Ethan Hartwell | April 4, 2026

Microscopic blue-green algae naturally rich in amino acids, in proteins and in vitamins, spirulina is increasingly used in cosmetics. In what ways and how can it become our best beauty ally?

Spirulina, with its multiple nutritional properties, is one of the millennium superfoods according to UNESCO and the FAO. Beyond its health benefits, this blue-green algae that contains healthy fatty acids and a high level of minerals and vitamins also works wonders in cosmetics: nails, hair and skin will appreciate. In short, spirulina is a natural and eco-friendly way to take care of your inner health, with visible outer results: a boon.

Use spirulina for stronger nails

The quantity and variety of minerals (calcium, iron, magnesium, phosphorus, potassium…) and vitamins (notably A and B12) present in spirulina are essential to nourish the hair and the nails and make them grow more shiny and strong. Striated nails in particular readily regain their strength thanks to spirulina.

Added to external-use shampoos and conditioners, spirulina stimulates hair growth and strengthens it, especially thanks to essential fatty acids and beta-carotene, in addition to all the minerals and vitamins it provides. To maximize these benefits, it is recommended to consume spirulina both orally and topically.

A remedy for hair loss

Rich in iron and copper with an average of 28.5 mg of iron and 6.1 mg of copper per 100 g, spirulina is indicated to prevent hair loss, as well as to facilitate the regrowth of new hair.

Spirulina acts as an antioxidant. It helps strengthen metabolism and ensures a healthier scalp and thus, completely dandruff-free hair after a simple four-week course.

Spirulina: a natural skin booster

Free radicals are the primary cause of tired, sagging, and dull skin. Regular consumption of spirulina supports our metabolism and helps eliminate impurities as well as to restore elasticity and tone to the skin. The facial skin becomes less oily and the essential vitamins on its side make it more radiant.

To reduce wrinkles and expression lines

As we have seen, spirulina helps improve skin elasticity both in masks and when consumed orally. It also contains tyrosine, vitamin E and selenium, components found in many anti-aging creams and treatments for their ability to slow down cellular aging.

Erase dark circles

Spirulina strengthens the immune system, which naturally fortifies the skin and improves the epidermis’ response to irritation and dryness. In addition, its decongestant effect reduces under-eye puffiness.
