Inspired by her grandmother’s lifelong love of the sea, Jenefer Palmer set out to share her passion through a plant-based skincare line infused with elements of the ocean. Distraught by the harmful chemicals she found in other products, Palmer resolved to craft her formulas with non-toxic, nourishing ingredients. While OSEA has now expanded into a world-renowned skincare line, their commitment has stayed the same—producing effective, wholesome products as pure as the ocean itself.
