What does the kelp extract contribute to the formula?

Macrocystis Pyrifera, commonly known as giant brown kelp or giant bladder kelp from Antarctic waters, is among the most nutrient-rich forms of seaweed used in skincare. It is valued for its high iodine content alongside a broad spectrum of vitamins and minerals that benefit the skin when applied topically. In the Seaweed Soap, kelp contributes calming and soothing properties that help counterbalance the stimulating effect of physical exfoliation, leaving skin feeling settled and comfortable rather than reactive after use. Algae is also included separately in the formula, adding natural skin conditioning properties that help improve the overall appearance and feel of cleansed skin. Together, these two marine-derived ingredients give the soap its signature character and are the reason it has maintained a loyal following for decades.
