4.4. Interactions with Invisible Light

Although our perception of skin appearance attributes takes place in the visible domain, several photobiological processes that affect these attributes are initiated by electromagnetic radiation in the ultraviolet and infrared domains. In this section, we examine these processes and discuss relevant implications not only for the simulation of skin appearance but also for the visual and noninvasive diagnosis of skin diseases.

4.4.1. Ultraviolet Domain

According to the CIE, ultraviolet (UV) radiation can be divided into three regions [27]: UV-A (ranging from 315 to 380 nm), UV-B (ranging from 280 to 315 nm), and UV-C (ranging from 100 to 280 nm). Ultraviolet light can induce a myriad of photobiological ...
