Caudalie Vinoperfect Radiance Revealing Mask


The Problem: Lackluster skin
The Cause: When you don't properly cleanse or exfoliate, dead skin cells build up on the surface of your face, dulling your complexion.

The Remedy: The grape extract in Caudalíe Vinoperfect Radiance Revealing Mask ($46; "dissolves the material that holds dead skin cells together," says Francesca Fusco, MD, a New York City dermatologist. Applying the citrus-scented cream with the soft, built-in brush makes the process feel as luxurious as a spa treatment.

The Problem: Dryness
The Cause: You may be using antiaging or acne products containing retinol or benzoyl peroxide, or you're exposed to dry heat, or you're not drinking enough fluids. Or: You may simply have chronically parched skin.

The Remedy: The katafray bark in Clarins HydraQuench Cream-Mask ($35, department stores) encourages the production of a protein essential to forming new cells—and when cells are new, they retain more moisture.
