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. Our barrier repair moisturizer is a 50 SPF facial sunscreen that doubles as a moisturizer and is packed with skincare goodies to help minimize redness, breakouts, and inflammation. The hero ingredient is our proprietary Macrolipid Complex which combines the power of pacific seaweed extracts, hydrating ceramides, and linoleic acid from seabuckthorn oil. It leaves the skin with a light dewy finish that doesn't feel oily, protects your skin from sun damage, and promotes skin barrier regeneration.Read their story
