Science & Benefits

Macrocystis Pyrifera is a large brown kelp. While functionally an excellent humectant and skin-firming agent, its high natural concentration of iodides acts as a follicular irritant. Iodides can trigger inflammatory responses within the pore, leading to sudden pustular breakouts. It is a logical 'avoid' for users with cystic or inflammatory acne, as the minerals intended to nourish can inadvertently exacerbate the inflammatory cascade.
