Science & Benefits
A generic term for extracts derived from various seaweed species. Many species, particularly brown and red algae, are high in iodides and carrageenans that trigger 'acne cosmetica' by irritating the follicle lining and causing rapid comedone formation. While it offers mineral-rich hydration, the comedogenic risk is far too high for acne-prone skin. It should be considered a 'red flag' ingredient in leave-on products.
