AB SUMMARY  POINTSWhat’s  Important?Antioxidants  protect  against  the  ravages  of  free  radicals  by  reducing  and  neutralizing  them.Antioxidants  may  be  particularly  useful  in  UVA-induced  skin  alterations  that  are  believed  to  be  determined,  in  large  part,  by  oxidative  processes.Topical  antioxidants  are  currently  marketed  for  the  prevention  of  aging  and  UV-mediated  skin  damage  as  well  as  the  treatment  of  wrinkles  and  erythema  due  to  inflammation,  such  as  that  induced  by  laser  resurfacing.The  free  radical  theory  of  aging  explains  why  antioxidants  are  thought  to  prevent  wrinkles,  but  this  theory  does  not  justify  the  use  of  antioxidants  to  treat  wrinkles  that  are  already  present.What’s  New?New  antioxidants  are  being  introduced  into  the  market  frequently.Using  combinations  of  antioxidant  types  is  preferred  rather  than  one  antioxidant.Antioxidants  should  be  included  in  diet,  beverages,  and  supplements  in  addition  to  topical  skincare  products.What’s  Coming?New  methods  are  needed  to  quantify  antioxidant  strength  so  that  efficacy  between  types  can  be  compared.  Current  antioxidant  quantitative  measurements  such  as  the  ORAC  value  pertain  to  foods,  not  topical  products.Antioxidants  are  being  evaluated  to  protect  mitochondria  and  other  cellular  components.
