Full Definition
The term 'comedogenic' characterises ingredients or products that obstruct follicular openings, predisposing skin to blackheads and whiteheads. In cosmetic dermatology marketing and regulatory copy, 'non-comedogenic' is a widely used product claim, though it lacks a universally standardized testing methodology. Editors should note that the claim 'non-comedogenic' is unregulated in many jurisdictions and should not be presented as a guaranteed clinical outcome. The term should always be hyphenated in its negative form: 'non-comedogenic'.
Usage
Usage note: Always hyphenate the negative form: 'non-comedogenic'. Alert authors that this is a marketing claim, not a regulated designation.
