COMEDOGENICITY & ACNEGENICITY
FUTURE COSMETICS, PRETORIA, SOUTH AFRICA, 2006
Objective: To test whether Bio-Oil is likely to cause acne and comedones (pimples).
Sample: 21 participants (17 female and 4 male of varying ethnicities) 50% prone to acne.
Method: Randomized and controlled. Product applied twice daily for 28 days. 3 areas evaluated: untreated area (negative control), area to which Bio-Oil was applied, an area to which acetylated lanolin alcohol was applied (positive control - a known acnegenic product). Test products applied to the upper back (scapular) region.
Result: Bio-Oil was found to be non-acnegenic and non-comedogenic. An area to which Bio-Oil was applied showed no significant difference to the untreated area. Positive control induced acne.
