Step 1 : Introduction to the question " Which one of the following types of solar radiation does sunscreen protect the skin from? "

Natural sunlight contains, among other things, ultraviolet (UV) photons. These photons are shorter in wavelength and higher in energy than visible light. Because they fall outside the visible spectrum, the human eye cannot perceive them. When it comes to sun exposure, however, what you can't see will hurt you. When these high-energy photons strike your skin, they generate free radicals and can also directly damage your DNA. Over the short term, this UV-induced damage can produce a painful burn; over the long term it causes premature aging of the skin, as well as millions of new cases of skin cancer each year. A sunscreen product acts like a very thin bulletproof vest, stopping the UV photons before they can reach the skin and inflict damage. It contains organic sunscreen molecules that absorb UV and inorganic pigments that absorb, scatter and reflect UV.
