Baumann Skin Types Baumann Skin Types The Baumann Skin Types system is a skin-type classification system defining 16 skin personalities. This classification system was developed in 2004 by University of Miami dermatology professor Leslie Baumann, to subdivide research participants into specific phenotypes. She assigns binary values to four characteristics, so defining sixteen "skin personalities", or "skin types". These have been used in genetic research aimed at identifying the genes that contribute to skin characteristics such as dryness, oiliness, aging, pigmentation and sensitivity. The a survey-based typing system combines these individual skin attributes into 16 personalities that allow researchers to improve their ability to
