A few dermatologists use this scheme to classify skin types, although sometimes without fully understanding its correlation to sun exposure.Understanding of the biology of the melanin pigmentary system is based on research using light and electron microscopy.The Human Genome Project, along with advances in DNA and the mapping of the genes, should help dermatologists to further understand skin diseases and their treatment.
