"Oil-free" refers to products or processes that do not contain oils, particularly in the context of cosmetics, skincare, and cooking. In skincare, oil-free products are designed to hydrate the skin without adding extra oil, making them suitable for oily or acne-prone skin types. These products often use water-based or gel formulations to provide moisture without clogging pores. In cooking, oil-free methods involve preparing food without the use of oils or fats. This can include techniques like steaming, baking, or grilling, which allow for healthier meal options. Oil-free diets are often promoted for weight management and heart health, focusing on whole foods like fruits, vegetables, and grains.
