The best hydrating serums we tested
When your skin is looking dull or dry, that usually means it’s time to ramp up your skin care routine. Hydrating serums are an easy place to start. They deliver long-lasting hydration, typically leaving skin soft, glowy and ultra-moisturized.
To find the best hydrating serums, we had 10 CNN Underscored staffers with a wide range of skin types put a variety of formulas to the test, from affordable staples to luxe picks. After daily use and careful comparison, three standout serums emerged, with our overall pick being a drugstore find that costs only $22.
Best hydrating serum
Deals editor Jacqueline Saguin found Neutrogena’s Hydro Boost serum deeply hydrating, lightweight and gentle on her sensitive, eczema-prone skin. She appreciated its simple, fragrance-free formula with nourishing ingredients like hyaluronic acid and glycerin.
Best hydrating serum for dry skin
Home and gifts editor Amina Lake Patel tested The Ordinary Multi-Peptide + HA Serum and loved its lightweight feel, quick absorption and hydrating, nongreasy formula. A longtime fan of the brand, she plans to keep using the $20 serum.
Best hydrating serum for textured skin
Testing writer Carolina Gazal, who battles cystic acne and scars, found this serum from CosRX to be a soothing, breakout-friendly solution that deeply hydrated her skin without irritation. Despite its gooey texture, she came to rely on the ultra-nourishing formula and would gladly repurchase it for its skin-repairing benefits and affordable $25 price tag.
