subjects. Age of participants: 30 to 70.
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.

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.
