To test whether Bio‑Oil Skincare Oil is likely to cause acne and comedones (pimples).
Subjects: 20 participants, 14 female and 6 male of varying ethnicities with acne prone skin. Age of participants: 18 to 65.
Randomised and controlled. The product was applied on a disk of filter paper to the upper back region of participants. Patches were left in place for 48 to 72 hours, removed and applied again. A total of 12 patches were applied for 4 consecutive weeks. Three areas were evaluated by comparing a negative control (demineralised water), the test product (Bio‑Oil Skincare Oil) and a positive control (lanolin alcohol, a known comedogenic product). Skin reactions were clinically evaluated under the supervision of a dermatologist 15 minutes of the removal of each
patch and the presence of comedones was compared to before and after product exposure.
Bio‑Oil Skincare Oil was found to be non-comedogenic. The area to which Bio‑Oil Skincare Oil was applied showed no significant difference to the negative control area. The positive control induced acne.
