If You Buy Any Skin-Care Product This Month, Make It One of These Editor-Approved Picks

"Mara and its facial oils are legendary, so I expected nothing less from the brand's new Sea Vitamin C Sérum ($96). The supercharged formula is infused with 15 percent THD ascorbate — a form of vitamin C — plus marine botanicals and fruit extracts to brighten your complexion for an all-over glow. It absorbs quickly and leaves skin feeling hydrated and instantly dewy. It's almost too good (and too pretty) to use. Almost." — JH
