Clinicians Complex Lip Enhancer - Almost Nude gives full, luscious lips and barely-there color. This lip-boosting formula is infused with niacin, a vasodilator derived from vitamin B that increases blood flow and circulation to instantly create plumper lips. Peptides within the formula promote collagen and hyaluronic acid production for long-term plumping effects. Retinol and vitamin E within the lip enhancer rejuvenate and protect lips from environmental damage. It takes just minutes for a plumping effect that lasts hours. Almost nude is a tame, neutral golden shade.
