Cosmeceutical

Cosmeceutical — a marketing term for a cosmetic product that is claimed to offer skin benefits associated with active, biologically functional ingredients, positioned somewhere between a standard cosmetic and a pharmaceutical drug. The word has no formal legal definition in many regions, so products described this way are still regulated as cosmetics rather than as medicines.

Key points

  • The term blends cosmetic and pharmaceutical but is not an officially recognized regulatory category in the United States or the European Union.
  • Products marketed as cosmeceuticals often feature ingredients like retinoids, vitamin C, peptides, or antioxidants.
  • Because they are regulated as cosmetics, such products cannot legally claim to treat or alter the body's structure or function like a drug.
  • Ingredient effectiveness varies and depends on factors such as concentration, formulation, and stability.
  • The label is primarily a marketing distinction rather than a guarantee of clinical performance.

Frequently asked

Is a cosmeceutical a drug?

No; in most jurisdictions cosmeceutical is a marketing term and these products are legally regulated as cosmetics, not as drugs, so they cannot make drug-level treatment claims.

Are cosmeceuticals more effective than regular cosmetics?

Not automatically; effectiveness depends on the specific ingredients, their concentration, and how the product is formulated, rather than on the cosmeceutical label itself.
