Benefit Stay Don’t Stray in Medium/Deep ($26.00 for 0.33 fl. oz.) is a liquid product that can be used an eyeshadow base to keep eyeshadow in place and keep the color looking true as well as to keep concealer in place. I reviewed the formula when it originally debuted, and as I said then and can reiterate now: it is a fantastic product. The major downside was the packaging, which Benefit had used a pump-type dispenser that dispensed far and away too much product. Like the amount you’d need to cover your face, rather than just underneath your eye or on the lid.
