Yes. Daily use of sunscreen minimizes incidental sun damage especially to the face, neck and ears, and helps prevent skin cancer. Many skin products contain a sunscreen (moisturizers, foundations and make-ups) and are meant to be used daily.  For women, do not rely on make-up alone as we rarely apply enough of it to get to its stated SPF value. Use an all over moisturizer as well. Obviously the sunscreen should be reapplied throughout the day when participating in outdoor activities.
