How often have you heard the reminder…don’t forget your sunscreen?  We typically follow this advice in summer, but remember sunscreen is still needed in winter too and even on cloudy days of summer.  Even though the sun is 93 million miles from Earth we still need sun protection.  The sun’s rays reaching Earth, and therefore us, include ultraviolet radiation which can damage skin, cause pre-mature skin aging and potentially increase risks of skin cancer.  Properly applied sunscreen can reduce all those harmful effects.  How does sunscreen do that?  Today’s Monday Molecule is a common sunscreen ingredient called oxybenzone.
