Fitzpatrick Skin Phototype Classification

Classifies skin phototype (I-VI) based on genetic background, sun exposure reaction history, and tanning ability to guide UV therapy dosing (NB-UVB MED), laser parameter selection, and melanoma/NMSC risk counseling.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Classifies skin phototype (I-VI) based on genetic background, sun exposure reaction history, and tanning ability to guide UV therapy dosing (NB-UVB MED), laser parameter selection, and melanoma/NMSC risk counseling

Each component has a specific meaning:

  • Genetic background — The genetic background recorded for the scenario being assessed.
  • Sun exposure reaction history — The sun exposure reaction history recorded for the scenario being assessed.
  • Tanning ability — The tanning ability recorded for the scenario being assessed.

Note: Interpret the fitzpatrick phototype result against the thresholds and context described above.

How to Use

Enter the genetic background, sun exposure reaction history, tanning ability for the scenario you are assessing. Classifies skin phototype (I-VI) based on genetic background, sun exposure reaction history, and tanning ability to guide UV therapy dosing (NB-UVB MED), laser parameter selection, and melanoma/NMSC risk counseling. Use the fitzpatrick phototype result to inform your calculation.
