Summary
How much sun do you actually need for vitamin D? Does SPF block vitamin D production? And can low vitamin D cause hair loss? In this episode of After Hours Skin Clinic, consultant dermatologists Dr Emma Craythorne and Dr Ellie Rashid explore the science behind vitamin D, its role in skin and overall health, and the truth about sun exposure. From medical guidance to common myths about SPF and vitamin D deficiency, they break down what the evidence actually says, and what it means for your daily routine. You’ll learn: How vitamin D is produced in the skin (and why UVB matters) Why most people in the UK need supplements in winter How much sun exposure is enough and why more isn’t better Whether sunscreen affects vitamin D levels The best dietary sources of vitamin D Safe supplementation and dosing Why sunbeds are not a safe option The link between vitamin D deficiency and hair loss Emerging research on vitamin D, inflammation, and immune health Emma and Ellie also discuss large-scale clinical studies exploring vitamin D’s potential role in reducing autoimmune disease risk and improving health outcomes. 💡 Key takeaway: You don’t need prolonged sun exposure for vitamin D and supplements are often the safest and most effective option.
