Sunscreen products are among the most important ways for skin protection against sunburn, early skin aging and skin cancer. Due to existing wide variation of sunscreens, it is necessary to assure their protection ability against the sun damage. Performance assessment of sunscreen products against UVA is expressed by sun UVA protection factor (UVA-PF). Because currently these factors are determi...

Skin cancer is increasing, and prevention programs are essential. This study evaluated the impact of a skin cancer prevention program on sun-protection habits and swimming pool environments. The intervention included staff training; sun-safety lessons; interactive activities; providing sunscreen, shade, and signage; and promoting sun-safe environments. A randomized trial at 28 swimming pools in...

The usage of sunscreens has grown dramatically worldwide over the past decade. Current data suggest that a regimen of sun protection that includes protective clothing, avoiding midday sun, and regular use of broad-spectrum high SPF sunscreen (such as practiced in Australia [19]) seems to be reducing melanoma incidence rates. This is the current recommendation of the American Academy of Dermatol...

Tanning is the increase in skin pigmentmelanin; it causes the change in color of our skin. Excessive tanning causes skin damage. It is overexposure to the UV rays from the sun. The supreme cause of skin cancer is believed to be the over exposure to the solar radiation which is the medley of ultra-violet radiation (UVA, UVB, and UVC), and visible light. UVB is the stronger component amongst the ...

Titanium oxide (TiO2) nanoparticles are added to sunscreens as they have broad absorbance across the whole UV spectrum. Although photostable, TiO2 nanoparticles can de-excite via surface states giving rise to reactive oxygen species (ROS) formation within the sunscreen formulation. An increased ROS load can degrade organic components within the sunscreen, such as UV absorbers or anti-oxidants, ...
