With advances in sunscreen technology, the percentage of ingredient is no longer an adequate indication of the SPF conveyed by the product. Tests for SPF documentation are government mandated and supervised. The SPF number printed on the package indicates that the sunscreen showed a specific SPF when tested. Eclipse SPF50+ passed this testing with an SPF greater than 50 – hence the “50+” printed on the package. In recent years, the FDA (U.S. Food and Drug Administration) has not allowed the package label to indicate an SPF greater than 50, because SPF numbers greater than 50 are meaningless and give no further significant sun protection.
