Sunscreen should be part of your daily skincare routine, even on cloudy days – and throughout the winter. That’s because whenever you’re outside, you’re exposed to UV radiation, which can penetrate through cloud (and UVA rays can also penetrate glass). Then there’s blue light (also known as High Energy Visible Light/HEVL), which is emitted not just from the sun, but from our digital devices too. Keep your skin protected with a daily sunscreen. Choose broad-spectrum formulations, apply liberally, and reapply often.
