With so much of your skin showing in great summer fashions, it makes sense to pretty it up. One way to do that is to apply a bit of sparkle and glow to your eyes, lips, cheeks, shoulders and collarbone. With MAC multi-purpose glitter ($16.50 for 0.26 oz.) you can transform the make-up you already own — just add a bit of this product to it — or apply the glitter directly to your skin. The effects will be dazzling. Bloom’s shimmer body cream ($24) isn’t designed to blend with other makeup, but it does promise to add a subtle sheen to your skin. Plus, it’s scented with lavender oil to make you smell fantastic. Make Up For Ever was one of the first companies to make skin powder that captures and reflects light like a gem. A little bit of their pearly, iridescent Star powder ($18 for 0.09  oz., pictured), available in a complete painter’s palette of colors for mixing and shading, goes a long way. If maximum glitter is what you want, get the Diamond powder ($24 for 0.07 oz.). It’s composed almost entirely of pure synthetic mother-of-pearl and will “radiate extreme brilliance” upon application. For the eyes, be the first to own a Sparkle eye pencil ($17.50), which is available as a limited edition sneak preview item from Prescriptives. (Full product line to be launched in the fall.) Offered in plum and midnight blue, this eye pencil boasts intense color with dramatic sparkle. Over at Urban Decay, there’s Heavy Metal glitter eye gel ($18), eyeliner ($18) and, for the lips, a sparkler pen ($10). Turn heads with this make-up, but be careful not to blind anyone
