Fiji Blend Loss Gloss and Loss Gloss Blast ($13 and $15; www.fijiblend.com) The product: Loss Gloss incorporates St. Johns wort and methionine (found naturally in sesame seeds) as its appetite suppressants, while Loss Gloss Blast also contains caffeine, ginseng and guarana for an added energy boost. Both products feature moisturizing almond, papaya and monoi oils, and come in a SPF 25 formulation. The test: One swipe of Loss Gloss Blast gave lips an iridescent shine, while the Peppermint Pattie scent (surprisingly) satisfied cravings. Loss Gloss, which smells like maple syrup, didnt leave us wanting pancakes, but it needed to be reapplied within the hour. The verdict: Probably the thickest and the strongest smelling of all the glosses, the Loss Gloss Blast seemed to have the most immediate effect on suppressing our impulse to snack, but the tacky formula left lips feeling dry.
