The healing benefits of seaweed and algae from around the world
The sea has long been a source of healing. Thalassotherapy, from the Greek thalassa (“the sea”) and therap (“treat”), has been around for centuries: It uses seawater, mud, clay and protein-rich algae to restore the body’s natural chemical balance. Seawater and blood plasma have an almost identical chemical composition, which makes seawater the perfect solution to replenish the body’s minerals. Algae and seaweeds, which are a type of algae, contain strong antioxidants and a variety of beneficial vitamins to help protect your skin against free radicals, and can aid in treating a number of skin conditions, including psoriasis and eczema.
Now, companies are harnessing the power of the sea through concentrated algae-based products. Technology has advanced tremendously, helping to preserve vital nutrients and create potent extracts. But in addition to harvesting and processing methods, it’s very important to know where materials are sourced to ensure they are free from impurities.
On a trip to Buenos Aires, I followed in the footsteps of Jenefer Palmer, founder of the algae-based skincare line OSEA. I headed to Home, a boutique hotel in the trendy Palermo district, where Palmer was inspired to start her company after having indulged in a fresh Patagonian algae bath there. She traced the algae all the way south to “el fin del mundo”—the end of the earth—and a skincare line was born. Home now offers OSEA facials, which are so relaxing that you might find yourself lulled into a deeply meditative state.
To round out my South American algae experience, I visited the newly renovated CIELO Spa in the Four Seasons Hotel Buenos Aires. Its Remodeling Seaweed Treatment uses caffeine, seaweed and seawater to help slim the body and improve skin tone. Following a thorough exfoliation, my therapist applied marine powder, marine serum and a marine-based body cream. Emerging from the cocoon an hour and a half later, my parched post-plane skin felt completely rejuvenated.
These marine products—which use natural algae and sea salts sourced from Patagonia, France, Canada, Israel and Ireland—will keep your skin looking fresh and hydrated all year round.
