Winner

Dr. Hauschka Skin Care Moisturizing Mask, $48
“This made my skin moist and supple, like I had just had a facial,” said one tester. With plant oils and beeswax, the mask (shown) seals in moisture by forming a protective, nongreasy layer that stays on the skin after you wash your face.

Runner-Up

Lancôme Hydra-Intense Masque, $27
This mask contains extracts from Imperata cylindrica, a grass that helps retain water. What that meant for testers: Their skin was hydrated for hours and felt “nice and soft.”
