Fitzpatrick scale

It was developed in 1975 by American dermatologist Thomas B. Fitzpatrick as a way to estimate the response of different types of skin to ultraviolet (UV) light.

The Fitzpatrick scale has been criticized for its Eurocentric bias and insufficient representation of global skin color diversity.

Studies demonstrate that European populations have the narrowest skin color variation, whereas groups categorized as 'brown' or 'black' exhibit a much wider range.

[10][11] The efficacy of the Fitzpatrick scale even among white-skinned individuals has been argued to be questionable,[9] since studies such as that on a Dutch student population[12] have found it inadequate for categorizing, challenging its appropriateness for investigating the relationship between sunburn tendency and tanning ability.

[9] The Fitzpatrick scale's Eurocentric orientation and its limitations in accurately representing global skin color diversity, along with similar biases in classifying other phenotypic traits, have been argued to require more inclusive and scientifically valid categorizations in dermatological and genetic research.
