Background Skin diseases are known to negatively affect self‐image and to have detrimental psychosocial effects. Oily skin is a cosmetic skin problem that women often describe as ‘invalidating’. Objective To develop and validate a questionnaire to assess the psychological and psychosocial effects of oily skin condition in women and the outcome of a targeted cosmetic skincare treatment. Methods We developed and validated a concise 18‐item questionnaire [oily skin self‐image questionnaire (OSSIQ)] to assess perception, behavioural, and emotional consequences associated with oily skin condition. The questionnaire was then used to assess the effects of a skincare treatment for oily skin and compare them with sebum level measurements. Results The 18‐item questionnaire clearly distinguished the oily skin group from the control group. Responsiveness, reliability, and construct validity showed satisfactory performance. The questionnaire provided a relevant assessment of the psychological benefits associated with the skincare programme. Conclusion The OSSIQ is a valid tool that can be used to monitor the benefits of cosmetic skincare treatments
