There are only a few qualitatively limited methods that allow its quantification. Previous techniques to develop a reliable scientific approach to quantification have failed due to the lack of standardized conditions including differences in lighting, distances and equipment. A newly developed measuring method, the \u201cskin hyperpigmentation index\u201d, enables a fully automated and standardized quantification of skin hyperpigmentation with dermatoscopic images. The skin hyperpigmentation index defines the ratio of two scores, namely hyperpigmented skin of the affected area and normal sun protected skin from the same patient. This results in a range from 1 (no pigmentation) to 4 (maximum pigmentation). For a practical evaluation of the score, a free skin hyperpigmentation index calculator can be used online, which is accessible to all practitioners ( https:\/\/shi.skinimageanalysis.com\/ ). The skin hyperpigmentation index is a fully automated method for the quantitative assessment of skin pigmentation which can easily be applied to any skin type with any type of hyperpigmentation. This allows a simple, fast, and standardized quantification of skin hyperpigmentation and is useful for monitoring the progress and planning of whitening therapy.<\/jats:p>","DOI":"10.1177\/0268355520941359","type":"journal-article","created":{"date-parts":[[2020,7,27]],"date-time":"2020-07-27T02:24:15Z","timestamp":1595816655000},"page":"833-835","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["The skin hyperpigmentation index: An objective method of measuring the intensity of hyperpigmentation after sclerotherapy"],"prefix":"10.1177","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1285-302X","authenticated-orcid":false,"given":"Simon","family":"Bossart","sequence":"first","affiliation":[{"name":"Department of Dermatology, Inselspital, Bern University Hospital, University of Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4349-5747","authenticated-orcid":false,"given":"Torsten","family":"Willenberg","sequence":"additional","affiliation":[{"name":"Gef\u00e4sszentrum Bern, VASC, Lindehofspital Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert-Adrien","family":"Ramelet","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Inselspital, Bern University Hospital, University of Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simone","family":"Cazzaniga","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Inselspital, Bern University Hospital, University of Bern, Switzerland"},{"name":"Centro Studi GISED, Bergamo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert E","family":"Hunger","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Inselspital, Bern University Hospital, University of Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6466-2199","authenticated-orcid":false,"given":"S Morteza","family":"Seyed Jafari","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Inselspital, Bern University Hospital, University of Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,7,26]]},"reference":[{"key":"bibr1-0268355520941359","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.16312."},{"key":"bibr2-0268355520941359","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2007.08.007"},{"key":"bibr3-0268355520941359","unstructured":"Ramelet A-A, Perrin M, Kern P, et\u00a0al.
