For your skincare routine to work at its best, hydration must come first. When skin is properly hydrated, it looks smoother, plumper, and more radiant, and everything layered on top will work better, too. But as temperatures drop (it's brutal in NYC right now) and indoor heat dries out the air, maintaining that healthy moisture balance can suddenly feel like a ton of extra effort. The good news? According to dermatologists, achieving well-hydrated skin doesn’t require a total routine overhaul—just the right hydrating serum for your skin type.

“Because serums have smaller molecules than typical moisturizers, they can penetrate deeper into the skin, making them ideal for delivering targeted treatments. These serums are lightweight in texture, thinner, and fluid, allowing them to absorb quickly into the skin,” says David J Goldberg, MD.

That said, choosing the right formula matters. Different hydrating serums are designed to address various skin concerns, and ingredients are the easiest way to help narrow down your options. “Dry skin benefits from richer formulas with ceramides and antioxidants, while oily or acne-prone skin does better with lightweight, water-based serums that feature humectants like hyaluronic acid and glycerin,” explains Dendy Engelman, MD. “Those with sensitive skin should look for soothing, barrier-repairing ingredients that help calm and protect the complexion.”

After consulting dermatologists and testing several top-rated formulas, I rounded up the best hydrating serums that deliver moisture, visible plumpness, and a lasting glow to help keep your complexion from becoming dull and dehydrated during the harsh winter.

The Best Hydating Serums

What Is the Best Serum for Deep Hydration?

Finding the best serum for deep hydration depends on your skin type and the ingredients. "Different types of hyaluronic acid and different molecular weights of hyaluronic acid penetrate to different skin layers for comprehensive hydration," says Dr. Goldberg. Look for serums that have a mix of molecular weights, as well as ingredients like glycerin, ceramides, peptides, and squalane.

How Do I Choose the Right Hydrating Serum?

"Dry skin benefits from richer formulas with ceramides and antioxidants, while oily or acne-prone skin does better with lightweight, water-based serums rich in hyaluronic acid and glycerin. Sensitive skin types should look for soothing, barrier-repairing ingredients," explains Dr. Engelman. You'll also want to consider the serum's price point and how it interacts with your other skincare products. Finally, texture is a big factor—and largely personal preference. I prefer a more watery serum, but you might prefer a milky one.
