☀️ Melanoma & Hyperpigmentation UV Risk Calculator

Estimate your lifetime UV‑related skin risk profile based on sensitivity, sunburn history, tanning habits, and family history. Use it to guide smarter sun‑protection—not as a diagnosis.

Melanoma vs. Hyperpigmentation

Melanoma is a dangerous skin cancer that develops from pigment‑producing cells. Hyperpigmentation refers to benign dark spots or patches (like sun spots or melasma) caused by excess pigment. Both are influenced by UV exposure, but melanoma is life‑threatening and requires early detection, while hyperpigmentation mainly affects appearance and may signal chronic sun damage.

This calculator focuses on patterns that increase cumulative UV damage over a lifetime. High scores don’t mean you will get melanoma or severe hyperpigmentation—but they do mean your UV exposure and protection habits deserve attention.

Warning Signs That Need a Professional Check

  • Moles or spots that are Asymmetric, have irregular Borders, multiple Colors, big Diameter, or are Evolving (the ABCDE rule).
  • New dark patches that grow quickly or change in color or shape.
  • Any spot that itches, bleeds, or doesn’t heal.

If you see any of these, book a skin check with a dermatologist as soon as possible.

Frequently Asked Questions

Can an online calculator tell me if I have skin cancer?

No. Only a trained clinician using a full skin exam and, if needed, a biopsy can diagnose melanoma or other skin cancers. This tool is designed to highlight patterns of UV exposure and family history that increase risk—not to detect cancer.

I have darker skin. Do I still need to worry about UV damage?

Yes. Darker skin has more natural UV protection against sunburn, but melanoma can still occur, often diagnosed later. Darker skin is also more prone to certain types of hyperpigmentation. Consistent SPF, shade, and regular skin checks are still important.
