Bronze Platine Mascara Gel Irise ($34.00 for 0.28 oz.) is described as a “platinum bronze.” It’s a warm-toned, metallic bronze with gold and copper shimmer. It’s supposed to be a top coat for lashes and deliver “sheer, bronze-platinum iridescence,” which can be applied over bare lashes or over black mascara. I really wasn’t able to see difference when applied over bare lashes. I thought–at best–it lightened my black-brown lashes a little bit, but I could have been wishing that given how subtle the impact was. I didn’t see sparkle, shimmer, or color change. Maybe my lashes are too fine to show the effect or catch the sparkles, because when I applied over mascara, I was able to see very, very tiny bits of sparkle sparsely over the lashes. I think the effect is too subtle to really merit the product; you could get a similar effect by dusting a loose, shimmery eyeshadow on lashes (or mixed with clear brow gel/mascara for better hold). You can also use liquid glitter eyeliner and paint across the tips of lashes for a sparkly effect. I don’t have any actual dupes for this, as I can’t say I’ve tried many (possibly none previously) top coats for lashes. Normally, I’d consider this a loss for dark lashes like mine but Chanel actually expects this to be layered over black mascara, so that’s not really an excuse.
