Kenneth Howe, M.D., a board-certified dermatologist in New York City, explains that “in contrast to moisturizers, serums don’t contain air-tight, occlusive ingredients, which allow them to penetrate more deeply into the epidermis, carrying their active ingredients with them.”
Another reason why these facial serums are a mainstay for skin-care novices and lovers alike? The good ‘ol feel factor. “Serums are the new moisturizers,” New York City-based board-certified dermatologist Ellen Marmur, M.D., tells Allure. “They are perfect for layering — like a primer on clean skin before makeup or sunscreen.”
Luckily, there’s a world of options out there, including vitamin C serums and thirst-quenching formulas infused with hyaluronic acid, to suit whatever your skin type and concerns may be. In fact, we’ve got 26 of the best face serums below (many of them recommended by dermatologists, and some of them tested by us), so keep scrolling to find your new favorite.
