Ganda rakajairika rine simba rekupinza chiedza kuti ridzivirire nhengo nematishu mumuviri kubva mukukuvadzwa nechiedza. Kugona kwechiedza kupinda mumatishu evanhu kwakabatana zvikuru nehurefu hwaro hwewavelength uye chimiro chematishu eganda. Kazhinji, kana wavelength iri pfupi, ndipo panopinda ganda zvishoma. Tishu yeganda inopinza chiedza nekusarudza kwakajeka. Semuenzaniso, makeratinocytes ari mu stratum corneum anogona kutora huwandu hwakawanda hwemwaranzi ye ultraviolet ye short-wave (wavelength ndeye 180 ~ 280nm), uye masero e spinous ari mu spinous layer ne melanocytes ari mu basal layer anotora mwaranzi ye ultraviolet ye long-wave (wavelength ndeye 320 nm ~ 400nm). Tishu yeganda inotora ma wavelength akasiyana echiedza zvakasiyana, uye mwaranzi ye ultraviolet yakawanda inotorwa ne epidermis. Sezvo wavelength ichiwedzera, mwero wekupinda kwechiedza unochinjawo. Mwaranzi ye infrared iri pedyo nemuchina we red light inopinda muzvikamu zvakadzika zveganda, asi inotorwa neganda. Iyo infrared ye "long-wave" (wavelength i15~400μm) inopinda zvisina kunaka, uye yakawanda yacho inonyudzwa ne "epidermis".
Zviri pamusoro apa ndizvo zvinorehwa nedzidziso yekutimuchina wekuongorora gandainogona kushandiswa kuona matambudziko eruvara rweganda.muchina wekuongorora gandainoshandisa ma spectra akasiyana (RGB, Cross-polarized light, Parallel-polarized light, UV light uye Wood's light) kugadzira ma wavelength akasiyana kuti ione matambudziko eganda kubva pamusoro kusvika pakadzika, saka makwinya, tsinga dzemusana, maburi makuru, mavanga epamusoro, mavanga akadzika, pigmentation, pigmentation, kuzvimba, porphyrins nezvimwe zvinetso zveganda zvinogona kuonekwa ne skin analyzer.
