It is not recommended to use toothpaste or cooking oil on the face. Toothpaste contains ingredients such as menthol, fluoride, and abrasives that can be too harsh for the delicate skin on the face, causing dryness, irritation, and potentially even more severe reactions. As for cooking oil, while it may help moisturize the skin temporarily, it can also clog pores and lead to acne breakouts. It is always best to use skincare products specifically formulated for the face, as they are designed to address specific skin concerns safely and effectively.
