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; Caudalie.com) "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.
Clarins HydraQuench Cream-Mask

 

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.

B. Kamins Chemist Clear Control Purifying Masque

 

The Problem: Clogged pores and breakouts
The Cause: Acne may flare up in reaction to hormonal changes, a disruption in cell turnover, or products that irritate your skin.

The Remedy: B. Kamins Chemist Clear Control Purifying Masque ($45; BKamins.com) opens pores and soaks up excess oil. Glycolic and citric acids remove the oil, dirt, and dead cells that plug up pores. To counteract their drying effect, the clay-based formula also contains maple tree extract, an oil-free humectant, which attracts moisture and binds it to the skin.
LAB Perfect Mask

 

The Problem: Uneven skin tone, sagging
The Cause: Exposure to sun or pollution and loss of collagen and elastin.

The Remedy: 3LAB Perfect Mask ($120 for six; Nordstrom.com) has proven, effective antioxidants such as green tea and ginkgo biloba, and anti-irritants including licorice root extract. It also contains several cutting-edge ingredients that, when combined with a good daily antiaging skincare regimen, may help treat ruddy tones and fine lines: Nano-Claire GY, the first bioengineered growth-hormone-like material that speeds up cellular turnover; Matrixyl, a peptide that contributes to collagen synthesis; and SymGlucan, a moisturizing oat extract that promotes scar healing and wrinkle reduction.
