title: Sunlight and protection of the skin.
abstract: Sunburn, wrinkling and malignancies are the frequent results of excessive sun exposure. Photosensitivity and photoallergic or phototoxic reactions are less commonly observed. Sunscreens containing para-aminobenzoic acid (PABA), PABA esters and benzophenones offer substantial protection, allowing even fair-skinned persons to participate freely in outdoor activities. These products are now rated and assigned a sun protection factor (SPF). Their routine use should be encouraged.
