Why I Build Our Face Moisturizer Around Spirulina
March 31, 2026
The first time someone sees green moisturizer, they usually make a face. I understand. But the green is the whole point, and it comes from spirulina.
Phycocyanin, the blue green pigment
Spirulina is loaded with a pigment protein called phycocyanin. It is one of the most studied parts of the plant, and the research focuses on its antioxidant and anti-inflammatory behavior. Several lab studies have looked at how phycocyanin helps skin cells stand up to UVB stress, which is one of the bigger day to day drivers of dull, tired looking skin.
There is also a growing body of work on spirulina in cosmetics specifically, looking at hydration, the appearance of fine lines, and antioxidant support. The skin is constantly dealing with free radicals, and antioxidants are part of how we help it stay comfortable and resilient. That is a structure and function idea, not a medical one.
The rest of the blend
In our Face Moisturizer, spirulina works with rose, horsetail, oatstraw, and yerba santa. Horsetail brings minerals like silica. Oatstraw adds calming antioxidants. Rose is gentle and soothing. I blend the infused oils with beeswax and castor oil so it sits as a steady, protective cream rather than a greasy layer.
It is simple, it is green, and it earns its place on your face and hands.
