There's a common misconception that you don't need SPF during the grey winter months, but it's so important to protect skin from UVA/UVB rays year-round.
When I started modeling, I was told to tan, but I always protected my face.
My mum taught me to always make sure you protect your skin with SPF. I always make sure I put my St. Tropez SPF on my face every morning, no matter the weather, before I go out of the house.
I know it's really square but I'm one of those people who piles on the factor 50 as soon as I'm outside.
I was fair-skinned in a country that's about the outdoors.
I wear sunglasses almost all the time outside - not because I think I'm really, really cool, but because of the rays.
Glossier is not about throwing out everything you're using. If you want to keep using your retinols, your SPFs, of course you should continue.
Even if it's snowing or raining, I'm always wearing sunscreen.
Seriously, I like to wear hats so I don't get super tan. You have to protect the face.
