Try Bio-Oil Dry Skin Gel to combat irritating dry skin and experience full body skin hydration. Our unique formula targets the top layer of skin to protect the moisture layer and soothe the skin. Dry skin is a common condition caused by insufficient oil production in the skin, which causes the top layer of the skin to dry out.Traditional products such as creams, lotions and body butters are made primarily from water. Most of this water evaporates when coming into contact with your skin. Bio-Oil’s specialist dry skin formula is easily absorbed by the skin and is composed of only 3 percent water. This helps the skin to retain moisture.
