Bio-Oil is a light moisturizing oil that is marketed to soften skin and improve its texture and elasticity. Its stand-out ingredient is the trademarked PurCellin Oil, which cuts through other, greasier ingredients in Bio-Oil to give the product a more sheer texture that can sink into dry, scarred or damaged skin.
What's in Bio-Oil
Aside from PurCellin Oil, Bio-Oil's ingredients include vitamin A and vitamin E, rose fragrance and botanicals in a base of mineral oil. Bio-Oil's primary botanicals are lavender, calendula, rosemary and chamomile oil. It also contains orange coloring and synthetic chemical additives.
Bio-Oil is used as a general moisturizing agent, either on its own or added to lotions or foundation. It's also used to minimize the appearance of scars and dark spots over time and soothe irritated skin. Bio-Oil has been marketed to help prevent and possibly treat stretch marks by softening and improving skin elasticity.
