The development of the 256 unique skin types by Dr Ghotra is a narrative of meticulous research and technological integration. To better understand this, let's follow the journey of an arbitrary patient, Sarah, as she navigates through the process. Sarah begins her journey with a superficial skin analysis, which evaluates the fundamental aspects of her skin: Dehydration (D), Inflammation (I), Pigmentation (P), and Wrinkle Formation (W). This analysis categorizes Sarah's skin as Dry (D), Sensitive (S), Pigmented (P), and Wrinkle-Prone (W).
