Effect of Topical Sunscreen and Effect of Absorbed Sunscreen
The direct DNA damage is reduced by sunscreen. This prevents sunburn. When the sunscreen is at the surface of the skin, it filters the UV-rays, which attenuates the intensity. Even when the sunscreen molecules have penetrated into the skin, they protect against the direct DNA damage, because the UV-light is absorbed by the sunscreen and not by the DNA.

Famous quotes containing the words effect and/or absorbed:
“Thinking is seeing.... Every human science is based on deduction, which is a slow process of seeing by which we work up from the effect to the cause; or, in a wider sense, all poetry like every work of art proceeds from a swift vision of things.”
—Honoré De Balzac (1799–1850)
“For my own part, I commonly attend more to nature than to man, but any affecting human event may blind our eyes to natural objects. I was so absorbed in him as to be surprised whenever I detected the routine of the natural world surviving still, or met persons going about their affairs indifferent.”
—Henry David Thoreau (1817–1862)
