Puffiness is a buildup of fluid and blood under the eyes. Some studies show that caffeine can help circulation, which could reduce puffiness. Other studies show that cold temperatures are just as effective to treat puffiness. That's why some people refrigerate their eye creams. This Olay eye cream is designed to deliver serious skin-brightening benefits with vitamins B3 and C as well as caffeine. The light reflectors and brightening pigments instantly help even the appearance of the skin, too. Peptides and vitamin E round out the formula to provide a refreshed, dewy glow. "Nothing has helped my dark circles under my eyes like this product," one reviewer wrote. Lozina said to take your specific skin concerns into consideration when choosing an eye cream. If you have oily skin, avoid eye creams that are oil-based or petroleum-based. Wax-based eye creams, like those with carnauba wax, can cause breakouts. “If you have dry skin, look for eye creams that have some oil, hyaluronic acid and peptides. These ingredients will help to hydrate your skin and stimulate collagen and elastin production,” she says.
