What it is
Dioscorea Opposita Root Extract is obtained from the root of the Chinese yam, a plant long used as a food and in traditional preparations in East Asia. In cosmetics it is included as a plant-derived conditioning agent, valued for its mucilage and starch content that can lend a soft, moisturized feel. In a sunscreen it usually serves as a supporting botanical rather than a performance ingredient.

Botanical root extracts of this type are generally well tolerated in leave-on products. As with any plant extract, individual sensitivity is possible, though reports are uncommon.
