Background The relationship between the subjective skin type and the casual sebum level was not fully clarified. Objectives To investigate the characteristics of subjective skin type and to find the relationship between the subjective skin types and the skin type‐related symptoms, casual sebum level, along with the objective skin type. Methods Seven hundred and nine patients, clinically diagnosed with acne, were included. The questionnaire and the casual sebum level measurement were performed. The determining symptoms of each subjective skin type were investigated. The 95% confidence interval of casual sebum level of each subjective skin type was calculated. Results The most frequent subjective skin type was the combination type. The dryness, tightness, and oiliness can be conclusive symptoms in determining the subjective skin type. The mean and the 95% confidence interval of the casual sebum level was highest in the oily skin type, followed by the combination, normal, and dry skin type. Conclusion We found that the subjective skin type was determined by the skin type‐related symptoms. The 95% confidence intervals of the casual sebum level of each subjective skin type were established. Based on the skin type‐related symptoms, the casual sebum level of acne patients can be estimated.
