To assess the potential of Bio‑Oil Skincare Oil to cause skin irritation.
25 participants, 19 male and 6 female, all with sensitive skin according to lactic acid stinging test. Age of participants: 18 to 65.
Randomised and controlled. Two areas were evaluated: area to which a negative control was applied (demineralised water) and an area to which Bio‑Oil Skincare Oil was applied. Tests were applied to the back of the hands of participants for a period of 48 hours using a Fin chamber. Skin reactions were evaluated under the supervision of a dermatologist, to assess primary skin irritation at 15 minutes, 1 hour and 24 hours after patch removal. Skin reactions were rated on a scale from 0 – 4 (with 0 being no erythema, oedema, or other types of skin irritation, and 4 being serious cause of erythema and oedema, indicating swelling and dark red appearance beyond the application area.
No subjects experienced any adverse reactions to the test product, with a visual score of 0 (zero) recorded for all subjects at all timepoints. The skin tolerability of Bio‑Oil Skincare Oil was deemed ‘non-irritating’.
