Researchers created a grape seed oil microemulsion that delivered resveratrol (an anti-inflammatory compound) four times deeper into skin compared to a basic solution. The formulation stayed stable for 60 days at room temperature and passed safety tests, making it a potential option for treating inflammatory skin conditions—though human trials haven't happened yet.

Scientists developed two microemulsion formulas with different water and oil ratios, then tested how well resveratrol penetrated pig skin samples and checked for safety using lab-based irritation tests.
