Vitamin D is critical to human health and the best source is from natural UVB light. However, contrary to the benefits gained are the well-documented damaging effects of sun exposure. In response, described here as a complementary approach to sun care is the development of an accurate gauge of UV exposure to produce optimum levels of vitamin D before sunburn results.

Skin occlusion is a complex issue. Occlusion usually means the skin is covered directly or indirectly by impermeable films or substances, but certain topical vehicles that contain fats and/or polymer oils may also generate occlusive effects. They speed healing, but can also encourage the formation of bacteria. In the following excerpt, Zhai, MD, and Maibach, MD, review recent studies in various modes and methods of occlusion.
