Justine Kahn is a champion of the slow beauty movement and the founder of Botnia, a plant-based skincare line. I met with her at her home and mini-farm in the heart of Sausalito, California where we took a tour of her garden, made a simple calendula healing oil, and chatted about her unexpected journey into plant-based skin care. You won't want to miss a minute of her story or the how-to for making your own garden-to-table calendula oil.
