Since 1987 Bio‑Oil® has been researching how oil can be used to make better performing skincare products. To date four products have been launched. Two skincare oils, the original and a 100% natural version, both clinically proven to help improve the appearance of scars and stretch marks, and two dry skin products, a gel with 83% oil for very dry skin, and a lotion with 42% oil for daily moisturizing.
