Acne scar study, 2012

Q: Acne scar study, 2012

Trial centre Dept. of Dermatology, Peking University First Hospital, Beijing, China. Objective An exploratory study to assess the efficacy of Bio‑Oil Skincare Oil in improving the appearance of facial acne scars on Chinese subjects. Sample Subjects: 44 Chinese subjects with newly formed acne scars on the face (<1 year old). Bio‑Oil Skincare Oil treatment cell included 32 subjects and the no treatment cell included 12 subjects. Age of participants: 14 to 30. Methodology Randomised, controlled, efficacy grader-blinded. Subjects participated in an initial screening evaluation followed by a 1-week washout period. Product applied twice daily for 10 weeks. Application performed under supervision at regular intervals. Assessments conducted at 0, 4, 8 and 10 weeks included the following: Global scarring score (GSS) assessment by the investigator, measurement of acne scar colour / redness using a chromameter, measurement of sebum levels using a sebumeter, documentation of number of comedones and inflammatory lesions by a dermatologist. Subjects also completed selfassessment questionnaires at each visit. Result The best result of the clinical grading was in Bio‑Oil Skincare Oil’s ability to reduce the erythema or redness of macular (flat) acne scars, with the overall skin becoming brighter. Results of the self-assessment questionnaire showed that more than 84% of subjects experienced an improvement in the overall condition of their acne scars and more than 90% experienced an improvement in scar colour. Acne count and sebum measurement results showed that using Bio‑Oil Skincare Oil does not cause or aggravate acne or increase sebum secretion.
