Got a skin problem? Chances are, there's a mask out there designed to address it. Hundreds of face masks promise benefits from antiaging and refreshing tired skin to hydrating and fighting acne. To help you find the best mask, we asked Audrey Kunin, M.D., a dermatologist in Kansas City, Missouri, and founder of DermaDoctor.com, for tips and recommendations.

Antiaging
Look for: Alpha hydroxy acids (ahas), the most popular of which is glycolic acid. Beta hydroxy acids (bhas), such as salicylic acid, diminish fine lines and skin discolorations. Kunin's pick: M.D. Forte Skin Rejuvenation Hydra-Masque ($24.50)

Refreshing
Look for: Soothing ingredients, such as chamomile, comfort tired-looking skin; fruit and vegetable extracts, such as papaya and cucumber, alleviate puffiness and redness. Kunin's picks: Neova Gentle Purifying Mask ($24); Peter Thomas Roth Cucumber Gel Masque ($40)

Hydrating
Look for: Water, a high concentration of moisturizers, and exfoliants. Kunin's picks: Z. Bigatti Restoration Dew Hydrating Facial Mask ($98), ahava Mud Masque for Normal to Dry Skin ($33.60)

Antiacne/Oiliness
Look for: Clay-based products, particularly those with kaolin and bentonite, draw out dirt. If you have sensitive skin, look for less-drying silica instead. Sulfur helps kill bacteria on the skin's surface. Kunin's picks: Cellex-C Betaplex Clear Complexion Mask ($39), Peter Thomas Roth Therapeutic Sulfur Masque ($40)
