The opalescent MAC Cream Coloring Base in Luna is powdery and light, but perfect for creating that bright glow around the half-halo of the eye. Rommy "danced" an eye shadow brush along the highest point of India's cheek—stopping when aligned with the outer corner of the iris. Paired with earrings by Beck Jewels.

A pink highlighter like Bobbi Brown's powder brick in Pink Glow never fails to scream "FUN!" because, well, it's pink and sparkly. Get it all over (the whole cheekbone—or more!) with one swipe of Make Up For Ever's #142 flat and fluffy brush. Blush and glow in one. Paired with earrings by Mateo New York.

A light dusting is fine, but with the classic Becca Shimmering Skin Perfector in Pearl, Rommy opted for a dense, duo-fiber Real Techniques brush for ultimate pigment pickup. The silver sheen is cool (literally) and works just as well as an eyeshadow. Paired with earrings by Carole Shashona.

Now, if you're working with something like RMS's Living Luminizer, you're going to want to sink your fingers into that creamy texture. Apply by "tapping it into the skin with your ring finger and then go over the edges with a dry finger to lightly diffuse any hard lines," Rommy says. This is the key for having it melt into skin.

Contrary to popular belief, you don't actually need to be Pat McGrath to get the most out of the Pat McGrath Skin Fetish Illuminator Kit. (Though it helps.) Here, Rommy was working with the kit in Nude—he started by highlighting with the nude shimmer side of the stick and then layering "the balm directly on top of the cheekbone and lightly on the apple of the cheek for that ultimate glass skin." Paired with earrings by Leigh Miller and Pat McGrath 001 Gold on the lips.

For something ever so subtle—easy enough to mix into foundation or a moisturizer—Rommy went with Nars Copacabana Illuminator Liquid, working it into the skin quickly before it dries down to a powdery, stay-all-day kind of situation. The perfect look when only you and the ones you love want to know your highlighter is there. Paired with earrings by Paula Mendoza.

And sometimes all you need is a spritz. Of Caudalie Beauty Elixir, of course—the classic. You can never mist too much, so tilt your head back and let it fall all over you, focusing on catching the droplets on the high points of your face. Repeat as necessary. If this isn't a doable summer look, what is? Paired with earrings by Carole Shashona.
