And you thought winter was hard on your skin! Summer is tough too – hot weather and humidity can clog pores and make skin feel greasy.

Two rules to remember if you have acne: Don’t pop your zits (this prolongs the healing process) and don’t skip your moisturizer. Drying out your skin can stimulate more oil production.

Use a cleanser and a moisturizer that are oil-free, suggests dermatologist Dr. Jensen Yeung, director of The Psoriasis Clinic and co-director of the melanoma pigmented lesion clinic at Women’s College Hospital.

Yeung likes Clean & Clear products because they have been studied extensively and formulated carefully for both teenage and adult acne.

Try Clean & Clear Deep Action Refreshing Gel Cleanser to clean your skin, and then Clean & Clear Morning Burst Shine Control Moisturizer to hydrate skin all day.

“It generally takes around four weeks to see noticeable results,” says Yeung, who adds that it is important when starting a new skin-care regime to follow instructions carefully. Don’t use the products more often or less often than advised.
