Bobbi Brown Island is a very warm-toned, light gold with a pearl finish. It is a permanent blush that retails for $36.00 and contains 0.31 oz.
Bobbi Brown Island Glow Stick ($36.00 for 0.31 oz.) is medium, golden bronze with warm undertones and a pearly sheen. It had a dewy finish on the skin, as the formula never dried down. While the finish was always luminous, it had terrible wear--on its own, it had slid around noticeably on my skin after four hours of wear. When I tried it over my liquid foundation, it moved my base around a ton and created a lot of patchiness within two hours of wear. It had sheer coverage, and the pearl in this particular shade made it look spectacular but just required so much maintenance, care, and touch-ups.
It's supposed to be a "creamy, lightweight highlighter" with "sheer" coverage that gives "an instant, sun-kissed glow that lasts all day." The formula was very emollient with a lot of slip and wetness; it never dried down and always felt slick on the skin. All of the shades I tried were sheer, and they were not buildable, so several shades ended up looking very similar on my skin tone (but may look more or less different on other skin tones/undertones). The emollient feel of the formula did not play well with products (primers, cream/powder/liquid foundations or blushes).
