Sunscreen can give a false sense of security by providing a physical barrier to the sun’s harmful UV rays, which can make people believe they are fully protected. This may lead individuals to spend more time in the sun than they should, engage in riskier behaviors like not seeking shade or wearing protective clothing, and not reapplying sunscreen as recommended. Overreliance on sunscreen can result in inadequate sun protection and an increased risk of sunburn and skin damage.
