OSEA Malibu is deeply committed to sustainability, from ingredient sourcing to packaging. They use sustainably harvested organic seaweed as the base of their products and package them in recyclable glass bottles to minimize plastic use. The brand is Climate Neutral Certified, which ensures they measure and offset their carbon emissions through projects like coastal restoration​.

OSEA is also Ocean Positive, meaning they offset more carbon than they create by investing in projects that sequester carbon from marine environments. Their recycling program in Los Angeles allows customers to return glass containers for proper disposal, which contributes further to reducing their environmental footprint​.

OSEA uses clean, non-toxic ingredients that are vegan, cruelty-free, and free from harmful chemicals such as parabens, phthalates, and sulfates. The brand has been a pioneer in clean beauty since the 1990s, with a long-standing commitment to safe, effective, and eco-conscious skincare. Their formulations include nutrient-dense seaweeds, plant-based oils, and hyaluronic acid, ensuring their products can deliver results without compromising health or the environment

OSEA is a woman-founded, family-owned business, and they prioritize social responsibility in their operations. They offer living wages in their production processes and support environmental and social causes, including Ocean Cleanup projects and partnerships with 1% for the Planet. Additionally, their products are Leaping Bunny certified, ensuring that no animal testing is involved.

Though OSEA is active in supporting environmental causes, further transparency in labor practices and supply chain details would improve their social responsibility score.
