Potential of herbs in skin protection from ultraviolet radiation

Protection against solar ultraviolet radiation in childhood.

In the last decade, awareness of the harmful effects of solar ultraviolet radiation has increased. Modern lifestyles, outdoor occupations, sports and other activities make total sun avoidance impossible. Children spend more time outdoors than adults and there is compelling evidence that childhood is a particularly vulnerable time for the photocarcinogenic effects of the sun. Sun exposure among ...

Photoprotection beyond ultraviolet radiation--effective sun protection has to include protection against infrared A radiation-induced skin damage.

Solar radiation is well known to damage human skin, for example by causing premature skin ageing (i.e. photoageing). We have recently learned that this damage does not result from ultraviolet (UV) radiation alone, but also from longer wavelengths, in particular near-infrared radiation (IRA radiation, 760-1,440 nm). IRA radiation accounts for more than one third of the solar energy that reaches ...

Chemoprevention of ultraviolet radiation-induced skin cancer.

The use of chemical and physical sunscreening agents has increased dramatically during the last two to three decades as an effective means of preventing sunbum. The use of high sunprotection factor sunscreens has also been widely promoted for the prevention of skin cancer, including melanoma. Whereas sunscreens are undoubtedly effective in preventing sunbum, their efficacy in preventing skin ca...
