Spirulina is the dried biomass of the blue-green cyanobacterium Arthrospira platensis, a nutrient-dense microalga that is 60–70% protein and rich in the blue pigment-protein C-phycocyanin, chlorophyll, beta-carotene, gamma-linolenic acid, B vitamins, and minerals. C-phycocyanin is a well-characterized antioxidant and anti-inflammatory that scavenges radicals and inhibits inflammatory enzymes [1], and reviews document spirulina’s antioxidant, immunomodulatory, and anti-inflammatory activity [2]. A spirulina-extract skin cream showed wound-healing and antioxidant activity in laboratory testing [3], and a cosmetic-science review positions spirulina as a promising multifunctional skincare active and natural colorant [4]. Its vivid green (whole powder) and blue (phycocyanin) make it useful as a natural pigment in soap and cosmetics. Sourcing from controlled cultivation is essential to avoid heavy-metal and microcystin contamination.
What is Spirulina made of?
Spirulina is cultivated in controlled alkaline ponds or photobioreactors, harvested, and spray- or freeze-dried; phycocyanin is water-extracted and purified. Constituents [2, 4]:
- C-phycocyanin (blue pigment-protein): Antioxidant, anti-inflammatory; natural blue colorant [1].
- Proteins and amino acids (60–70%): All essential amino acids; film-forming and hair-strengthening.
- Chlorophyll and carotenoids (beta-carotene, zeaxanthin): Antioxidant; green color.
- Gamma-linolenic acid (GLA) and other lipids: Anti-inflammatory, barrier-supporting.
- Vitamins (B1, B2, B3, B12 analog, E, K) and minerals (iron, magnesium, zinc, selenium): Nourishing.
- Polysaccharides (calcium spirulan): Antiviral and hydrating.
What skin type is best suited for Spirulina?
Spirulina suits all seven ORY® skin types as a nourishing antioxidant, with the strongest fit for dull and oily skin:
- Oily: Detoxifying masks; protein film and chlorophyll absorb oil.
- Acne-prone: Anti-inflammatory phycocyanin; antimicrobial activity.
- Combination: Nutrient masks and serums.
- Mature: Antioxidant protection; amino acids support collagen; GLA supports barrier.
- Normal: Nutrient boost and antioxidant defense.
- Dry: Extract in creams with GLA-rich oils.
- Sensitive: Anti-inflammatory phycocyanin extract at low levels; patch test (protein allergen potential).
What hair type is best suited for Spirulina?
Spirulina’s protein and nutrients strengthen hair and nourish the scalp:
- Dry or damaged: Amino acids and protein reinforce the fiber; masks add softness.
- Mature or thinning: Nutrient-rich scalp support (iron, zinc, B vitamins, antioxidants); cosmetic claims only.
- Color-treated or chemically processed: Protein repair and antioxidant protection.
- Curly and coily: Protein masks (balance with moisture).
- Dandruff-prone scalp: Anti-inflammatory and antimicrobial support.
- Oily scalp: Clarifying scalp masks.
- Sensitive scalp, straight, wavy: Low-level extract in shampoos.
What are the benefits of Spirulina?
Spirulina’s benefits are supported by pharmacological reviews and laboratory studies [1–4]:
- Antioxidant: C-phycocyanin, chlorophyll, and carotenoids scavenge free radicals [1, 2].
- Anti-inflammatory: Phycocyanin inhibits COX-2 and inflammatory cytokines [1].
- Wound healing and repair: Spirulina cream showed healing and antioxidant activity in vitro [3].
- Nourishing: Amino acids, vitamins, and minerals support skin and hair.
- Antimicrobial: Activity against skin bacteria and fungi.
- Barrier support: GLA and polysaccharides.
- Hair strength: Protein-rich masks reduce breakage.
- Natural colorant: Green (powder) and blue (phycocyanin) for soap and cosmetics [4].
