To what number does the Fitzpatrick scale range for skin types?

The Fitzpatrick scale is a classification system that categorizes skin types based on their response to ultraviolet (UV) light exposure, particularly tanning and burning tendencies. It ranges from 1 to 6, with each type representing varying degrees of pigmentation and reaction to sun exposure. Type 1 indicates very light skin that always burns and never tans, while Type 6 refers to deep brown or black skin that rarely burns and tans easily.

Choosing 6 as the correct answer encompasses the full range of skin types described by the Fitzpatrick scale. Therefore, recognizing that the scale does not extend past this number reinforces understanding of its limitations and the importance of these classifications in dermatology and cosmetic treatments, including laser therapies.
