Sunscreen Recommended During Long, Hot Summer Days

(Undated) -- Dermatologist Dr. Ellen Marmur says Americans really don't use enough sunscreen. Dr. Marmur says long-term sun exposure and sunburns can lead to skin cancer and also premature skin aging. She says you can minimize this by using sunscreen on sun-exposed places like your face, your ears, the back of your neck, your chest and on your arms and hands.
