Key points

  • Multiple studies show that regular use of sunscreen can reduce the risk of developing skin cancer.
  • Sunscreen protects against harmful UV rays, which are a known cause of skin cancer.
  • The American Cancer Society and other health organizations recommend using sunscreen as part of sun protection strategies.

Explanation

Several sources from reputable health organizations such as the American Cancer Society (ACS) and the World Health Organization (WHO) consistently emphasize that wearing sunscreen is beneficial for skin health. These organizations state that sunscreen helps protect against harmful ultraviolet (UV) radiation, which can lead to skin cancer. They also note that while there have been isolated cases of sunscreen ingredients potentially causing irritation or other issues, these are not linked to an increased risk of skin cancer. In fact, studies suggest that regular use of sunscreen may reduce the incidence and severity of skin cancers.
