FSP
Also written as: FSP — Fitzpatrick Skin Phototype
Abbreviation for Fitzpatrick Skin Phototype, the six-category classification of skin response to UV radiation.
Full Definition
FSP is the standard abbreviation for Fitzpatrick Skin Phototype, used widely in dermatological literature, photobiology research, and cosmetic dermatology publications. It condenses the full eponymous classification name in tables, figures, and repeat references. Editors should define FSP on first use in a document and ensure consistency with Roman numeral notation (FSP I through FSP VI). The abbreviation should not be confused with other dermatology acronyms such as SPF (Sun Protection Factor).
Usage
Usage note: Always spell out on first use as 'Fitzpatrick Skin Phototype (FSP).' Do not confuse with SPF, which refers to sun protection factor in sunscreen labelling.
