What Is Eryngium Maritimum Extract?

Eryngium maritimum extract is derived from sea holly, a coastal plant species with a long history in traditional skincare. The extract is obtained through biotechnological methods that concentrate its active compounds, particularly phenolic acids and flavonoids—plant-derived compounds known for antioxidant properties.

In formulations, this ingredient functions as a tonic, meaning it's intended to help tone and support skin condition. The extract can be processed for enhanced skin penetration, allowing its active components to work more effectively within the skin layers.

How It Works

The phenolic compounds and flavonoids in eryngium maritimum extract work primarily through antioxidant and anti-inflammatory pathways. These compounds neutralise free radicals that can damage skin cells and contribute to visible ageing, whilst simultaneously supporting the skin's natural defence systems.

When formulated with advanced delivery systems—such as multilayered liposomes—the extract can penetrate beyond the outermost skin layer (stratum corneum) to reach deeper tissue, where it may more effectively support skin density, elasticity and barrier function.

Clinical Evidence & References

Clinical trials comparing eryngium maritimum extract formulations to conventional skincare products have shown measurable improvements in skin density, hydration, elasticity and fine line appearance. The extract demonstrated particularly strong results when encapsulated for enhanced delivery, suggesting that formulation method significantly influences efficacy.

The ingredient's polyphenol and flavonoid content is well-documented through phytochemical analysis. However, most clinical data relates to specifically formulated versions rather than the raw extract itself, so efficacy may depend on how the ingredient is processed and delivered in a given product.

How to Use

This ingredient is typically found in serums, creams and treatment products rather than cleansers. Use as directed by the product instructions—usually once or twice daily. It works well alongside other antioxidants and hydrating ingredients, though there's no need to layer multiple antioxidant products unnecessarily. Results tend to develop gradually over consistent use rather than immediately.

Safety & Precautions

Eryngium maritimum extract is generally well-tolerated and suitable for most skin types. As with any plant extract, those with known allergies to plants in the Apiaceae family should exercise caution or patch-test first.
