Everyone knows wearing sunscreen in the summer is important, but many forget that even in the winter our skin is exposed to harmful UVA and UVB rays. If you’re like me you think, “but I work in an office and am inside all day, why wear sunscreen?” Well, Dr. Marsha Gordon, St. Ives Consulting Dermatologist, has thankfully made me rethink this notion. Dr. Gordon says that although “the amount of ultraviolet radiation produced by ordinary fluorescent lighting is very small, in winter we are still exposed to ultraviolet rays from the sun. We are exposed during our commutes because UVA penetrates window glass, in our offices and homes if they are sunny and we are exposed even more if we enjoy snow sports because of the reflection added by the snow.” She emphasizes that this cumulative UV exposure is what causes photo aging (exactly what we don’t want!), so it’s important to protect our skin (face, neck, chest, anything exposed) everyday. via SPF in Winter Too, Your Skin Will Thank You! – Beauty News NYC – The First Online Beauty Magazine.
