Product name: Eyeko's Super Size Shine
Claim: This product, which comes in an easy-flow pen with a brush applicator, is supposed to enhance the shape and texture of your lips with regular use. The company says it increases volume by compensating for lack of collagen in the lips. It's supposed to be so lightweight that it can be used as a base or a gloss and is meant to taste like spearmint.
Tester says: "I tried it, waiting for the 'minty fresh' effect, but no luck. It's a smooth everyday gloss, but it did nothing for my lack of collagen. I liked the penlike applicator, though. It was fun to paint my lips with gloss that came out of a brush. It was totally nonsticky, which was great. My lips felt noticeably softer and smoother, but I had to keep reapplying. This is definitely not long lasting, and with the constant retouches, you can run through the product pretty quickly.

Product name: DuWop Venom Gloss
Claim: This product is purportedly the queen of all lip plumpers. It's said to be a long-lasting gloss that increases circulation and lip size with its blend of cinnamon and ginger oils. The taste is supposed to be spicy, and the feel tingly. The intended result: shiny, glossy, bee-stung lips.
Tester says: "Who said 'No pain, no gain'? Whoever it was was talking about this lip plumper. As the name suggests, it's not for the fainthearted. It really stings (do not apply to chapped, broken lips!), but the results are remarkably quick and dramatic. For me, the pain was worth the plumpness, but unfortunately, the results are temporary. Lip Venom flushes, plumps and irritates beyond compare. If you need sexy lips tonight, make this truly wicked gloss your one-night stand.
