Baumann Skin Typing System

The Baumann Skin Type Indicator, or Baumann Skin Typing System, is a skin type classification system created by dermatology professor Leslie Baumann. It was first unveiled in the book “The Skin Type Solution”, published in 2005.

The Baumann system is based around skin characteristics: Oily (O) versus Dry (D); Sensitive (S) versus Resistant (R); Pigmented (P) versus Nonpigmented (N); Wrinkled (W) versus Tight or Unwrinkled (T). When combined, these characteristics form 16 unique skin types.
