Experimental Data
1. Anti-Oxidative power
Dongbaek Oil is high Oxygen Radical Absorbance Capacity (ORAC) that is a method of measuring antioxidant capacities in biological samples in vitro. Subsequently, the degree of antioxidant-mediated protection is quantified using the antioxidant trolox (a vitamin E analogue) as a standard. Results for test samples (foods) have been published as "trolox equivalents" or TE.
2. Skin Barrier Recovery
 |
• Vehicle: O/W cream
• Glycerin: O/W cream contains 2% Glycerin.
• Dongbaek Oil: O/W cream with 2% Dongbaek Oil |
