Osea makes a variety of skincare products featuring seaweed as an active ingredient.

Clean beauty since 1996. For over 27 years, we’ve been on a mission to create clean, seaweed-infused skincare that respects the natural world and makes skin look and feel its absolute best. In 1996, we set a new industry standard by prioritizing naturally-derived ingredients, chosen for their safety, efficacy and backed by the latest scientific research. Today it’s called clean beauty, but in our family, it is what it has always been: a simple idea that the ocean should be part of everyone’s life—and the conviction that it already is.

The ocean is our deepest inspiration. We use seaweed because it’s a superfood rich in vitamins, minerals and nutrients. The benefits of seaweed are endless. Different species of seaweed can provide a myriad of results, including anti-aging and moisturization. Our seaweeds are sourced from around the world, based on scientific data.

Skin Care

Osea earns strong reviews for delivering spa-like textures and real hydration—many cite Undaria Algae Body Oil, Ocean Cleanser, and Atmosphere Protection Cream as effective staples—yet the brand divides on fragrance intensity and can irritate sensitive skin. Reviews also flag packaging inefficiencies (hard-to-empty pumps, leaks) and occasional pilling or residue, making Osea a luxurious but sometimes fussy choice for scent-sensitive or reactive users.
