What does ingredients being "biologically active" mean? From Wikipedia


  Cosmeceuticals refers to the combination of cosmetics and
  pharmaceuticals. Cosmeceuticals are cosmetic products with
  biologically active ingredients purporting to have medical or
  drug-like benefits.


I was wondering what  ingredients being "biologically active" means? 

In cosmetics that are not cosmeceuticals, are their ingredients not "biologically active"?
Chemists usually marks as biologically active compounds, that have clear effect on living being in small amounts. For example, methane is not biologically active, but potassium cyanide clearly is. Of course, the borderline is quite blurry and can move if context changes.
