The FDA has approved a sunscreen(日焼け止めクリーム)that blocks the type of ultraviolet(紫外線の)radiation linked to some cancers. Anthelios SX contains ecamsule, a compound that helps protect against UVA(紫外線A)radiation, which is believed to be linked to malignant melanoma(黒色腫). The sunscreen ingredients currently sold in the US block UVB(紫外線B)rays, which are mainly responsible for causing sunburns. Anthelios SX is made by L'Oreal and will be distributed in the US by LaRoche-Posay.
