The contenders: Fast-acting topical treatments promising to diminish the look of fine lines and wrinkles. These temporary smoothers work by either plumping up the skin or filling in creases with a spackle-like serum.

Testing time: 15 minutes in the lab (to test the instant claims); one week at home.

And the winners are...Boots No7 Intensive Line Filler ($18, Target) and Olay Regenerist Filling + Sealing Wrinkle Treatment ($19, drugstores) showed their might in somewhat different areas when our experts and panelists rated skin changes in three wrinkle-prone hot spots: the forehead and around the eyes and mouth. Olay ranked highest in the lab for reducing forehead lines, and came in first with consumers for minimizing wrinkles all over the face. Boots won for ease of use and performed slightly better than Olay on eye wrinkles. As one tester reported about the Boots: "Very fast results, not irritating, and it gave me a fresh look when I was tired."

Tip: The wrinkle-flattening effects our lab experts noted on the Visia 15 minutes after application were definitely subtle. But if you don't have a cosmetic dermatologist on your speed dial, or months to wait for your skin care to kick in, our winners can provide you with a quick pick-me-up.
