How To Find Out My Skin Type?

There is only one way to diagnose your skin type accurately and scientifically. Take the quiz here on our website or find a STS approved doctor in your area. The scientific name of the 16 Skin Types Quiz is the Baumann Skin Type Indicator. We call it the Skin Type Solutions Skin Type Quiz. Only STS has the right to use this skin type test. The Skin Type Solutions Skin Type Quiz has been tested on hundreds of thousands of people worldwide and is the only valid skin type quiz.   

How Was the Skin Type Solutions Quiz Validated?

The original testing began July- November 2005 at the University of Miami Department of Dermatology under IRB supervision.  400 participants were patients at the Dermatology Clinic at the Edelman Building of the University of Miami medical campus. Two trained interviewers were assigned to intercept all clinic patients as they entered the waiting room of the clinic. Participation in the survey was entirely voluntary.  Informed consent was obtained before the survey was given to the respondents. Once enrolled, demographic information and a dermatological history were obtained by the two interviewers. Next, the study participants were given the survey and asked to complete the Baumann Skin Type Indicator (BSTI) questionnaire, version 1. This table shows the demographics of the initial 400 participants.

The Baumann Skin Type (BST) result of each of these patients was compared to the CPT diagnosis code (this is the official skin disease diagnosis code used by insurances to reimburse for the office visit) of the dermatologist who saw them in the University of Miami clinic.  This dermatologist was unaware of the participants BSTI quiz result to eliminate bias. This preliminary study showed that the BSTI questionnaire could accurately diagnose the underlying skin problems of the participate prior to seeing a dermatologist.

How To Find My Skin Type When I Don’t Have A Dermatologist 

From 2006- 2020 the questionnaire known as the Baumann Skin type Indicator was tested on patients around the world and shortened to contain only the most pertinent questions. In 2006, data was compared from participants online versus patients in dermatology practices around the world to see if there was a difference in incidence of skin types from those who chose to see a dermatologist versus those who did not have a dermatologist.  52,862 participants took the skin type quiz. The data showed that there was no significant difference in skin types between those who took the quiz online versus saw a dermatologist in their office.  We highly recommend that you find a STS trained doctor in your area or schedule an online consult- but if you cannot- you can be assured that the skin type quiz can accurately identify your skin type.

Does the Skin Type Quiz Work For All Ethnicities?

Yes!  This has been proven multiple times. This study also showed that there was not a significant different in skin types in the US vs China and Korea.  The study showed that worldwide  oily skin types (which included normal skin types in the Baumann Skin Typing System) were more common than dry skin types.

What Ages Does the Skin Type Test Work For?

The skin type test has been validated on men and women and boys and girls from ages 13 and up.  It has not been tested on ages under 13.

What Skin Type Test Do Dermatologists Use?

The same skin type quiz used here on our web site is used by dermatologists around the world using our patented software. From 2014- 2020 many studies have used the Baumann Skin Typing System to categorize patients scientifically into skin types.  In 2016, a Korean study showed that the BSTI questionnaire was as accurate as a dermatologists evaluation in determining skin type. In 2017 the skin typing system was shown to be valid to evaluate post adolescent acne and valid in Korean females and in 2019 was shown to be valid when used in males. In 2020 this study showed that the Baumann Skin Typing System can be used to prescribe skin care. The skin typing system is described in many dermatology and physician textbooks.

Does the Skin Type Quiz Have Different Versions?

To shorten the number of questions needed to determine the Baumann Skin Type, a study was done that compared sebum secretion measurements with a sebumeter in 100 participants. The questions that correlated best with the amount of sebum produced were kept in the questionnaire while the ones that did not correlate as well were eliminated. The quiz became shorter at this time.  In 2005, The Skin Type Solution- Leslie Baumann MDs a New York Times Bestselling Book- contained an early paper version of the questionnaire.  It was converted to digital and shortened again in 2014.  The most recent version of the Baumann Skin type quiz is available only here at and in STS approved doctors that can be found here.
