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.
