Tanning without sunscreen causes more acute skin damage, erythema, and long-term cancer risk from ultraviolet radiation compared to tanning with equivalent protection. Scientific evidence consistently shows that sunscreens protect against these harmful UV effects.
The claim asserts that tanning without sunscreen for 10 minutes is healthier than with sunscreen. Dermatological science demonstrates that unprotected UV exposure causes immediate erythema (sunburn) and long-term risks such as skin cancer, whereas sunscreen effectively attenuates these hazards. None of the retrieved papers support the idea that going without sunscreen is healthier; rather, papers like [0], [6], and [10] highlight the protective benefits of sunscreens against UV-induced damage.
