THE SCIENCE OF SEAWEED

Kelp-Powered Care for Daily Skin Support

High Dive brings SPF 50 protection together with kelp extract, ceramides, and niacinamide for a sunscreen that feels like skincare.

Kelp extract offers ocean-derived minerals, polysaccharides, and antioxidant-rich compounds that make it a thoughtful ingredient for daily skin care. In High Dive, it helps skin feel conditioned, hydrated, and supported while complementing ingredients chosen for everyday barrier care.

Ceramides help support the skin barrier, niacinamide helps skin look balanced and comfortable, and SPF 50 helps protect against daily UV exposure. The lightweight, non-greasy finish makes the formula easy to wear on bare skin or under makeup, so sun protection feels like a natural part of your morning routine.

We use kelp because it connects skin-first benefits with a smarter source story. It grows quickly in the ocean without freshwater or fertilizer, giving Neptune Ave. a marine ingredient rooted in both performance and responsibility.

Seaweed is Changing the World
It keeps growing and growing: Seaweed is one of the fastest-growing organisms on the planet. Some species can grow up to half a meter a day! This rapid growth rate means that kelp forests can be harvested regularly without damaging the overall population.
No Need for Freshwater or Fertilizer
Unlike land plants, kelp doesn't require freshwater or fertilizer to grow! It thrives in saltwater, absorbing nutrients directly from the ocean. This makes it a sustainable option compared to ingredients that rely on freshwater resources or gnarly synthetic fertilizers.
Habitat Creation
Kelp forests create a habitat for a variety of marine life, contributing to biodiversity. Harvesting kelp sustainably ensures the preservation of these important ecosystems.
Potential for Biofuel
Researchers are exploring the use of kelp as a sustainable source of biofuel. While this doesn't directly relate to skincare, it's another factor that contributes to the overall sustainability of kelp as a resource.

Pharmaceutical Properties

While more research is needed in human clinical trials to validate these findings, a study published in the Journal of Cancer Research and Clinical Oncology in 2016 highlighted that laminarin induced apoptosis, or cell death, in human colon cancer cells.

The polysaccharide exhibited significant anti-proliferative activity, essentially preventing the cancer cells from multiplying. Research has also shown that laminarin can exhibit anti-tumor properties. A 2015 study published in the International Journal of Biological Macromolecules demonstrated that laminarin could inhibit the growth of certain types of tumors, and it was proposed as a promising candidate for tumor therapy. The study suggested that laminarin achieved this by boosting the immune response and inhibiting angiogenesis (the formation of new blood vessels that tumors need to grow).
