Formula Science
A proprietary marine concentrate engineered to replenish moisture, reinforce the skin barrier, and support skin resilience in the sun.
At the heart of every Neptune Ave. sunscreen is the Macrolipid Complex™—our signature blend of Pacific seaweeds, skin-identical ceramides, and nutrient-rich sea buckthorn oil.
Drawing inspiration from California's giant kelp forests, the complex combines moisture-binding marine polysaccharides with barrier-supporting lipids to leave skin feeling hydrated, comfortable, and resilient.
The Marine Layers
Derived from Giant Kelp, Red Algae, and Sugar Kelp, naturally occurring compounds such as fucoidan and laminarin help bind moisture to the skin while providing antioxidant support.
Benefits
Ceramide NG helps replenish essential lipids naturally found within the skin barrier, supporting smoother, healthier-feeling skin and helping minimize moisture loss.
Benefits
Naturally rich in fatty acids, including oleic acid, sea buckthorn oil complements the marine extracts and ceramides by helping replenish the skin's lipid environment and supporting a silky, elegant finish.
