. In my opinion the Revlon Photoready Skinlights Highlighters are the perfect dupes for MAC Lustre drops.
Although not cheap at € 18.99, I still find its a good value for money as you get loads of product and
if you only use it as a highlighter on the high-points of your face, than this could easily last you a year or more.
The shade Bare light suits my skin tone perfectly and it just looks I have an amazing beautifully glowing skin. As you can see below in the photo I am wearing the 100 Bare Light shade as a primer all over my fave and I have only used a concealer where I needed to conceal the blemishes.
100 Bare Light - suit most lighter and warmer complexions
200 Pink Light - suits very pale and cooler complexions
300 Peach Light - suits darker complexions and also looks great on tanned skin
