Stretch mark oil is a topical product that is applied to the skin to help reduce the appearance of stretch marks. It typically contains a combination of ingredients such as vitamins, minerals, and oils that are believed to nourish and hydrate the skin, promote collagen production, and improve skin elasticity. Some common ingredients found in stretch mark oils include cocoa butter, shea butter, coconut oil, vitamin E, and centella Asiatic extract. It is usually applied twice a day, morning and night, by massaging it into the affected area until it is fully absorbed. It is not a miracle product and results may vary
