The Baumann Skin Types system: personalized by design.
Dr. Baumann created a structured method for classifying skin across four independent dimensions, creating 16 distinct skin types. This system provides the foundation for truly personalized skincare.
Unlike traditional approaches that rely on broad labels such as "dry," "oily," or "sensitive," the Baumann Skin Types system evaluates multiple dimensions of skin behavior at the same time.
16 distinct skin types
Precise classification for product selection, ingredient strategy & regimen design
Dehydration
Dry or Oily
Evaluates sebum production, hydration needs, and barrier behavior.
Sensitivity / Inflammation
Sensitive or Resistant
Assesses reactivity, redness, inflammation, stinging, acne, rosacea tendencies.
Pigmentation
Pigmented or Non-Pigmented
Evaluates melanin activity, discoloration risk, uneven tone, and pigmentation concerns.
Aging / Elasticity
Wrinkle-Prone or Tight
Measures aging behavior, firmness, elasticity, and wrinkle risk.
Turning personalized skincare into a global system.
Dr. Baumann's science powers the Skin Type PRO platform, helping medical professionals deliver precise product, ingredient, and treatment recommendations based on the unique biology of each skin type. Skin Type PRO translates the Baumann Skin Types system into a scalable workflow for practices.
