Q: Uneven skin tone study, 2011

Trial centre Thomas J. Stephens & Associates, Inc., Texas, United States of America Objective To evaluate the efficacy of Bio‑Oil Skincare Oil in improving the appearance of uneven skin tone and mottled pigmentation when used by women with mild to moderate photodamaged (ageing) skin on the face and neck. Sample Subjects: 67 female participants of varying ethnicities with clinically determined mild to moderate photodamage on the face and neck. Bio‑Oil Skincare Oil treatment cell included 35 subjects and the no treatment cell included 32 subjects. Age of participants: 30 to 70. Methodology Randomised, controlled, efficacy grader-blinded. Subjects participated in an initial screening evaluation followed by a 1-week washout period. Product applied to the face and neck twice daily for 12 weeks. Application performed under supervision at baseline visit. Clinical evaluations conducted at 0, 2, 4, 8 and 12 weeks. Subjects were clinically graded separately on the face and neck for uneven skin tone and mottled pigmentation. Result Bio‑Oil Skincare Oil is efficacious in improving the appearance of uneven skin tone and mottled pigmentation in photodamaged (ageing) skin. After 4 weeks a statistically significant result was achieved for both parameters on the face and neck. After 12 weeks 86% of subjects in the Bio‑Oil Skincare Oil treatment cell showed a statistically significant improvement in uneven skin tone on the face, 71% of subjects in mottled pigmentation on the face, 69% in uneven skin tone on the neck and 60% in mottled pigmentation on the neck.
