What is Blue-Green Algae?
Blue-green algae thrive in mineral-rich subsystems such as volcanic ponds and alkaline lakes. Ancient civilizations cared about your nutritional properties, but today skincare formulators are taking advantage of its bioactive compounds:
- Phycocyanin: A strong antioxidant that helps reduce inflammation and redness.
- Chlorophyll: Detoxifies pores and helps fight environmental stressors, such as pollution.
- Amino Acids & Vitamins: Rich in B12, iron, and magnesium to strengthen the skin barrier.
It’s often likened to chlorella (another green algae) but is notable for having more protein, which is great for regrowing damaged or aging skin.

Types of Skincare Products with Blue-Green Algae
1. Serums
Lightweight formulations often mix algae extract with peptides or vitamins to address specific needs such as firming or brightening. Seek out “anti-pollution” or “barrier repair” products.
2. Moisturizers
Hydrating oils and creams laced with spirulina or cyanobacteria offer lasting moisture. Many vegan options combine algae with plant-based squalane for a non-greasy finish

Algae’s anti-inflammatory abilities help de-puff and lighten dark circles in fragile eye-area formulations.
