Background. Since skin of the dorsal hands is a known site for the development of cutaneous squamous cell carcinoma, an epidemiologic investigation was needed to determine if beachgoers apply sunscreen to the dorsal aspect of their hands as frequently as they apply it to other skin sites. Aim. The aim of the current study was to compare the use of sunscreen on the dorsal hands to other areas of...

Cyanobacteria have two types of sunscreen pigments, scytonemin and mycosporine-like amino acids (MAAs). These secondary metabolites are thought to play multiple roles against several environmental stresses such as UV radiation and desiccation. Not only the large molar absorption coefficients of these sunscreen pigments, but also their antioxidative properties may be necessary for the protection...

Sun care products have evolved extensively during the past four decades. In the 1970s and 1980s, an effective sunscreen was one that blocked burning UVB rays and permitted socalled healthy UVA rays to go through the skin. The emphasis was on protection from the then-perceived harmful UVB rays. In fact, UVA rays were termed friendly and beneficial tanning rays. A tan was considered healthy and a...

The factors for melanoma UV radiation so can prevented reducing rays, them using sunscreen. use sunscreen...

BACKGROUND Sunscreens are being widely used to reduce exposure to harmful ultraviolet (UV) radiation. The fact that some sunscreens are photounstable has been known for many years. Since the UV-absorbing ingredients of sunscreens may be photounstable, especially in the long wavelength region, it is of great interest to determine their degradation during exposure to UV radiation. Our aim was to ...

BACKGROUND Sun exposure has positive and negative effects on health, yet little is known about the sun exposure behaviour of UK adolescents, including those more prone or less prone to sunburn.
