The findings underscore the importance of using sunscreen to protect against harmful UV rays, which can cause sunburn, premature aging, and skin cancer. Consumers should be aware that not all sunscreens perform equally, and some may not meet their labeled SPF claims. Improper application, especially with sprays, can reduce effectiveness and increase risks. Water-resistant sunscreens are particularly important for activities involving water or heavy sweating, but they still require reapplication every two hours. The risks of inhaling spray sunscreens and the potential for uneven coverage highlight the need for careful application.
