P&G Uncovers Gaps in Sunscreen Protection

New research conducted by Procter & Gamble Beauty suggests two main reasons why some sunscreens fail to provide adequate protection: sunscreens have a “gap” in UVA coverage and most people apply sunscreen incorrectly. The research, presented at the 2004 American Academy of Dermatology meeting, was based on an analysis of 188 currently marketed sunscreen products.

Findings revealed that while 82% of current sunscreen claim UVA protection, only 56% have long wavelength UVA-I filters. Also, most do not protect against the full spectrum of UVA/UVB radiation in sunlight, from 290-400 nanometers. Unfortunately there are no standardized tests to measure sunscreens against the full spectrum.

“Consumers think they are protected, but unknowingly experiencing sun damage,” said J F. Nash, Ph.D, principle scientist at P&G Beauty. P&G advocated to the Food and Drug Administration for the use of Critical Wavelength measures and consistent and accurate label identification of qualified broad-spectrum sunscreens.

A national survey also showed that 75% of dermatologists believe patient compliance is the most important factor in achieving sunscreen effectiveness. Many consumers assume SPF 30 has twice the effectiveness of SPF 15, however researchers found SPF 15 may be more efficacious due to the lighter formulations, as opposed to heavier, stickier high SPF lotions that are used sparingly.
