  • Pigmentation Score from pigmented skin:
  • Pigmentation Score from normal skin:
  • Skin Hyperpigmentation Index (SHI):


Measurement of skin hyperpigmentation: upload the images of the hyperpigmented area (clinical or dermoscopic image) and reference image into the appropriate boxes and press the "Calculate" button.

Interpretation of the SHI results

1-2: light hyperpigmentation
2-3: medium hyperpigmentation
3-4: severe hyperpigmentation
4: maximum hyperpigmentation
