I saw this in an online magazine and thought I would post it here ...

Australian pharmaceutical company Hamilton Laboratories has launched the only sunscreen that has been demonstrated through scientific testing to make an immune suppression claim.

We all know about the well-known effects of UV radiation such as sunburn, premature ageing and skin cancer, but according to research ultraviolet radiation has an impact on the body's immune system.

Hamilton Optimal™ Enhanced Protection Sunscreen is the result of more than a decade of research and development in conjunction with Flinders University of South Australia, Flinders Technologies Pty Ltd and the University of Sydney, to develop and release a sunscreen which demonstrated a significant reduction of immunosuppression caused by exposure to UV radiation.

Independent research demonstrated that excessive exposure to UV radiation alters the immune system and this in turn can reduce the body's ability to protect itself against skin cancer.

Hamilton Optimal™ Sunscreen works by reducing some of the effects of UV induced immunosuppression. Hamilton Optimal™ Sunscreen provides:
* More than 10 years of research, development and strict testing
* Very High Broad Spectrum Protection Sunscreen
* 4 hours water resistance
* Light and non-greasy lotion
* Easy application
* Free from potential irritants such as padimate O, PABA and oxybenzone

Hamilton Optimal™ Enhanced Protection Sunscreen is available only at pharmacies.

Also, apparently the sunscreen measures as SPF 80+ (though here in Australia we don't have anything marked as higher than 30+. Usually products like this say they offer 'very high protection', like the Megan Gale Invisible Zinc - which works a treat at sun protection at the beach, just not very nice to wear.)
