Bestsellers

From body butter and salt scrubs to cleansers and eye serums, we have something for each skin type.

Our best OSEA products for the body include Undaria Algae™ Body Oil, an Editor’s Pick, featuring white lupin to enhance the appearance of firmness and a botanical oil blend to deeply moisturize dry skin. The award-winning Salts of the Earth Body Scrub features mineral-rich salts from around the world, gently exfoliating to reveal smoother-looking skin. Meanwhile, shea butter and wild Gigartina seaweed have a glow-enhancing effect.

To put your best face forward, try our Hyaluronic Sea Serum — an essential hydrator suitable for all skin types. The formula contains Japanese Miru seaweed to replenish and balance the skin’s natural moisture level, as well as the plant-based amino acid betaine, which helps maintain optimal water balance.

Our Dream Night Serum with Bio-Retinol works while you rest. Bio-retinol, a potent extract derived from green microalgae, is an alternative to traditional retinol, which can be irritating. In a clinical study, 100% of participants showed visible improvement in crow’s feet and fine lines after one use*.
*Based on an independent third-party clinical study conducted on 32 women.

Our ingredients are scientifically formulated, safe, effective, vegan and cruelty-free. We combine our seaweeds with the most renowned skincare actives that have proven efficacy through in-vivo and in-vitro testing.

Seaweed is a superfood rich in vitamins, minerals and nutrients. Different species of seaweed offer various benefits, including anti-aging and moisturizing properties. We source our seaweed from around the world. Undaria seaweed is a standout in numerous products. It’s a rich source of amino acids, antioxidants and nutrients that replenish the skin’s natural moisture barrier.

Other key ingredients in our formulations include snow mushroom, aloe vera, vitamin C and vegan lactic acid.

Many OSEA best sellers are suitable for sensitive skin, including a fragrance-free version of our bestselling Undaria Algae™ Body Oil, which is hypoallergenic, dermatologist-tested and recognized by the National Eczema Association with the Seal of Acceptance™.

Our Advanced Protection Cream also has the Seal of Acceptance™ from the National Eczema Association. Powered by marine moisture, this product is suitable for sensitive and dry skin. The marine extract soothes and softens the skin for a healthy appearance, while the biomimetic lipid complex supports the skin’s moisture barrier for a hydration boost.

Yes, they are! Our best vegan skin care products are certified by PETA and cruelty-free certified by Leaping Bunny. We also use sustainable packaging materials and prioritize naturally derived ingredients.

In 2002, we became the first company to sign The Compact for Global Production of Safe Health and Beauty Products, an initiative launched by the Environmental Working Group. Their mission is to ensure products are “free of chemicals that are known or strongly suspected of causing cancer, mutation or birth defects.” We continue to lobby our legislatures and advocate for safe skincare for all.
