Trial centre
Complife Italia S.r.l, Italy.
Objective
To test whether Bio‑Oil Skincare Oil (Natural) is likely to cause acne and
comedones (pimples).
Sample
20 participants, 14 female and 6 male, of varying ethnicities with acne prone
skin. Age of participants: 18—65.
Methodology
Controlled study. 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 (Natural)) and a positive control
(lanolin alcohol, a known comedogenic product).
Skin reactions were clinically evaluated under the supervision of a dermatologist
15 minutes after the removal of each patch to compare the presence of
comedones before and after each product application.
Result
Bio‑Oil Skincare Oil (Natural) was found to be non-comedogenic. The area to
which Bio‑Oil Skincare Oil (Natural) was applied showed no significant difference
to the negative control area. The positive control induced acne.
