What algae is best for skin?

Blue algae has many names—blue-green algae, cyanobacteria, spirulina—but what skincare experts are laser-focused on is that the pigment-rich ingredient can work wonders when applied to the skin. For decades now, scientists have known that the pigment in blue algae is a great source of antioxidants.

Is algae bad for skin?

In cosmetics, algae act as thickening agents, water-binding agents, and antioxidants. Some algae are also potential skin sensitizers. Most of these are beneficial for skin, as emollients, soothing agents, or antioxidants. New research shows forms of brown algae show promise for improving the appearance of aging skin.

Is green algae good for skin?

Skin Care Benefits of Blue-Green Algae and Red Algae Like land-based superfoods, blue-green and red algae are vibrant in color and contain antioxidant pigments that naturally protect the skin. These compounds boost the skin’s defenses against a variety of environmental stressors.
