Frequently asked questions
Is tocopherol comedogenic?
Tocopherol scored 0 to 3 out of 5 for comedogenicity in Fulton's 1989 rabbit-ear study, where 0 means no clogging and 5 means severe. That is a moderate rating. The test used the raw ingredient, so a finished product may behave differently.
What does tocopherol do in skincare?
In short: vitamin E that protects skin and keeps oils fresh. In formulas it is used for antioxidant, masking and skin conditioning.
What else is tocopherol called on ingredient labels?
On ingredient lists, tocopherol can also appear as Vitamin e, Alpha-tocopherol, D-alpha-tocopherol or Dl-alpha-tocopherol.
