Deep-Cleaning Cheat Sheet

Cleansers: Look for cream cleansers if you have dehydrated and easily irritated skin. Cleansers in gel form are better suited to oily or combination skin, as they're likely to contain ingredients that lift oils and exfoliate. You've found the right cleanser if after washing it doesn't feel too dry or look oily.

Exfoliators: Physical exfoliants contain abrasive particles that sweep away dead cells. Chemical exfoliants, which can irritate very sensitive complexions, are formulated with salicylic acid, fruit enzymes or alpha hydroxy acids (AHAs) — like glycolic acid (from sugar cane), lactic acid (from milk) and citric acid (from citrus fruits). Don't over-exfoliate: Once every two to four days should be plenty.

Toners: Toners were created to normalize the skin's pH level after cleansing. Today's face washes are usually pH balanced, although some exfoliating products can change skin's pH. Some toners also contain hydrating ingredients.

Masks: Ingredients in masks really get soaked up by the skin. If you have a dry complexion, look for soothing botanical oils or shea butter. Oilier complexion should look for products with AHAs or salicylic acid, which get deep into pores to thoroughly unclog them.
