Necessity really is the mother of invention. Take Diana Lussenden Stewart, for instance. When she couldn’t find products free from fragrance and synthetic ingredients for her baby’s itchy skin, she decided to make her own. With her knowledge of aromatherapy and healing remedies, she began blending organic oils, such as sunflower seed, Roman chamomile, olive, rose hip, and lavender, to make a soothing cream. As her daughter’s skin cleared, Diana’s friends began asking for their own jars of the baby cream. She mixed up more products in her home kitchen, including a stretch mark belly oil.
