What is a common misconception about sunscreen?

A common misconception about sunscreen is that it is only needed on sunny days. This belief undermines the importance of sun protection in various weather conditions. UV rays, which can cause skin damage and increase the risk of skin cancer, are present even when it is cloudy or overcast. In fact, up to 80% of UV rays can penetrate through clouds and still have harmful effects on the skin. Therefore, it is essential to use sunscreen daily, regardless of the weather, to protect against both UVA and UVB rays year-round.

This understanding emphasizes the necessity of consistent sun protection habits, countering the belief that sunscreen is only for bright, sunny days, and helps to promote better skin health practices.
