Fitzpatrick Skin Phototype UV Response

Classify skin type using Fitzpatrick scale (I-VI) based on constitutive pigmentation and UV tanning response to guide phototherapy dosing, skin cancer risk counseling, and laser parameter selection.

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

Classify skin type using Fitzpatrick scale (I-VI) based on constitutive pigmentation and UV tanning response to guide phototherapy dosing, skin cancer risk counseling, and laser parameter selection

Each component has a specific meaning:

  • Fitzpatrick scale based on constitutive pigmentation — The fitzpatrick scale based on constitutive pigmentation recorded for the scenario being assessed.
  • UV tanning response — The uv tanning response recorded for the scenario being assessed.

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

How to Use

Enter the Fitzpatrick scale based on constitutive pigmentation, UV tanning response for the scenario you are assessing. Classify skin type using Fitzpatrick scale (I-VI) based on constitutive pigmentation and UV tanning response to guide phototherapy dosing, skin cancer risk counseling, and laser parameter selection. Use the fitzpatrick phototype result to inform your calculation.
