Grape seed oil is a cooking oil extracted from the seeds of grapes, often a byproduct of the wine industry. It has a light flavor and high smoke point, making it suitable for frying, sautéing, and salad dressings. Rich in vitamin E and polyunsaturated fats, grape seed oil is known for its potential health benefits, including antioxidant properties. It is also used in cosmetics and skincare products due to its moisturizing qualities and ability to improve skin texture.
