“…Of these, the Monte Carlo method stands out as the gold standard, which is widely used to calculate the propagation of light in complex tissue structures [18] , [19] , [20] . However, many existing MC algorithms are for simpler layered tissue models [21] , [22] , [23] , [24] . Most models resort to representing skin as a single or triple-layered homogeneous medium, a simplification that often overlooks the intricate optical characteristics of multi-layered skin structures [25] .…”
