The first one technically isn't even a highlighter. It's Bobbi Brown's Extra Soothing Balm. A skincare item, I use this on my cheeks if I'm in the mood for a dewy cheeks with very subtle glow. I love the herbal scent this product has, and it feels great and nourishing on my skin.
For a less subtle look, and a more obvious glow, I use RMS Beauty Living Luminizer. I'm a big fan of organic products, and this brand is no exception. The line uses organic, non toxic ingredients that are meant to be good for the skin. The glow from this product is still pretty subtle, and I like the radiant look it provides.
Now for the product that gives the biggest highlighting effect of the three, Nars Multiple in Copacabana. I adore this product as it highlights skin beautifully and gives an amazing pearly sheen. Now that i think about it, I haven't used this product for awhile. I must resurrect it!
