對於皮膚健康而言，這是一次重大勝利，美國食品藥物管理局（FDA）於2026年6月正式批准了苯基二苯並咪唑四磺酸二鈉，亦稱為Tinosorb S，作為一種新的防曬活性成分。
In a major victory for skin health, the U.S.
這是美國食品藥物管理局近30年來首次更新其非處方（OTC）防曬劑專論。
Food and Drug Administration (FDA) officially approved bemotrizinol, also known as Tinosorb S, as a new active sunscreen ingredient in June 2026.
苯基二苯並咪唑四磺酸二鈉是一種強效、廣譜的紫外線過濾劑，能獨自有效地阻擋UVA和UVB射線。
This is the first time in nearly 30 years that the FDA has updated its over-the-counter sunscreen monograph.
它已被歸類為對成人及六個月以上的兒童「一般公認安全且有效」（GRASE）。
Bemotrizinol is a powerful, broad-spectrum UV filter capable of blocking both UVA and UVB rays efficiently on its own.
苯基二苯並咪唑四磺酸二鈉最令人興奮的特性之一是其光穩定性，這意味著它在陽光下不易分解，能提供更持久的防護。
It has been classified as Generally Recognized as Safe and Effective (GRASE) for adults and children as young as six months.
此外，皮膚科醫生稱讚其化妝品優雅度，因為它能創造出不油膩、透明的配方，使用感極佳。
One of the most exciting aspects of bemotrizinol is its photostability, meaning it resists breaking down under sunlight, offering longer-lasting protection.
儘管該成分在全球已使用數十年，但得益於《CARES法案》，其在美國的批准程序得以加速。
Additionally, dermatologists praise its cosmetic elegance, as it creates non-greasy, transparent formulas that are pleasant to wear.
透過彌補技術上長期存在的缺口，此次批准有望讓民眾的日常防曬變得更簡單、更有效，並最終藉由更好、更規律的習慣來對抗日益攀升的皮膚癌發生率。
While this ingredient has been used globally for decades, the U.S. approval was accelerated thanks to the CARES Act.
