The Fitzpatrick scale groups typical response to ultraviolet light into six phototypes, I-VI, based on how readily skin burns and tans. It is a rough sun-reactivity tool—not a diagnosis, cancer-risk score, or promise of safe exposure time. Use repeated response history before skin color; if your history is mixed, choose conservative settings.
Fitzpatrick I-VI describes how skin typically burns and tans. It is a planning estimate—not a diagnosis or safe-time calculator.
What can change the tan window, SPF timing, or stop cue.
Fitzpatrick type is not a dermatology exam or cancer-risk diagnosis.
Phototype does not provide an exact safe exposure time.
Recent burns, medications, procedures, and photosensitivity can override baseline type.
Skin types V-VI are not immune to UV damage, eye effects, or skin cancer.
The quiz should ask about your real burn and tan response, then use type as an estimate for reminders and UV planning.
Match your usual burn-and-tan response, not a skin-color swatch. The six types summarize typical sun reactivity; they do not set a safe exposure time.
| Type | Typical response after unprotected sun | Planning note |
|---|---|---|
| Type I | Always burns, does not tan | Very sun-sensitive. Use the shortest exposure estimate. |
| Type II | Usually burns, tans with difficulty | Burn checks should happen early, even on moderate UV days. |
| Type III | Sometimes burns, tans gradually | A common middle band, but UV peaks can still burn fast. |
| Type IV | Rarely burns, tans easily | More tolerant, but not burn-proof or risk-free. |
| Type V | Very rarely burns, tans very easily | Lower burn tendency does not remove UV damage risk. |
| Type VI | Very unlikely to burn, deeply pigmented | Burns are less common, but eye and skin protection still matters. |
Choose the closest pattern from repeated past sun exposure. Do not choose from skin color alone. If two patterns fit, use “Not sure” and plan conservatively.

Medication, photosensitivity, recent procedures, and a recent burn can make your current sensitivity higher than this baseline. Ask a clinician when your reaction is unusual or uncertain.
The original Fitzpatrick classification and the NCBI I-VI reference describe sun-reactive skin types through typical burning and tanning behavior. Start with repeated history, use the closest broad pattern, and keep “uncertain” when your response varies. TanPilot uses the estimate only to make UV, SPF, and stop reminders more conservative.
Recall what usually happens after unprotected sun across more than one occasion. Do not deliberately expose skin to test a type.
Visible tone can overlap across phototypes. A color swatch, ethnicity, or one photograph cannot replace burn-and-tan history.
Mixed history should not be forced into a confident result. Use earlier warnings and clinician guidance when reactions are unusual.
Six broad self-reported buckets compress real biological variation. The scale can fit poorly across darker skin tones when color is treated as a shortcut or redness is harder to notice; types V-VI can still sustain UV damage. Photosensitizing medication, recent procedures, skin conditions, altitude, reflection, and a recent burn can make current sensitivity higher than baseline. A clinician should assess unexpected reactions or medical risk.
Short answers for the exact search intent, with the cautions that keep the plan usable.
Use your usual burn-and-tan response across repeated past sun exposure, then compare it with the I-VI reference. Do not deliberately expose skin to test yourself, and keep the result uncertain when two patterns fit.
The scale describes a broad baseline response, but a recent burn, medication, photosensitivity, a skin condition, or a procedure can raise current sensitivity. Treat those factors separately instead of assuming the baseline type protects you.
No. It is a rough phototype tool, not a diagnosis or complete risk score. Family history, previous burns, moles, immune status, medication, and other factors require separate medical assessment.
Not always. Six self-reported buckets can miss variation, especially when visible color substitutes for response history or redness is difficult to recognize. Types V-VI still need UV protection and should not be treated as immune to damage.
A rough phototype can help set more conservative early-warning and reminder defaults instead of using one rule for everyone. It cannot calculate a guaranteed safe tanning time.
Move from the UV number to tan timing, burn risk, skin type, and app setup.
