Fitzpatrick Scale
Pronunciation: FITZ-pat-rik SKAYL
A six-point classification system that categorises human skin types by their response to ultraviolet radiation, used widely in aesthetic dermatology to assess treatment suitability and risk.
Full Definition
The Fitzpatrick Scale, developed by dermatologist Thomas B. Fitzpatrick in 1975, classifies skin into six phototypes (I–VI) based on an individual's complexion and their reported reaction to sun exposure, ranging from Type I (always burns, never tans) to Type VI (deeply pigmented, never burns). In aesthetic dermatology, it is a critical reference tool for determining patient candidacy for laser treatments, chemical peels, and light-based therapies, as higher Fitzpatrick types carry greater risk of post-inflammatory hyperpigmentation. Editors must render the scale name with an initial capital 'F' as it is an eponymous classification. Roman numerals (I–VI) are the conventional notation, not Arabic numerals. The term is sometimes incorrectly called the 'Fitzpatrick Skin Type Scale' or abbreviated in inconsistent ways.
Usage
Usage note: Always capitalise 'Fitzpatrick' as an eponym. Use Roman numerals I–VI for skin types. Avoid 'Fitzpatrick score' as the system is a classification, not a scored instrument.
