Brian Diffey, BSc, AKC, PhD, DSc is Emeritus Professor of Photobiology in Dermatological Sciences, Institute of Cellular Medicine at the University of Newcastle, UK.During his career in the NHS, he established an internationally-respected research program in skin photobiology, particularly in the measurement of personal sun exposure; its effects in normal and diseased human skin; and ways to minimize excessive exposure, especially through the use of topical sunscreens.He has advised a number of bodies on sun exposure and skin health including the World Health Organization, Department of Health, and the Cancer Research UK SunSmart program, as well as patient support groups concerned with sun-related diseases such as melanoma, vitiligo and xeroderma pigmentosum.He invented both the UVA Star Rating for sunscreens in conjunction with Boots in the UK, and the Critical Wavelength adopted by the Food &amp; Drug Administration in the USA as the sole measure of broad spectrum protection.In 1999 he was awarded the Medal of the Society of Cosmetic Scientists for his contributions to suncare, and in 2011 was honoured at the International Sun Protection Conference for significant innovation in the field of photoprotection.He is an honorary member of the British Association of Dermatologists, the Swedish Society for Dermatology and Venereology, and the European Society for Photodermatology.

Sunscreens and sunprotection with Dr. Brian Diffey

By now I’m sure you’ve heard some of the hype regarding a  recent study on sunscreen that was released last week in JAMA. With coverage usually using bold titles like “SUNSCREENS ABSORB ALL THE WAY INTO YOUR BLOOD”, there’s no shortage of bad journalism on this study. In response to all of this, I decided to reach out to Dr. Brian Diffey from Newcastle University - a prolific sun care researcher who has published more than 450 papers as well as a recent book, Sun Protection: a risk management approach. He also invented both the UVA Star Rating for sunscreens in conjunction with Boots in the UK, and the Critical Wavelength adopted by the Food &amp; Drug Administration in the USA as the sole measure of broad-spectrum protection. In our conversation, we talked about how sun protection works, SPF, UVA &amp; UVB rays, the current understanding regarding environmental and health impacts, and of course, what this recent study actually said and take-homes from these results. I was so grateful to have the opportunity to speak with Dr. Diffey; an information packed conversation about sun protection.
