FDA對此新規定接受大家建議的日期,
延期到12/26/2007會有幾個月緩衝期讓廠商修改標仿及做相關試驗,
新規定內容如下:
With the proposed UVA rating system
One star will represent low UVA protection
Two stars, medium protection
Three stars, high protection
Four stars, the highest UVA protection available in an over-the-counter (OTC) sunscreen product.
If a sunscreen product does not rate at least one star, FDA is proposing that its labeling bear a "no UVA protection" marking on the front label, near the SPF value.
衛生署,目前仍使用三級分類:
為防禦UVA的能力，以遮斷UVA程度分成三級：
PA +：平時保護敏感性肌膚用，遮斷輕度至中度之UVA。
PA ++：提供正常肌膚較佳防護，或遮斷中度的UVA。
PA +++：提供正常肌膚更強的防護，或可高度遮斷紫外光UVA。
