Undaria Algae™ Body Oil

Clinically proven to instantly improve the look of skin elasticity and deliver deep moisturization. Our seaweed-infused body oil is a rush of antioxidant-rich hydration that softens, nourishes and firms like no other. Visibly improves sagging skin for a toned and sculpted look. Rich yet never greasy, this intoxicating aromatherapy elixir enhances every inch. Mineralize, moisturize and glow! To create this one-of-a-kind oil, we soak hand-harvested Undaria Algae in barrels of oils to infuse the vitamins and minerals. Due to the artisanal manner of production, variation in color is normal. This oil contains Undaria Seaweed and as such, a naturally occurring seaweed sediment may be present at the bottom of your bottle. This is completely normal and does not affect the quality or efficacy of the product.
