Sunscreens protect against sunburn, but there is no evidence that they protect against basal cell carcinoma or melanoma. Problems lie in the behavior of individuals who use sunscreens to stay out longer in the sun than they otherwise would. Vitamin D inhibition is, at this stage, unlikely due to insufficient use by individuals. Safety of sunscreens is a concern, and sunscreen companies have emotionally and inaccurately promoted the use of sunscreens.
防晒霜可以预防晒伤，但目前没有证据表明它们可以预防基底细胞癌或黑色素瘤。问题在于使用防晒霜的人的行为，他们会因此比平时在太阳下待得更久。在现阶段，由于个人使用不足，维生素 D 抑制不太可能发生。防晒霜的安全性是一个令人关注的问题，防晒霜公司在情感上和不准确地推广了防晒霜的使用。
