Sensitive Skin Test, 2006
Trial centre
Future Cosmetics, Pretoria, South Africa.
Objective
To test whether Bio-Oil causes skin irritancy on subjects with sensitive skin.
Sample
Subjects: 21 participants. Age of participants: 18 to 65. Selection criteria: Subjects with known sensitive skin were selected and exposed to a positive control (lactic acid) to verify their sensitive skin status.
Methodology
Randomised and controlled. 3 areas were evaluated: area to which deionised water was applied (negative control), area to which Bio-Oil was applied, and area to which Sodium Lauryl Sulfate 1% solution was applied (positive control - a known skin irritant). Test products applied via a patch to the volar forearm and removed after 24 hours. Skin evaluated and reactions noted at 24, 48, 72 and 96 hours after application. Dermatologist present during the evaluations. Skin reactions rated on a scale from 0 - 4 (with 0 being no response and 4 being fiery redness).
Result
Bio-Oil was found to be a non-irritant product for subjects with sensitive skin. No subjects experienced any adverse reactions to Bio-Oil. Bio-Oil had an average reaction value of 0.03 over the period of 96 hours. Bio?Oil performed better than deionised water (negative control).
