In the Patagonia Sea, at the southern end of South America, seaweed grows in abundance, which is where OSEA sources this amazing ingredient.

Red algae,  also known as Gigartina Skottsbergii, is the  protective algae, in that it deeply hydrates, promotes the appearance of youthful firmness, helps protect skin from external aggressors such as wind and air pollution, and it is also rich in polysaccharides, vitamins, and minerals.

This algae is great in repairing the acid mantle, our skin’s protective barrier.

This algae is pretty much the basis of all of our facials—we make a soothing gel form of this dried algae and mix it into many products, as well as use it alone as massage oil! It almost feels like aloe, and has similar effects, but it contains other fatty acids, vitamins, and minerals.


Undaria Pinnatifida, or more commonly known as  Brown Algae, is a very useful algae such that it is rich in iodine, iron, potassium, calcium, and vitamins B1, B2, B3, B6, and B12.

It also contains Fucoidan, a hydrating compound that promotes a youthful plump appearance. It also contains natural hyaluronic acid (hydration!), while slowing down the aging process by reducing the appearance of fine lines and minimizing redness.

We use the Undaria argan oil as our massage oil during our facials, making the most relaxing part of the treatment, just as beneficial for the skin as the other steps in the process.


Macrocystis Pyrifera is  Giant Bladder Kelp that aids in overall purifying the skin. It removes impurities, decongests skin, and is antibacterial, making it a great source for acne treatments. It also helps minimize irritation and uneven skin texture due to  its abundance of vitamins, minerals, fatty acids, and antioxidants.
