Researchers created a grape seed oil microemulsion that delivered resveratrol (an antioxidant compound) 4x 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 candidate for treating inflammatory skin conditions.

Scientists mixed grape seed oil with water and surfactants in specific ratios, then tested how well the resulting microemulsion penetrated pig skin and whether it was safe for topical use.
