Since 1987 Bio‑Oil® has been researching how oil can be used to create more effective 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 skin appearance. And two dry skin products, a gel with 83% oil for very dry skin, and a lotion with 42% oil for daily moisturising. (Note: Skin dryness varies from person to person; it is recommended to choose according to your own skin condition.)
