The existence of the word “cosmeceuticals” is very much linked to the US FDA
definition of drugs and cosmetics in the 1938 FD&C Act. One can only speculate
as to why 60 years of scientific knowledge and research have been ignored by the
FDA in not revising the definition! The European Commission has been wiser
and its 1976 definition of cosmetics was modified in 1993 to acknowledge the fact
that everything put on the skin or hair may have a physiological effect (1). It puts
the responsibility on the industry to ascertain product safety and efficacy (claims
justification) (2).
