Improving Sensitive Skin Diagnosis by Integrating Diagnostic Questionnaires, Lactic Acid Sting Test, and Lipid Profiling.

ABSTRACT:

Background

Sensitive skin (SS) is characterized by subjective symptoms, including burning, stinging, and itching, which occur with the use of cosmetics. Over 40% of the population experiences skin sensitivity, yet no clear standards for evaluating SS have been established.

Aim

To diagnose SS by combining lactic acid sting test (LAST), skin irritation tests, and biophysical measurements with a developed questionnaire, validating the characteristics through quantitative analysis of natural moisturizing factors (NMF) and lipid profiles.

Methods

The diagnostic questionnaires were administered to 975 healthy women from Beijing and Shanghai to evaluate their skin sensitivity. Among these, 154 participants from Beijing and 153 from Shanghai underwent physiological testing, w
