What Is Nannochloropsis Gaditana Extract?

Nannochloropsis gaditana extract is derived from a species of marine microalgae. This ingredient is rich in bioactive compounds, particularly carotenoids and other polyphenols, which give it antioxidant properties.

In skincare formulations, it functions primarily as an antioxidant and skin conditioner. The extract works to neutralise free radicals and support the skin's natural defences against oxidative stress caused by environmental factors such as UV exposure and pollution.

Benefits for Your Skin

How It Works

The carotenoids and polyphenolic compounds in nannochloropsis gaditana extract function as antioxidants by donating electrons to neutralise free radicals. This prevents these unstable molecules from damaging skin proteins, lipids, and DNA.

Additionally, the extract's bioactive compounds may stimulate the skin's own antioxidant enzyme systems, enhancing the skin's intrinsic capacity to manage oxidative stress. This dual mechanism—both direct neutralisation and upregulation of natural defences—makes it a multi-faceted protective ingredient.

Clinical Evidence & References

Research into nannochloropsis gaditana extract in cosmetic applications remains limited. Most evidence derives from in vitro studies demonstrating the antioxidant capacity of marine microalgae extracts, though human clinical data specific to this ingredient is sparse.

The ingredient's safety profile appears favourable based on its use in skincare products and the general tolerability of marine-derived botanicals. However, larger-scale clinical trials would help establish clearer efficacy claims for specific skin concerns.

How to Use

Nannochloropsis gaditana extract is typically found in serums, moisturisers, and protective day creams. It works well in layered routines and pairs effectively with other antioxidants such as vitamin C or vitamin E. As with any new ingredient, introduce it gradually to observe how your skin responds.

Safety & Precautions

Generally well-tolerated and suitable for most skin types. As a marine-derived ingredient, those with specific algae sensitivities should check the full ingredient list or conduct a patch test before use.
