About Neptune Ave.

Neptune Ave. brings marine biotechnology to modern skincare. Named after the ocean-front street in Encinitas where the coast shapes daily life, we set out to capture the town’s laid-back but purposeful spirit. Our formulas are powered by kelp bio-actives—compounds shown to strengthen the skin barrier, reduce water loss, and support deep, lasting hydration. Sourced sustainably off the California coast and backed by leading macroalgae research, every product blends science with intention. It’s skincare that feels elevated, grounded in nature, and built to perform.Read their story
