Too Faced's LIP INJECTION extreme lip plumping potion, a crystal-clear, liquid lip volumizer that plumps up lips for results that last up to 4 hours. LIP INJECTION contains a natural Vitamin B derivative that allows for increased circulation to the lip area creating phenomenal lip-plumping action and increased lip volume. Just apply a thin coat of this liquid lip treatment on lips with the applicator brush. A light tingling sensation may be experienced when LIP INJECTION is applied that can last up to 5 minutes. Afterwards, lips look 20% fuller, plumper and juicier! Lip color or gloss can also be applied after LIP INJECTION has dried for a more intensely vibrant lip look. Directions For Use: Apply lip injection on clean lips, let sit for 5 minutes. Wipe off and apply lip color for a full, fat, matte lip.
