The brand's first pout plumper to date, the formula goes on smooth, boasts a sweet vanilla scent, and imparts an ever-so-subtle, temporary tingle (it's a far cry from the burning sensation of most lip volumizers). For this reason, Plushglass will be especially appealing to those seeking a little pain-free fullness. Over time, the product (which contains vanillyl butyl ether, lemon oil, and soybean and licorice extracts) is designed to enhance the condition of lips, meaning that the more you swipe on the sponge-tip gloss, the smoother your pout will feel.
