And the winner is... Boots No7 Protect & Perfect Intense Beauty Serum ($23, amazon.com or Target) was a superior performer overall and shared the highest consumer score with the second-place finisher, Mary Kay (details to follow).

"It's easy to apply and nongreasy," said one panelist. "My skin has never looked better."
