Elemis has a reputation for high-quality products (even Kate Hudson’s a fan), and shoppers say the Marine Cream carries the torch with a “smooth and luxurious” formula so impressive, it convinced one person to replace the day cream they were devoted to for the last 10 years. With no regrets: “The silky texture and rapid absorption without any oiliness has given my skin a glow, and has made a noticeable difference in minimizing fine lines and wrinkles. Friends have noticed and commented!” To buy: $83 (was $128); amazon.com. It does especially great work on those hard-to-tone fine lines around their eyes, more users wrote: “Elemis hydrates like nobody’s business, and my skin shows it. It is remarkably softer.” Those consequences are thanks to a formula that draws on marine extracts like chlorella and padina pavonica algae, which the brand says reduce the look of fine lines within weeks. Algae is a hot topic in the beauty world right now: Reese Witherspoon’s go-to skincare brand, Biossance, relies on it, as does the Acure eye cream that sucks shoppers’ eye bags back into their face.
