Marine Algae Skincare | Folklore, Benefits & Innovation
Marine Algae in Skincare: Ocean Born Renewal, Sustainably Grown From Ocean Depths to Skincare Rituals
Marine algae, sometimes called seaweed or sea plants, have been revered in coastal cultures for centuries. From Scottish kelp baths to Japanese nori wraps, these nutrient rich organisms were used to nourish skin, strengthen hair, and even heal wounds. Today, modern science confirms what tradition extolled: marine algae are among the most effective natural ingredients for restoring balance and radiance to the skin.
Marine algae skincare is more than a beauty trend; it is a sustainable, science-backed way to restore vitality to the skin. By combining ancient wisdom with innovative cultivation, this ocean-born ingredient delivers deep hydration, firming power, and lasting protection — a true ritual for radiant, resilient skin.
A Circular Ingredient with a Low Footprint
At Raven Botanicals, the marine algae we use do not come from delicate wild stocks. Instead, they are cultivated in an eco facility in France that places sustainability at the heart of its practice. By growing algae in closed, land based tanks, their purity, potency, and traceability can be guaranteed while leaving fragile marine ecosystems untouched.
What makes this ingredient especially exciting is the circularity of its production. During growth, algae release gases as part of their natural cycle. Rather than letting this go to waste, the facility captures the gases and repurposes them to heat the building itself. Nothing is wasted and every stage of cultivation is designed with minimal environmental impact in mind. It is skincare powered by innovation, rooted in nature.

Folklore and Ocean Myths
The sea has always held a place in human imagination, a source of mystery, healing, and transformation. In Scotland, kelp was once burned to create “kelp ash,” an important trade product in the 18th century, but before that, it was gathered for food and medicine. Fisherfolk would pack seaweed into wounds to speed healing, and in island communities, kelp baths were recommended for rheumatism and weary muscles.
Further afield, in Japanese folklore, seaweed was considered a gift from the sea gods, bringing health and vitality. In Norse mythology, the goddess Rán was said to ensnare sailors in her seaweed net, binding human fate to the ocean’s depths. Even today, seaweed carries that sense of enchantment, an otherworldly plant born of tides and moonlight, bridging earth and water.
To weave these stories into skincare is to honour algae’s ancient place in human ritual, now supported by science but still carrying the whisper of folklore in every strand.
How to Use Marine Algae in Skincare
Marine algae extracts are beautifully versatile.
Daily hydration: Look for serums and moisturisers infused with algae to help skin stay plump and resilient.
Barrier support: Algae help strengthen the skin’s natural defences, ideal for those experiencing dryness, sensitivity, or exposure to urban pollution.
Brightening and renewal: Over time, algae extracts promote even tone and smoother texture.
Recovery rituals: Masks or oils containing algae calm redness and replenish skin after stress, sun exposure, or travel.
At Raven Botanicals, we blend sustainably grown marine algae with other botanicals to create skin rituals that hydrate, defend, and restore, with sustainability threaded through every drop.
