New Sunscreen Rules from the FDA has Sunscreen Manufacturers Scrambling to Meet Summer 2012 Deadline

The FDA has just released their update of sunscreen labeling and regulation, known as the Final Monograph. They will be using the Critical Wavelength® method to determine the degree of UVA protection. Only products with a Critical Wavelength® over 370nm will be allowed to be labeled as “Broad Spectrum”. The date for Sunscreen manufacturers to be compliant is June 18, 2012.  You don’t have to wait until next summer to protect your family from harmful UVA rays! LUCA® sunscreens already meet and exceed these new standards. We have been pushing the importance of Critical Wavelength® for years.

What is Critical Wavelength?

Critical Wavelength® (CW) is the most effective way to rate UVA protection. Solar radiation travels in waves. The wavelength corresponds to the solar energy of the wave. Solar radiation of 290nm to 400nm (the UVB-UVA range) is reproduced in a laboratory device designed to measure the amount of radiation absorbed by a sunscreen. Starting at the beginning of the UVB range (290nm), progressively higher wavelengths of light are aimed at the sunscreen. A protective absorption curve or “umbrella” is produced. The Critical Wavelength® defines how far this umbrella (actually 90% of the umbrella) extends into the UVA range. So for a Critical Wavelength® of 383nm, 90% of the sunscreen’s protective umbrella is between the beginning of the UVB range (290nm) to 383nm (see Graph below) The higher the number, the better. A sunscreen with a Critical Wavelength® over 370nm is considered by the FDA to provide Ultimate Broad Spectrum UVA/UVB protection.

NEW Trial Links Regular Sunscreen Usage to Prevent Melanoma

The use of sunscreens to prevent squamous and basal cell carcinomas is established, the role of sunscreens in preventing melanoma has been highly controversial. A new trial suggests that regular sunscreen use helps prevent melanoma. (J Clin Oncol. 2011;29:257-263.).
