請問,我買了一瓶薇姿的隔離霜,它的Mexoryl SX, Terephthalylidene Dicamphor Sulfonic Acid 為3.960%,是否已達2/5的危險指數?謝謝

Mexoryl SX是较新的一种紫外线UVA防晒剂,皮肤吸收率低,获得了美国FDA的认可。不过,Mexoryl SX吸收紫外线的波段并未涵盖所有UVA波段,而且曝露在阳光下两小时即可分解40%,所以常常需要搭配其他防晒剂一起使用。

Mexoryls SX formulations always showed a higher protective potency than sunscreen without it even when the protection against erythema was similar (products with same SPF). Mexoryls SX formulations also prevented or significantly decreased to minimal, ferritin, tenascin and lysozyme expression induced by repeated UVA or SSR exposure. It also reduced the enhancement of collagenase 2 mRNA expression induced by SSR exposure. Finally PMLE study demonstrated that UVA protection was essential for the prevention of this photodermatose.
CONCLUSION:
Mexoryls SX formulated in sunscreens or daily use products have been shown to be an effective UV absorber, leading to an increased efficacy of these products against a large number of biological damage induced by UVA, SSR or sun exposure.
