Communicating with Patients about UV Safety and Vitamin D in Winter

(2025). Clinical Series. skinbetter science.

The article explains that while UVB radiation drops significantly in winter (limiting vitamin D production), UVA exposure remains constant year-round and continues to cause photoaging and DNA damage—even on cloudy or cold days. It clarifies that routine sunscreen use does not lead to vitamin D deficiency; instead, the safest and most effective way to maintain vitamin D levels is through diet and supplementation—not unprotected sun exposure.
