Explain the 'Pros' and 'Cons' of Using Sunscreens

Question

Examlex · Accepted Answer

The Answer is Certainly one of the well-known benefits of using sunscreen is for protection against the harmful UV rays. Wearing a sunscreen with a sun protection factor (SPF) of 15 can prevent burning and protect against skin cancers. In contrast, one negative aspect of sunscreens is that they can inhibit the synthesis of vitamin D. In fact, a sunscreen with a SPF of 8 will reduce vitamin D production in the skin by 95%, while an SPF 15 sunscreen reduces synthesis by 98%. Unfortunately, the best times of the day for vitamin D synthesis are when exposure to ultraviolet rays may be discouraged to prevent skin cancers. The current recommendation is to expose (with no sunscreen) your arms and legs or your hands, arms, and face to sunlight between 10 a.m. and 3 p.m. for about 5 to 10 minutes, 2 or 3 times a week, with longer times needed for individuals of dark skin pigmentation.
