Experts Stress Sunscreen Use to Reduce Rising U.S. Skin Cancer Cases

Experts emphasize the importance of sunscreen for all skin tones, highlighting that darker skin, despite higher melanin, still requires protection against sunburn, hyperpigmentation, and skin cancer risks, including melanoma. Dermatologists recommend using sunscreen with at least SPF 30 and reapplying every two hours, especially after swimming or sweating, noting many people apply insufficient amounts. UVA and UVB rays can cause DNA damage, leading to premature aging and serious skin cancers, making consistent sun protection crucial. Water-resistant and sweat-resistant sunscreens are particularly beneficial for those active outdoors or spending time in water. Additional protective measures include wearing long-sleeved clothing, hats, and avoiding peak sun hours. Public health messages continue to stress vigilance in monitoring skin changes such as new or bleeding moles, urging prompt medical consultation.
