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 of, effect and/or absorbed:
“Considered physiologically, everything ugly weakens and saddens man. It reminds him of decay, danger, impotence; it actually reduces his strength. The effect of ugliness can be measured with a dynamometer. Whenever anyone feels depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with ugliness, they rise with beauty.”
—Friedrich Nietzsche (1844–1900)
“To see distinctly the machinery—the wheels and pinions—of any work of Art is, unquestionably, of itself, a pleasure, but one which we are able to enjoy only just in proportion as we do not enjoy the legitimate effect designed by the artist.”
—Edgar Allan Poe (1809–1849)
“One cannot long remain so absorbed in contemplation of emptiness without being increasingly attracted to it. In vain one bestows on it the name of infinity; this does not change its nature. When one feels such pleasure in non- existence, one’s inclination can be completely satisfied only by completely ceasing to exist.”
—Emile Durkheim (1858–1917)
