What Is Crithmum Maritimum Callus Extract?

Crithmum maritimum callus extract is derived from plant cells of rock samphire (a coastal plant), cultivated in a laboratory setting. This extract is rich in polyphenols and other compounds with antioxidant properties, which means it can help neutralise free radicals—unstable molecules generated by UV exposure, pollution and other environmental factors that contribute to skin ageing.

As a callus extract, this ingredient is produced through cell culture rather than harvested directly from the plant, which allows for consistent quality and sustainable production without depleting wild populations.

Benefits for Your Skin

How It Works

Antioxidant compounds in the extract donate electrons to free radicals, neutralising them before they can damage skin cells and collagen. This protective action may help slow visible signs of environmental ageing and support overall skin health.

The extract may also support the skin's own antioxidant systems, working synergistically with the body's natural defences rather than simply acting as a single-mechanism ingredient.

Clinical Evidence & References

Research specific to crithmum maritimum callus extract in skincare is limited. Most evidence derives from general knowledge of plant polyphenols and antioxidant activity. The ingredient is used in cosmetics primarily for its anticipated antioxidant function, though controlled human studies demonstrating visible skin benefits remain sparse.

It is generally considered a supplementary antioxidant rather than a primary active, best combined with other proven antioxidants and sun protection as part of a comprehensive skincare routine.

How to Use

This ingredient is typically found in serums, moisturisers and protective products. Use consistently as part of your daily routine, morning and evening, for the best results. It works well alongside other antioxidants like vitamin C or niacinamide, and should always be paired with broad-spectrum SPF during the day.

Safety & Precautions

Generally well-tolerated in skincare formulations. As with all plant extracts, patch test if you have known sensitivities to botanical ingredients.
