What Is Spirulina Subsalsa Extract?
Spirulina Subsalsa Extract is a water or glycerin based extract of Spirulina subsalsa, a blue green microalga from the Cyanophyceae class that grows in brackish and marine waters. The extract is packed with proteins, essential amino acids, B vitamins, vitamin E, carotenoids, the blue pigment phycocyanin plus magnesium, calcium and iron, giving it strong antioxidant and skin nourishing properties.
Spirulina has long been consumed as a nutrient rich food, and its antioxidant reputation led cosmetic chemists to explore it in topical formulas during the 1970s. Spirulina subsalsa offers similar benefits with the added appeal of sustainable marine sourcing, making it a popular choice for eco minded brands.
Production starts with controlled cultivation of the microalga, followed by gentle drying to protect heat sensitive compounds. The dried biomass is then macerated in water or a water glycerin mix. After extraction the liquid is filtered, concentrated as needed and standardized to ensure consistent active content before it is blended into finished products.
You will find Spirulina Subsalsa Extract in sheet masks, rinse off clay masks, daily moisturizers, after sun gels, anti aging serums, soothing body lotions and scalp or hair tonics that promise environmental defense.
Spirulina Subsalsa Extract’s Cosmetic Benefits/Uses
In cosmetic formulations Spirulina Subsalsa Extract serves as a skin protecting agent. By supplying antioxidants and trace minerals it helps neutralize free radicals generated by UV light, pollution and other external stressors while reinforcing the skin barrier. This support can reduce moisture loss, calm the feeling of irritation and promote a healthier looking complexion over time.
Who Can Use Spirulina Subsalsa Extract
This gentle algae extract works for most skin types including dry, normal, combination and oily because it is lightweight, water based and non occlusive. Sensitive skin usually tolerates it well thanks to its soothing antioxidant profile however anyone with a known algae allergy should avoid it.
Spirulina subsalsa is sourced from microalgae so it contains no animal derived material making it suitable for vegans and vegetarians. It is also in line with many clean and reef friendly standards.
Topical use during pregnancy or while breastfeeding is generally considered low risk since the ingredient stays on the surface of the skin and has no known hormonal activity. This is not medical advice and pregnant or nursing women should discuss any skincare product with their doctor to be safe.
The extract does not increase photosensitivity and can be used both morning and night. It pairs well with sunscreen to provide extra antioxidant support against UV induced free radicals.
Potential Side Effects/Adverse Reactions

- Mild redness or stinging in very sensitive skin
- Allergic contact dermatitis in individuals allergic to algae or cyanobacteria

Comedogenic Rating
Rating: 0 – Spirulina Subsalsa Extract is water soluble, light in texture and leaves no oily residue, all of which mean it is very unlikely to clog pores. It contains mainly proteins, vitamins and minerals rather than fatty acids that tend to be pore blocking.
Suitable for acne prone and breakout prone skin.
As with any extract the final formula matters; pairing it with heavy waxes or butters can raise the overall comedogenicity even if the extract itself rates a zero.

Its popularity is growing as brands look for marine derived, eco friendly actives that suit a wide range of skin types.
The ingredient is generally considered safe, non irritating and non comedogenic with only rare allergy risks. It is always wise to patch test a new product containing the extract to make sure it agrees with your individual skin.
