We've only been toting Jane Iredale's powder sunscreen in our bags for less than 24 hours, but already, we can't be without it.

Powder-Me SPF 30 is a translucent powder that slips on skin like silk, leaving no trace of grease, goop or that icky sunscreen scent that comes with most sunscreen lotions. The powder provides full physical protection with active ingredient titanium dioxide, and contains no artificial preservatives or parabens, just like the rest of Iredale's products.

The dry sunscreen dispenses through a sponge, and contains a clever little mirror to make sure on-the-go touch-ups are blended in. We found the powder especially easy to apply on sun-sensitive areas like the ears and neck, where the undesirable slick of lotions often keeps us from applying enough sunscreen.

"Powder-Me contains full UVA and UVB protection. You can think of UVA as causing aging damage, while UVB gives you the burn," Iredale told a group of beauty writers over lunch at New York's Serafina Fabulous Grill, where the elegant Brit distributed full-sized samples of the product to al fresco dining patrons in celebration of the summer solstice.

When applying the product, we found that a few taps to dispense powder followed by a quick blending with the sponge made for an even spread.

Whatever your preferred technique, make sure to blend the powder over the skin for full protection. Iredale shared a story to the laughs of the room of an associate's husband who begrudgingly tapped the powder in a couple of spots on his back at his wife's insistence -- only to emerge lobster-red from hours spent in the sun, with a couple of distinct round spots of perfectly protected light skin where the product had been applied.
