Seaweed: Our Signature Ingredient for Your Best Skin

Marine algae, known more commonly as Seaweed, is more than just a nutrient-dense superfood. Seaweed is a superstar of the clean skincare world. Packed with minerals, antioxidants, amino acids and omega-3 fats, Seaweed is the not-so-secret ingredient of our plant-based OSEA formulas. But how exactly do we harness the power of the sea? Read on for everything you need to know about our signature ingredient.

The Basics

Marine algae is a member of the Protista kingdom, so while Seaweed has many plant-like attributes, i.e. using chlorophyll for photosynthesis, it is not technically a plant. Seaweed is found in salt water and is essential to the dynamic marine ecosystem, providing food and shelter for all kinds of sea creatures. Seaweed is typically classified as one of three groups: brown, red or green algae. You’ll find mostly brown and red algae in our products.
