I saw results 1 week after 1 use! I used this on stretch marks and then applied a hyaluronic acid afterwards. I am shocked! I thought I’d never be able to see an improvement this fast. Of course the stretch marks are still there but after only 1 use, there is a huge improvement – not as deep, blends more with my skin, less noticeable! I am very happy with this product! I will continue to use this product once a week with hyaluronic acid afterwards. I do this at night time before bed. I would recommend this product to everyone.
