Fitzpatrick Phototype
Pronunciation: FITZ-pat-rik FOH-toh-typ
A classification of an individual's skin response to UV exposure based on the Fitzpatrick Scale, used in laser and energy-device treatment planning.
Full Definition
Fitzpatrick phototype is the individual classification assigned to a patient according to the Fitzpatrick Scale (I–VI), characterising their skin's typical response to ultraviolet radiation in terms of burning and tanning tendency. While the Fitzpatrick Scale itself already exists in the database, 'Fitzpatrick phototype' is the term used for a patient's specific assigned category within that scale and appears frequently in laser parameter documentation, clinical trials, and device safety labeling. Editors should note that 'phototype' and 'skin type' are not exactly interchangeable: 'phototype' is the technical classification, while 'skin type' is often used loosely in lay and marketing copy.
Usage
Usage note: Use 'Fitzpatrick phototype' in clinical and scientific copy; 'skin type' is acceptable only in patient-facing lay materials where technical precision is less critical.
In Context
- "Laser fluence settings were adjusted according to each participant's Fitzpatrick phototype prior to treatment." — Clinical trial protocol
- "The product insert used 'skin type' throughout; the editor flagged that the Fitzpatrick phototype classification was intended." — Regulatory document review
