Do you need sunscreen every day ... even when it’s cloudy or you’re indoors? In this episode, Consultant Dermatologists Dr Emma Craythorne and Dr Ellie Rashid explain the science behind daily SPF use and why consistent sunscreen application is one of the most effective ways to protect long-term skin health. They break down how ultraviolet radiation affects the skin, including UVA, UVB, and visible light, and why damage accumulates over time, even without sunburn.
