What Real Beauty Editors Are Buying This May

Some serums can actually fall closer to the moisturizer end of the spectrum. They are heavy and creamy, leaving your face with a sticky feeling. This Erno Laszlo Hydra Therapy Refresh Infusion ($100) is actually closer to an essence (but with way more antiaging ingredients). The liquid immediately disappears into your skin and leaves no residue behind. I love to add a few pumps to my foundation for a dewy, glowing finish.
