The Beauty Brains | Why is Laura Mercier Tinted Moisturizer a poor sunscreen?
As you know, I love The Beauty Brains’ scientific approach to beauty. I know many of you are big fans of tinted moisturizer – particularly Laura Mercier. I apologize for being the bearer of bad news. If you are using your beloved Laura Mercier as your sunscreen, you may not be getting the protection you need.
“…Laura Mercier uses Octyl Methoxycinnamate and Menthyl Anthranilate in this moisturizer. Octyl Methoxycinnamate absorbs only UVB rays (280-320 nm) and Menthyl Anthranilate absorbs in the UVA region but only in the near UV-A (also known as UV II.) Ideally you want broad spectrum protection that includes the far end of the UVA spectrum (known as UVA-I) and for that you need an ingredient like Avobenzone or a blocker like zinc oxide.”
If you are looking for solid UVA protection, go for products with Avobenzone or zinc oxide.
