When it comes to moisturizing, everyone’s skin has different needs. But there’s one product that we can all benefit from adding to our skincare routines: hydrating serum.

If you’ve never tried one before, you should know that it’s meant to be used after cleansing and exfoliating, and before moisturizer and sunscreen. Because the texture is fluid—ranging from thin and watery to milky or gel-like—it’s weightless and perfect for layering.

Best of all, hydrating serum is good for every skin type. That’s because it’s packed with a high concentration of humectants, which are ingredients that attract and bind water to plump and moisturize your skin. All you need are a few drops to boost your skin’s moisture level, whether you’re dry, oily or in between.

Here’s what to look for in a hydrating serum, plus the best products to try now.
