The Seal of Recommendation for Safe and Effective Sun Protection is recognized world wide.

The Seal of Recommendation is granted only to products that meet the Skin Cancer Foundation's criteria for safe and effective sun protection, when used as directed. The Seal of Recommendation is awarded to individual sun protection products, not to brands.
